In this study, in order to identify the fungal pathogens that cause disease in the grapes in the province of Antalya, in 8 districts where grapes are grown, a total of 28 different greenhouses are sampled, soil and diseased plants are taken. As a result of the insulation from the examples, 12 species of fungus have been identified. In soil isolations, the highest prevalence rate is Rhizoctonia solani with 96.43%, while Fusarium spp with 75%. and 35.71 % with Pythium sp. He has watched him. Gliocladium roseum, Alternaria alternata, Aspergillus niger, Penicillium sp., Rhizopus stolonifer, Botrytis cinerea and Verticillium sp. And there were other fungus with low prevalence rates in the soil examples. In the leaf samples Alternaria alternata 96. It was identified as the most common fungus by 43 percent, with Mycosphaerella fragariae observed it by 71.43 percent, while the prevalence rate of Cladosporium cladosporioides was 3.57 percent. In the isolations made from fruits, Botrytis cinerea was found as the most common fungus with a rate of 85.71%, with Penicillium sp with a rate of 35.71. Aspergillus niger was 10.71% of the other fungus that were isolated from the dirty fruit. In the laboratory patogenic testing, all fungus formed their own specific symptoms. According to these findings; in the grains grown in the province of Antalya, A. alternata, M. fragariae and B. cinerea are identified as the most important pathogens, while R. solani, Fusarium spp., Pythium spp., Verticillium spp. It has been found that some soil-based pathogens may also cause serious losses.

The aim of this study was to determine the fungi causing disease in strawberry areas in Antalya province. In the study, 28 strawberry greenhouses from 8 districts were visited. Surveys were performed at two periods; first, two weeks after transplanting, and second one at the beginning of harvest period. In the greenhouses, samples were taken from the plants showing disease symptoms. As a result of isolations, fungi belonging to 12 genera were determined. From the soil samples, Rhizoctonia solani was the most common fungus with 96.43% prevalence rate and Fusarium spp. with 75% and Pythium sp. with 35.71% followed it. Gliocladium roseum, Alternaria alternata, Aspergillus niger, Penicillium sp., Rhizopus stolonifer, Botrytis cinerea and Verticillium sp. were the other fungi found in soil samples with low rates. Alternaria alternata was the most common fungus with the prevalence rate of 96.43%, while Mycosphaerella fragariae followed it with 71.43% and the prevalence rate of Cladosporium cladosporioides was 3.57% in the leaf samples. Botrytis cinerea was the most common fungus in the isolations from the fruit samples with 85.71% prevalence rate, and Penicillium sp. with 35.71% and Aspergillus niger with 10.71% were the other fungi isolated from the rotten fruits. In the pathogenicity tests, all fungi caused typical symptoms on healthy plants. According to these results, A. alternata, M. fragariae and B. cinerea were found as the most important pathogens of strawberries grown in Antalya, while some other soil borne pathogens like R. solani, Fusarium spp., Pythium spp., Verticillium spp. may also cause significant losses.
