ABSTRACT

The isolates of fungi Beauveria bassiana (Bb), Metarhizium anisopliae (Ma) and Paecilomyces fumosoroseus (Pf) from the arable land (Bb I, Ma I, Pf I) as well as from the herbicide fallow (Bb II, Ma II, Pf II) of an apple orchard were inoculated on Sabouraud’s medium with an addition of 2 herbicides (Chwastox Extra 300 SL and Roundup) and 3 insecticides (Zolone 35 EC, Basudin 205 EC and Sanmite 20 WG) in the dose 10 times higher than the recommended one (A), the recommended dose (B) and 10 times lower than the recommended one (C). It was shown that the isolates of fungi that in the natural conditions had a contact with herbicides were mostly more resistant to the toxic properties of pesticides as compared with the isolates from the arable land. Herbicides inhibited the growth of fungi more strongly than insecticides. Generally, the fungus P. fumosoroseus was more sensitive to herbicides than B. bassiana. Amon

Key words: pesticides, entomopathogenic fungi, growth, sprouting of spores..
