Compatibility of Polyoxin D zinc salt 5% SC against various biocontrol agents used in grapes

Abstract

Polyoxin D zinc salt 5%SC is a new, medium risk fungicide.The compatibility of the fungicide @ 600 and 1200 ppm was investigated withTrichoderma viride, Bacillus subtilis, Pseudomonas fluorescence, Ampelomyces quisqualis, Beauveria bassiana, Metarhizium anisopliae and Paecilomyces lilacinus under in vitro conditions. It was observed that Polyoxin –D zinc salt @ 600 and 1200 ppm were compatible with Trichoderma viride, Bacillus subtilis and Pseudomonas fluorescens, Ampelomyces quisqualis, Metarhizium anisopliae and Paecilomyces lilacinus but in case of Beauveria bassiana the fungicide was incompatible. Thus Polyoxin D zinc salt 5% SC @ 600 ppm may be recommended against powdery mildew of grapes and may be used in tandem with the bio control agents used in grapes
