Abstract :

A novel process to produce biopesticides based on Trichoderma harzianum, Pochonia chlamydosporia, Bacillus subtilis and Pseudomonas fluorescens have been invented. The bio-pesticides were developed by taking 1 part of stock culture (sawdust: soil: 5% molasses, 15:5:1) of the biocontrol agents and 20 parts carrier (fly-ash: soil: 5% molasses mixture, 5:3:1) (w/w). Greatest CFU counts of the microorganisms were recorded at 25oC or room temperature during 2�12 weeks of 32 weeks long shelf life test. Seed treatment with the biopesticides at the rate of 5 g/kg seeds carried 103-6 CFU/g seed of chickpea and pigeonpea. The treatments with T. harzianum and P. chlamydosporia effectively controlled the wilt (Fusarium oxysporum F. sp. Ciceri, Fusarium udum) and root knot (Meloidogyne incognita) on chickpea (Cicer arietinum L.) and pigeonpea (Cajanus cajan L.) and greatly reduced the soil population of the pathogens. The biocontrol agents established in the soil and their CFU increased significantly (p<0.05), being greater in pathogen infested soils (p<0.05) than non-infested soil during 4 months period.
