Activity of Metalaxyl-M plus mancozeb, Fosetyl-Al, and Phosphorous Acid against Phytophthora Crown and Root Rot of Apricot and Cherry Caused by Phytophthora palmivora
(CZECH ACADEMY AGRICULTURAL SCIENCES, 2017) Derviş, Sibel; Derviş, Sibel; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Crown and root rot, caused by the Oomycete pathogen Phytophthora palmivora, has become a destructive disease of apricot and cherry in eastern Turkey. There are no currently registered fungicides labeled for its control. In greenhouse experiments conducted in 2012 and 2013, 1-year-old potted apricot rootstock Zerdali and cherry rootstock Mahaleb plants were treated either with foliar spray of fosetyl-Al (140, 160, and 180 g a.i./100 l) or phosphorous acid (187.5, 200, and 215 g a.i./100 l) or soil drench of 100 ml of metalaxyl-M (= mefenoxam)+mancozeb (12+192, 16+256, and 20+320 g a.i./100 l) one day after wound inoculation of crowns and roots. In both years, phosphorous acid at 200 and 215 g a.i./100 l, fosetyl-Al at 160 and 180 g a.i./100 l, and metalaxyl-M+mancozeb at 20+320 g a.i./100 l significantly reduced the root rot severity on Zerdali by 70.68-80.00% and crown rot severity on both Zerdali and Mahaleb, by 68.32-91.96 and 74.21-82.60%, respectively, compared with phosphorous acid at 187.5 g a.i./100 l, fosetyl-Al at 140 g a.i./100 l, metalaxyl-M+mancozeb at 12+192 and 16+256 g a.i./100 l and control. Moreover, fosetyl-Al at 180 g a.i./100 l and metalaxyl-M+mancozeb at 20+320 g a.i./100 l significantly reduced the root rot severity on Mahaleb compared to fosetyl-Al at 140 and 160 g a.i./100 l, metalaxyl-M+mancozeb at 12+192 and 16+256 g a.i./100 l, phosphorous acid treatments and control in 2012, providing the best control of the disease by 88.00-90.68%. Two/three phosphorous acid foliar applications at 200 g a.i./100 l suppressed symptom development when field applications were made on a curative basis in 2014 and 2015.

Alternaria alternata causing inner black rot of lemon (Citrus limon) fruits in Turkey: Genetic diversity and characterisation
(ScienceDirect, 2023) Derviş, Sibel; Derviş, Sibel; Fatih Tekin, Tacettin Utku Günen, Göksel Özer; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
The market sales of symptomless lemons in 2020 revealed a persistent and severe internal black rot with browning of the membrane wall and juice sac. To investigate the causal agent, externally symptom-free lemons from Mediterranean locations were sampled from supermarkets, local markets, and bazaars in three southeastern Turkish provinces. Internal black rot symptoms were observed in 13.69% of the 1300 externally symptomless fruits, and Alternaria was isolated from 96.63% of those exhibiting these symptoms. Morphological analysis confirmed the identity of Alternaria alternata in 26 representative isolates collected from various markets and bazaars. To examine genetic diversity or polymorphisms, start codon targeted (SCoT) markers were used. Species identification was based on the sequences of translation elongation factor 1-alpha (TEF 1-α), RNA polymerase second largest subunit (RPB2), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH). SCoT 29 exhibited the highest amount of polymorphic amplicons, with 18 polymorphic bands scored when compared to the other six scoreable markers. The 26 representative isolates from various markets and bazaars were divided into four clades by SCoT 29. However, multilocus sequence analyses confirmed the identification of a single species, A. alternata. In terms of virulence and the impact of temperature on growth, representative isolates from four SCoT clusters were evaluated. Data suggests that SCoT markers can be used to evaluate virulence-based polymorphism in A. alternata; nonetheless, all clades showed comparable temperature responses, with 25 ◦C being the optimum. There was also no association between individual morphotypes and SCoT clade membership. Due to the lack of obvious signs on lemon fruits, producers, merchants, and consumers are unable to identify black rot, and the widespread presence of A. alternata in lemons may pose a significant risk that must be avoided at all costs.
Alternaria spp. causing postharvest decay on apple fruit in Nigde province, Turkey
(2022) Derviş, Sibel; Derviş, Sibel; Özden, Mustafa; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Postharvest rots caused by Alternaria spp. result from infections occurring in the apple orchard at or before harvest and these may remain quiescent during the growing phase and only result in decay during postharvest cold storage. Therefore, the objective of this study was to identify and characterize Alternaria spp. associated with apple black spot and/ or decay during cold storage in Nigde, Turkey. Isolates of Alternaria spp. were obtained from apple fruit (cvs Fuji, Golden Delicious, Granny Smith, Red Delicious, and Starking Delicious) with dark, dry, spongy lesions. The symptomatic fruits were sampled from 18 commercial cold storages in the Nigde Province, Turkey, during the 2020/21 storage period. Decayed fruits were transferred to the laboratory for isolation of the fungi from the lesions. In total, 75 Alternaria isolates were characterized morphologically and were differentiated into 5 phenotypic groups based on their colony morphology, and characteristics of their conidiophores and conidia. At least 5 representative isolates were randomly chosen from each group for the pathogenicity tests. All Alternaria spp. isolates caused round, dry, dark, spongy lesions on/in the inoculated fruits and re-isolates from the inoculated apples of each phenotypic groups were similar to the initial isolates of each group in morphological characteristics. Molecular characterization of isolates is in progress. Since mycotoxin produced by Alternaria spp. in fruits is of unavoidable risk to human health, special care should be given in regards to the need to reduce widespread postharvest losses caused by Alternaria spp. in the cold storages of Niğde, which is the most important apple producer province of the country.

Developing as an alternative plant disease control method by using beneficial microorganisms and their metabolites has gained so much importance in recent years. In this study, the possibilities of using microorganisms which have potential antimicrobial effects on controlling soil-borne fungi at strawberry production were investigated. Effects of different lactic acid bacteria (LAB) strains on the development of several soil-borne fungi were studied in vitro and in vivo. LAB were screened for antifungal activity by using cell free supernatant against Fusarium sp., Rhizoctonia sp., Macrophomina sp., Botrytis sp., Phtopythium sp., Cylindrocarpon sp. and Pestalotiopsis sp. Cell free supernatant of LAB isolates showed promising antifungal activity. In vitro effective strains of LAB were tested in pot experiments to search their effects on disease development and plant growth. While the antifungal effects of all LAB strains tested in vitro experiments exhibited promising results, in vivo experiments revealed similar effects on different fungi genera.

(2023) Derviş, Sibel; Türkkan, Muharrem; Yiğit, Abdurrahman; Derviş, Sibel; Özer, Göksel; Erper, İsmail; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Neoscytalidium dimidiatum has been recently identified as the agent responsible for canker, dieback, shoot blight, and root rot on different hosts in Türkiye. In this study, we evaluated the inhibitory effect of boric acid (H3BO3), three borates [disodium octaborate tetrahydrate (Na2B8O13.4H2O), disodium tetraborate decahydrate (Na2B4O7.10H2O) and disodium tetraborate (Na2B4O7)] on the mycelial growth, germ tube elongation and conidial germination of N. dimidiatum. The antifungal effects of the boron compounds were investigated at 0.125, 0.25, 0.5, 1.0 and 2.0% (w/v) concentrations. The differences observed between the inhibitory effects of boron compounds on the parameters were found to be significantly important at P < 0.05. The 0.5% concentration of disodium tetraborate decahydrate and disodium octaborate tetrahydrate completely inhibited the fungus, whereas other salts did not. Disodium tetraborate decahydrate and disodium octaborate tetrahydrate completely inhibited three parameters at 0.5% and higher concentrations. However, boric acid and disodium tetraborate were able to completely inhibit investigated factors of N. dimidiatum at 2.0% and 1.0% concentration, respectively. Disodium tetraborate and boric acid at 0.5% concentration decreased germ tube elongation and conidia germination of the fungus by 94.97%-63.57%, 59.33%-51.26%, respectively. The effectiveness of the 0.5% concentration on conidial germination was also similar in both salts at P < 0.05. However, disodium tetraborate inhibited germ tube elongation more effectively than boric acid. The minimum inhibition concentration (MIC) values of the four boron compounds also varied between 0.5% and 2.0% concentrations. The boron compounds in this study could be potential agents to manage N. dimidiatum.

Forty-nine endophytic bacteria were isolated from pepper stem and crown and forty-nine bacteria from soil. Isolates were obtained from pepper grown fields of Bozova and Hilvan Districts of Şanlıurfa. Antagonistic effects of endophytic bacteria and soil-borne bacteria were in-vitro tested against Fusarium solani, F. oxysporum, Macrophomina phaseolina and Rhizoctonia solani in petri dishes. Bacterial isolates from soil and endophytic bacteria revealed antagonistic activity of 79.37-20.22% and 81.69-33.47%, respectively against four pathogens.Statistically significant differences were found among the efficiencies against four different pathogens. Additionally, bacteria isolated from Bozova province were found to have higher antagonistic activity than those of Hilvan province. The antagonistic activity of endophytic bacteria was found to be higher than that of bacterial isolates from soil. In later studies, effective endophytic bacteria isolated from pepper can be used against soilborne pathogens

Wheat (Triticum spp.) is the third most important crop in terms of global production, with an average annual production of almost 219 million ha and yielding 760.9 million tons, after maize and rice. However, A complex of fungi attacking the crown and root tissues of wheat causes a serious problem and significant yield reductions in wheat. Although most prevailing species in this complex can change yearly and regionally in dryland winter wheat production areas, Bipolaris sorokiniana Shoemaker (teleomorph: Cochliobolus sativus) is one of the dominant species and causes spot blotch and common root rot (CRR) on wheat plants, especially in winter wheat varieties. Comprehensive surveys were conducted to identify B. sorokiniana associated with CRR of wheat throughout the main wheat-growing areas of Azerbaijan and Kazakhstan in 2017 and 2019, respectively. As a result of the classification of species based on morphological and molecular tools, 96 and 547 isolates were identified as B. sorokiniana for Azerbaijan and Kazakhstan, respectively. All surveyed regions for these countries were contaminated with this pathogen. Some representative isolates of B. sorokiniana were tested for their ability to cause disease and produced moderate disease severities on cultivar Seri 82 (Triticum aestivum, bread wheat). The percent incidence of B. sorokiniana isolates in all isolates was 15.2% for Azerbaijan, whereas, for Kazakhstan, B. sorokiniana was the most frequently recovered species in the three regions surveyed, with an isolated frequency of 44.80%. The results of the current study provide crucial and helpful information to improve disease management strategies against CRR of wheat in these countries.

Canker and leaf scorch on olive (Olea europaea L.) caused by Neoscytalidium dimidiatum in Turkey
(ScienceDirect, 2022) Derviş, Sibel; Özer, Göksel; Türkölmez, Şahimerdan; Derviş, Sibel; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
In a recent survey of olive groves in the Southeast Anatolia Region of Turkey, a new and serious decline of olive trees, beginning with foliar scorching and then dieback of twigs, branches, and even whole trees, was observed for the first time. In more advanced stages of the disease, necrosis and cankers were observed on the bark of the trunk, branches, and twigs. Isolations from symptomatic tissues from multiple cultivars in diverse locations yielded Neoscytalidium dimidiatum, which were identified using ITS, tef1, and tub2 loci of genomic DNA, in combination with morphological data. In vitro studies showed that conidial germination, hyphal growth, and pycnidia formation of the pathogen were positively correlated with elevated temperatures. Wild type olive “Delice”, “Edincik Su”, and “Memecik” seemed like the most resistant cultivars on which disease severity values were the lowest among 14 screened olive cultivars in two experimental orchards under natural conditions. Pathogenicity tests showed that “Gemlik” was the most susceptible cultivar showing the largest cankers and extensive scorch lesions. Isolates caused canker but not leaf scorch on O. europaea cultivars “Arbequina” “Halhalı”, “Manzanilla”, “Nizip Yağlık”, and “Saurani”. Neoscytalidium isolates are likely to have a negative impact on the health of diverse olive groves, which are primarily confined to Mediterranean-type climatic regions. These findings suggest an increased risk of infection in environments with increasing temperatures, as is common in the Southeast Anatolia Region of Turkey. The information gathered in this study will be used to examine the disease's epidemiology and establish disease control initiatives. This is also the first report of N. dimidiatum infecting O. europaea in the world.

Characterization and pathogenicity of Pythium-like species associated with root and collar rot of kiwifruit in Turkey
(In Plant Disease, 2021) Derviş, Sibel; Özer, Göksel; Karaca, Gürsel; Erper, İsmail; Derviş, Sibel; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
During the period of June to October in 2018, a widespread decline was observed on kiwifruit vines in the vineyards located in Altınordu, Fatsa, and Perşembe districts of Ordu province. The symptoms were associated with reddish-brown rots expanding from the root to the collar with sparse off-color foliage. Based on the percentage of the total infected samples across 18 vineyards, the most common oomycete species were Globisporangium intermedium (37.1%), Phytopythium vexans (34.3%), G. sylvaticum (14.3%), G. heterothallicum (11.4%), and Pythium dissotocum (2.9%). The morphological identification of isolates was confirmed based on partial DNA sequences containing the nuclear rDNA internal transcribed spacer region (rDNA ITS) and the mitochondrial cytochrome c oxidase subunit II (coxII) gene. The optimum growth temperature and the optimum pH of 5 species ranged from 22.98 to 28.25°C and 5.67 to 8.51, respectively. Pathogenicity tests on the seedlings of kiwifruit cv. Hayward revealed significant differences in virulence among isolates. Phytopythium vexans and G. sylvaticum isolates caused severe root and collar rot resulting in seedling death, while G. heterothallicum and G. intermedium isolates had relatively lower virulence. All Globisporangium spp. and P. vexans isolates significantly decreased plant growth parameters (plant height, shoot and root dry weights and root length); however, P. dissotocum caused very mild symptoms and did not affect these parameters of growth. To our knowledge, this is the first study reporting G. sylvaticum, G. heterothallicum, and G. intermedium causing root and collar rot on kiwifruit not only in Turkey but also in the world.

Clonostachys rosea Strain ST1140: An Endophytic Plant-Growth-Promoting Fungus, and Its Potential Use in Seedbeds with Wheat-Grain Substrate
(SpringerLink, 2023) Derviş, Sibel; Özer, Göksel; Derviş, Sibel; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
In this study, Clonostachys rosea strain ST1140, a naturally occurring endophyte in healthy roots of a pistachio tree, was identifed morphologically and molecularly through DNA sequencing, and its endophytic ability and growth efect in/on three solanaceous plant species were tested. Three diferent organic substrates (bread wheat-grain, sawdust, and leonardite) were also investigated for their utility in cultivating and multiplying the strain. In-tray and pot experiments, the rates of seed germination and vegetative development of pepper, tomato, and eggplant inoculated with C. rosea at planting were compared to those of non-inoculated controls. In pot experiments, inoculating seedbeds with increasing doses of C. rosea strain ST1140 with wheat-grain substrate resulted in higher plant height values for all plant species, and the strain endophytically colonized the roots of all plant species. In-tray experiments revealed that ST1140 inoculation resulted in 2–4 days earlier and 10% higher germination rates for all plant species, as well as more vigorous and accelerated seedling growth (10–13 days earlier for seedlings at the 4–5 true leaf stage) on all inoculated plant species. Among three diferent organic substrates, wheat-grain was found to be the most efective for long-term cultivation and multiplication of the fungus, which could be of interest for its development as a commercial product. These results promised the strain ST1140’s use as a biofertilizer in seedbeds with a wheat-grain substrate.
Correction to: Leaf spot caused by Alternaria crassa on Datura stramonium in Turkey
(Australasian Plant Disease Notes, 2022) Derviş, Sibel; Alkan, Mehtap; Derviş, Sibel; Özer, Göksel; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16.

In August 2021, jimson weed (Datura stramonium) plants growing as weeds in potato fields in Bolu province, Turkey, exhibited leaf spots with dark concentric rings. Sunken and lens-shaped lesions with a light center were also frequently observed on petioles, branches, and stems. Based on morphological characteristics and phylogenetic analysis of the transcription elongation factor 1-α, RNA polymerase second largest subunit, and glyceraldehyde-3- phosphate dehydrogenase loci, the causal agent was identified as Alternaria crassa. The pathogen was successfully re-isolated from inoculated jimson weed plants in the pathogenicity assay, proving Koch’s postulates. Alternaria crassa caused necrotic lesions on potato plants, similar to those of early blight, confirming them as an alternative host of the pathogen. This is apparently the first report of leaf spot caused by A. crassa on jimson weed in Turkey.

The Effect of Talaromyces funiculosus ST976 Isolated from Pistacia vera Rhizosphere on Phosphorus Solubility in Soil Samples with Different Physicochemical Properties
(Kahramanmaraş Sütçü İmam Üniversitesi Tarım ve Doğa Dergisi, 2022) Derviş, Sibel; Eren, Abdullah; Eren, Abdullah; Özer, Göksel; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
In this study, a total of 78 Talaromyces isolates were isolated from the pistachio (Pistacia vera L.) rhizosphere heavily infested with Neoscytalidium spp. The identification studies of the four representative isolates based on morphological and molecular methods showed that all isolates were T. funiculosus. The 575 bp long sequence of the internal transcribed spacer region of T. funiculosus isolate ST976, selected as a representative of the isolates, was deposited in GenBank under accession no. MW130842. The Maximum Likelihood tree clustered the ST976 isolate with reference T. funiculosus isolates derived from the GenBank nucleotide database. The phosphorus dissolution ability of ST976 isolate was determined by an experiment using six soil samples collected from agricultural lands in various locations of Şanlıurfa province. The pH of the soil samples taken varied between 7.21 and 7.88. As a result of the analysis performed with the addition of the isolate ST976 applied to soil samples with different soil structures (Clay and Clay-Loam), it was determined that the isolate ST976 dissolved 109–311% more phosphorus than the control sample. The study is one of the first studies proving the ability of T. funiculosus isolate ST976 to dissolve phosphorus without any additives to soil solution was determined.
Effects of Row Spacing on Yield and Quality of Forage Pea (Pisum sativum ssp. arvense)
(Turkish journal of range and forage science (Online), 2022) Karadeniz, Erdal; Bengisu, Gülşah; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Peas are globally used as forage, haylage, silage or straw in ruminants’ diet. Winter forage pea is also becoming an important forage crop, particularly for haylage production in Türkiye. Row spacing produce different spatial arrangements that influence competition for resources, especially radiation, in forage pea production. The aim of this study is to determine the appropriate row spacing for forage peas depending on hay yield and quality. Field experiments were performed Kızıltepe district, Mardin province of Türkiye during winter growing seasons of 2018-2019 and 2019-2020. Özkaynak pea variety was used in the experiments. Three row spacings (RS) (20, 30 and 40 cm) were applied. The experimental units had an area of 12 m2 (2.4×5) in size and equal seed rate was used in each experimental unit (on 150 kg ha -1 ). Higher plant height (127.8 cm) was recorded under 20 cm RS, compared to 30 (121.8 cm) and 40 cm (121.2 cm). The average green forage yield was 26.7, 27.7, and 28.8 t ha-1 for 40, 30, and 20 cm RS, respectively. Whereas the average hay yields for 20, 30, and 40 cm RS were 5.20, 5.34, and 5.79 t ha-1 , respectively. Crude protein (CP) ratio was significantly lower for 40 cm (20.2%) RS compare to 20 (22.5%) and 30 (21.6%) cm RS. Average raw ash, dry matter uptake (DMI) and relative nutritional value (RFV) ratios significantly increased in 30 cm and 40 cm RS compared to the 20 cm. However neutral detergent fiber (NDF) ratio decreased in 30 cm and 40 cm RS compared to 20 cm. Acid detergent fiber (ADF) and digestible dry matter (DDM) were not significantly affected from RS. In conclusion, 20 cm RS would be more suitable and economical due to higher plant height, green forage and hay yields, and higher CP and NDF rates for commercial feed producers in the region. However, 30 cm RS may be more suitable for farmers producing feed for their own livestock due to higher DMI and RFV values.

(Polish Society Magnesium Research, 2021) Eren, Abdullah; Toncer, Ozlem; Eren, Abdullah; 16.01. Department of Organic Agriculture / Organik Tarım Bölümü; 16. School of Vocational Higher School of Kızıltepe/ Kızıltepe Meslek Yüksekokulu; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
Nanotechnology is a research subject in many interdisciplinary engineering fields today. Nanoparticles have important effects on seed germination and seedling growth of plants. The aim of this study has been to produce a 54.68 nm-sized ZnO nanoparticle obtained from the Nigella sativa L. plant by green synthesis. The effect of medicinal sage (Salvia officinalis L.) on germination of plant seeds and seedling growth was investigated. The trial was set up under controlled conditions and conducted for 14 days according to a factorial trial design with 5 replications for each dose (0, 0.5, 1.5 and 2.5 mg ZnO NP kg-1). As a result of ZnO NP application in different doses, germination of Salvia officinalis L. seeds varied between 90-94%, stem length was 1.86-2.92 cm and shoot length was between 1.01-1.98 cm. The highest root and shoot length was obtained after the application of 2.5 mg ZnO kg-1 NP. In the light of the results, ZnO nanoparticles are thought to be useful for seed development and agricultural applications.

Neoscytalidium dimidiatum, a member of the Botryosphaeriaceae family, has emerged as a significant pathogen causing canker and blight diseases in various fruit trees, field crops, park and forest trees, and other hosts. Neoscytalidium dimidiatum is the only recognized species within the genus, with the other two previously recognized species, N. novaehollandiae and N. orchidacearum. There is no suggested chemical control method against Neoscytalidium. In this study, we evaluated the inhibitory effect of some salts on the mycelial growth, germ tube elongation and conidial germination of the N. dimidiatum isolate phylogenetically clustered with the isolates previously recognized as N. novaehollandiae. The antifungal effects of the salts were determined at 0.125, 0.25, 0.5, 1.0 and 2.0% (w/v) concentrations of salts in vitro conditions. Statistically, differences were observed between the inhibitory effects of six salts on the parameters at P ≤ 0.05. The 0.25% and higher concentrations of the ammonium bicarbonate and ammonium carbonate salts completely inhibited mycelial growth, germ tube elongation and conidial germination. Potassium and sodium bicarbonate salts in the highest concentration (2.0%) were able to decrease the mycelial growth, germ tube elongation and conidial germination with the rates of 95.58%-95.58%, 95.05%-95.76% and 77.44%-82.91%, respectively. In addition, potassium and sodium carbonate were able to completely inhibit investigated factors of the pathogen at 2.0% and 1.0% concentrations, respectively. The minimum inhibition concentration values of the ammonium bicarbonate, potassium carbonate and sodium carbonate varied between 0.25% and 2.0%. The minimum fungicidal concentration values of the ammonium carbonate and bicarbonate also ranged between 0.25% and 1.0%. As a result, this study showed that salts of carbonate and bicarbonate could be recommended to manage diseases caused by N. dimidiatum.

This study investigated the socio-economic factors affecting the adoption of innovation in small ruminant production in TRC3 region in Turkey. Stratified random sampling technique was used to select 366 small ruminant farmers from the region. Semi-structured questionnaire was used to collect main data for the study. Data collected were analyzed using descritive statistics, t-tests and multiple linear regression analysis. Results of the study showed that the farmers had a mean age of 45,8 years and 97,0% were male. Traditional production was dominant among the small ruminant producers and as the number of animal increases the income increases (p< 0,01). Out of twelve independent variables, eight of them were statistically significant on multiple linear regression analysis. The F-statistics was statistically significant at 1% level on communication behavior and animal health practices; 5% level on age, breeding reasons, milking way, produced products and fold type. The coefficient of multiple determination (R2) value was estimated to be 0,470 this implies that 47,0% of total variation in the output of small ruminant production was accounted for by the independent variables that were fitted into the model. The main problems of small ruminant production were high feed prices, high deaths of lamps/goat, insufficient use of pastures because of security problems and lack of shepherd due to young people unwillingness to live in rural areas.
