Compatibility of Copper hydroxide (Kocide 3000) with Biocontrol Agents

Abstract

An experiment was conducted to study the compatibility of copper hydroxide (Kocide 3000) with bacterial and fungal biocontrol agents under in vitro conditions. Bacterial biocontrol agents viz., Pseudomonas fluorescens and Bacillus subtilis were compatible with copper hydroxide (Kocide 3000) even at a high concentration of 300 ppm. Fungal biocontrol agent, Trichoderma viride was inhibited by copper hydroxide at a concentration above 2500 ppm. The fungal biocontrol agent was highly compatible with the fungicide than the bacterial biocontrol agents.
