FIELD: agriculture.
SUBSTANCE: invention relates to agriculture and can be used for increasing biological effectiveness of insecticides based on Bacillus thuringiensis bacteria. Increased efficiency of biological insecticides is achieved by using chlorogenic acid as a synergistic bacteria. Percentage increase in the Colorado potato beetle larvae mortality is shown by combined application of chlorogenic acid and spore mixture and crystalline endotoxin of entomopathogenic bacteria Bacillus thuringiensis ssp tenebrionis.
EFFECT: combined use of chlorogenic acid and pure crystalline endotoxin of entomopathogenic bacteria Bacillus thuringiensis ssp tenebrionis provides a reliably high level of synergism, which is expressed in an increase in loss of larvae of the Colorado potato beetle.
