An IPM module with safe pesticide residues on cabbage, with already proven treatments such as carbosulfan, dimethoate, cypermethrin + profenofos and mancozeb under chemical method of control; NSP, Bacillus thuringiensis and Trichogramma bactrae under non chemical method of control were revalidated individually and in combination. Six releases of parasitoid T. bactrae at weekly intervals starting from 12 days after transplanting or spray of NSP 4% at 10-15 days interval, 4 times, starting from 20 days after transplanting, foliar spray of dimethoate and mancozeb gave good control of aphids, leaf blight and black rot respectively. Based on the effectiveness of the treatment and pesticide residues below their permissible levels in cabbage at harvest, a module was developed and tested in the field. The IPM package thus developed was found to control the pests effectively and at the same time the residues on the crop were within the safe limits.Keywords

Biological control agents, Glomus mosseae IIHR, Bacillus subtilis IIHR-1, Pseudomonas fluorescens IIHR+3, Trichoderma harzianum IIHR P1 and T. viride IIHR P22 were evaluated against tomato wilt caused by Ralstonia solanacearum in pathogen-infested plots during 2003-2004. Microbial preparations were applied either as transplant ischolar_main dips or ischolar_main dip plus soil drench 30 days after transplanting. Per cent survivability increased with the use of all biological control agents tested. However, G. mosseae treated plants resulted in better survival (25.75 and 28.79% in ischolar_main dip alone and 60 and 66.67% in ischolar_main dip plus drench against untreated control 0 and 1.5% during 2003 and 2004 respectively), compared to the rest of the treatments, suggesting G. mosseae amendment to pathogen-infested soil would result in substantially higher plant survival against the untreated controls.Keywords
