Ergosterol biosynthesis inhibitor - propiconazole offers possibility of integration of bioagents and insecticides in pest management practices.

摘要

Ergosterol biosynthesis inhibitor - propiconazole was compatible with bacterial biocontrol agents viz., Pseudomonas and Bacillus under in vitro conditions. The compatibility assessed using propiconazole amended nutrient and King's B broth at different concentration (250, 500, 750, 860 and 1000 ppm) by turbidimetic method and it was observed that the bacterial growth was not affected by propiconazole even at the highest concentration of 1000 ppm. The turbidity increased with increase in incubation time as compared to control. Further, this fungicide was physically and biologically compatible with three insecticides namely chlorpyriphos, dicofol and methyl-demeton at their respective recommended dosage under laboratory and glasshouse conditions.
