Abstract Cercospora leaf spot is an important foliar disease in sugar beet caused by beticola . Tolerant cultivars are available, but application of fungicides still mandatory for control. The timing the fungicide crucial as it determines outcome epidemiology. A incidence (DI) 5% widely used a threshold application. Recently method was developed that allows quantification aerial spore dispersal...

Pjegavost lista, koju uzrokuje gljiva Cercospora beticola, najzna?ajnija je bolest koja se javlja na še?ernoj repi u svim podru?jima uzgoja i zna?ajne ekonomske štete. Pjege, kao tipi?ni simptomi ove bolesti, naj?eše?e su veli?ine 2-5 mm, svjetlije sredine tamnijeg ruba. Prvo javljaju starijim listovima, ali kako napreduje pjege šire mla?e listove. Najvažnije mjere zaštite podrazumijevaju uništ...

Cercosporin is a non-host-selective, perylenequinone toxin produced by many phytopathogenic Cercospora species. The involvement of Ca(2+)/calmodulin (CaM) signaling in cercosporin biosynthesis was investigated by using pharmacological inhibitors. The results suggest that maintaining endogenous Ca(2+) homeostasis is required for cercosporin biosynthesis in Cercospora nicotianae. The addition of ...
