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 Polyversum ™ (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 Polyversum
™ 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.
