Efikasnost biofungicida Polyversum™ u suzbijanju Botrytis cinerea Pers. na plodovima maline

Efficacy of a biological fungicide product, Polyversum™ (Pythium oligandrum Drechsler), in controlling grey mould of raspberries Botrytis cinerea Pers. was tested at sites around Valjevo, Požega and Šabac in 2004, 2005 and 2006. The experiments were conducted and data processed using EPPO methods. Efficacy was found to be significantly lower statistically in the experimental variants involving Polyversum™ biofungicide (E = 18.0%-53.9%) than the standard botricide Ronilan- DF (E = 56.6%-90.3%). Our results show that the biological product Polyversum™ achieved significant efficacy, although poorer than the standard fungicide Ronilan-DF. As it is a biological product almost entirely free of any toxicological and ecotoxicological limitations, it offers a significant advantage for widespread usage in plant protection.U toku 2004, 2005. i 2006. godine, na lokalitetima Valjeva, Požege i Šapca, ispitivana je efikasnost biološkog preparata PolyversumTM (Pythium oligandrum Drechsler) u suzbijanju prouzrokovača sive truleži plodova maline Botrytis cinerea Pers. Eksperimenti su izvedeni i podaci obrađeni po metodama EPPO. Utvrđeno je da je u varijantama primene biofungicida PolyversumTM efikasnost (E = 18.0%- 53.9%) statistički značajno slabija od standardnog botriticida Ronilan- DF (E = 56.6%-90.3%). Ispoljena efikasnost biološkog preparata Polyversum je značajna, iako slabija od standardnog fungicida Ronilan- DF. S obzirom da je reč o biološkom preparatu koji gotovo da nema toksikoloških i ekotoksikoloških ograničenja, to mu daje značajnu prednost za širu upotrebu u zaštiti bilja
