FIELD: agriculture.
SUBSTANCE: improvement of effectiveness of insecticidal preparation is achieved through the use in sublethal doses of a mixture of fluorinated usnic acid (FUA) of the formula 
and 
II obtained by the reaction of (+)-usnic acid with perfluoropropene as a synergist of such insecticides. The decline of the latent period of the disease and increased mortality rate of larvae of Colorado potato beetle is marked using FUA and entomopathogenic microorganisms of Beauveria bassiana, Metarhizium anisopliae and Bacillus thuringiensis. The mixed composition of FUA at a concentration of 0.03% with a suspension of conidia of the fungus Bauveria bassiana with a titer of 3×106 conidia/ml (in vitro) and 5×106 conidia/ml (in the field) has proved to be the best in all respects.
EFFECT: increased biological efficiency of insecticides based on entomopathogenic fungi and bacteria.
