Abstract

An experiments was conducted in the plots infested with Meloidogyne incognita to evaluate the efficacy of oil cakes (neem and jatropha oil) and bio control agents (Purpureocillium lilacinum, Trichoderma viride and Pseudomonas flourescens) and Carbofuran 3G. Plant growth parameters, fruit yield, root galling, egg production and final nematode population densities were recorded after 90 days of germination. The experimental results revealed that all the management modules significantly increased the growth of okra plants with decrease number of galls & egg masses per plant, number of eggs per egg mass and nematode population. Soil application of jatropha oil cake @ 1.0 t/ha + seed treatment with T. viride and P. fluorescens, each @ 5g/kg seed + soil application of P. lilacinum @ 2.5kg/ha resulted maximum increase in plant growth with highest reduction in nematode population over check followed by soil application of neem oil cake @ 1.0 t/ha+ seed treatment with T.viride & P.fluorescens, each @ 5g/kg seed + soil application of P.lilacinum@ 2.5kg/ha, which were statistically at par. But soil application of neem oil cake @ 1 t/ha + seed teatment with T. viride & P. fluoroscence @ 5 g each/kg seed + soil application of P. lilacinum @ 2.5 kg/kg having the highest B: C ratio (2.12) among the non chemical management treatments was adjudged as the best promising integrated management module against rootknot nematode.

8 of 12 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
