In the protection of grapevine from causal agent of downy mildew (Plasmopara viticola), powdery mildew (Uncinula necator) and gray mold (Botrytis cinerea) and anti-resistant strategy

Abstract

Economically the most important diseases that occur on grapevine are causal agent of downy mildew (Plasmopara viticola ((Berk. &. Curt.) Berl. & de Toni), causal agent of powdery mildew (Erysiphe necator (Schw.) Burrill) and causal agent of gray decay (Botrytis cinerea Pers.). A large number of registered fungicides for control of these phytopathogens in Serbia is at the same time an indicator of their spread and harmfulness. For the control of downy mildew in Serbia are registered 121 preparation based 36 active ingredients, while for the control of powdery mildew are registered 56 preparations based on 25 active ingredients, and for the suppression of gray mold 14 preparations based on 9 active ingredients. The aim of this study was to display the registered fungicides for suppression of before mentioned, economically important pathogens of grapevine (downy mildew, powdery mildew and gray mold), as well as the basic measures for anti-resistant strategies, considering that all three pathogens, as well as most fungicides used for their suppression, belong to groups of high risk for resistance developement.

Ekonomski najznačajnije bolesti koje se javljaju na vinovoj lozi su plamenjača (prouzrokovač Plasmopara viticola ((Berk. & Curt.) Berl. & de Toni), pepelnica (prouzrokovač Erysiphe necator (Schw.) Burrill) i siva trulež (prouzrokovač Botrytis cinerea Pers.). Veliki broj fungicida registrovanih kod nas za suzbijanje pomenutih fitopatogenih gljiva je ujedno i pokazatelj njihove rasprostanjenosti i štetnosti. Za suzbijanje prouzrokovača plamenjače u Republici Srbiji je registrovano 121 preparat na bazi 36 aktivnih supstanci, dok je za suzbijanje prouzrokovača pepelnice registrovano 56 preparata na bazi 25 aktivnih supstanci, a za suzbijanje prouzrokovača sive truleži 14 preparata na bazi 9 aktivnih supstanci. Cilj ovog rada je bio da se za pomenute, ekonomski najznačajnije patogene vinove loze (prouzrokovače plamenjače, pepelnice i sive truleži), prikažu registrovani fungicidi za njihovo suzbijanje, kao i osnovne mere antirezistentne strategije, s obzirom da sva tri patogena, kao i većina fungicida koji se koriste za njihovo suzbijnaje, pripadaju grupama sa visokim rizikom od nastanka rezistentnosti.
