Compatibility of Bio-control agents with bactericides for controlling bacterial wilt of tomato


Author(s): Divya Sharma and Yogendra Singh

Abstract: A study was undertaken to evaluate the compatibility of bactericides at recommended dosage, half of the recommended dosage and one-fourth of the recommended dosage with Trichoderma harzianum, Bacillus subtilis and Pseudomonas fluorescens that are being used as biocontrol agents. On the basis of mycelial growth and spore germination in case of T. harzianum and on the basis of optical density in case of B. subtilis and P. fluorescens the tested bactericides streptomycin, ampicillin, chloramphenicol, copper hydroxide and chitosan were found compatible. Bleaching powder was found to be incompatible with fungal biocontrol agent whereas found to be compatible with bacterial biocontrol agents. Under glass house condition, all the tested bactericides except bleaching powder when used in combination with biocontrol agents were found effective in controlling bacterial wilt disease of tomato. Combination of bactericides with biocontrol agents was far more effective in controlling disease as compared to when used alone.
