مرکز منطقه ای اطلاع رساني علوم و فناوري - Determination of Soil-Borne and Foliar Fungal Disease Agents of Greenhouses in Kumluca District

Abstract :

Main purpose of the study is to isolate the soil and leaf borne fungal diseases and to determine the prevalence causing serious production loss in the greenhouses of Kumluca in Antalya province. A small scale survey was performed with growers on diseases and control methods. In the survey study, producer experiences about production as well as plant protection problems encountered were recorded. According to the survey results, tomatoes and peppers were the most common vegetables grown in Kumluca and growers were willing to improve themselves about cultivation and plant protection. Total of 272 plant samples showing disease symptoms were collected from vegetable greenhouses in Kumluca and isolations were made during growing season in the period of September 2013 - June 2014. Macroscobic and mikroscobic studies have been conducted on isolated samples to identify soil and leaf born fungal diseases. The most common isolated Genus was Fusarium sp. in greenhouses. Disease prevalance of Fusarium sp. was 20.3-57.4% in cucumber and 43.3-82.1% in melon. Botrytis cinerea was widespread in and showed by 3.6-46.4% disease prevalence ratio. The other fungal diseases isolated from different greenhouses were Cladiosporum sp., Rhizoctonia solani, Verticillum dahliae, Phytophthora sp., Alternaria sp., Sclerotinia sclerotiorum and Sclerotium rolfsii. Disease prevalence of Sclerotinia sclerotiorum on tomatoes was 2.4-12.1% and Sclerotium rolfsii was 8.0-10.0% on eggplant. Rhizoctonia solani occured by 14.1-25.7% in tomato greenhouses.
