In this work was compared fungicide applications in trial vineyard of Semillon cv. with thatof several grower vineyards the effectiveness to fruit infection of Botrytis cinerea at harvest. Studies were conductedat five sites in Tekirdağ. All fungicide treatments reduced mean B. cinerea berry infection when compared to theunsprayed control treatment. Trial programme resulted in at least disease severity (1.46%) and incidence (5.83%) andthis programme was used fungicide at flower stage for B. cinerea. The highest disease severity (11.46%) and incidence(31.67%) was noted in Grower I Programme. This is followed by Grower III programme, Grower II programme andGrower IV programme, respectively. The recommendation for control of B. cinerea in the Trakya region is to applyone spray at bloom.eninfo:eu-repo/semantics/openAccessZiraat MühendisliğiArticle1536167328878
