A szőlő feketerothadás kórokozó áttelelésének megfigyelései és a fungicides védekezés lehetőségei

Abstract

It can be safely claimed that the main result of my laboratory tests, is that the survivor formula remains infectious for several years, and the conidia also plays a role in the primary infection. We think probable that during the overwintering period static formulas can be observed in the fruiting body. We think this may be the overwintering formula. In spring the fungus creates its sexual and asexual sopre-forming during the transformation of these formulas. Further more comprehensive research is needed, which are scheduled earlier, for determining the role of the microconidial (andromoph) forms in the overwintering. The pesticide experiments can be regarded only as initial attemts, the collection of information/data must be continued. It can be safely claimed that the main result of the experiment is that Dynali, which has been recently approved by the new EU directives, proves an excellent antidote against the disease. (Dynali got the permission against the black rot of grapes, although in Hungary there were not any Hungarian experiment results available only data from other EU countries.) Compared to other products its efficiency was outstanding in both years.
