ABSTRACT

Under screenhouse conditions, the experiment was carried out to evaluate the efficacy of four insect growth regulators viz. ,lufenuron at 25,12.5, and 6.25ppm, pyriproxyfen at 25,12.5 and 6.25ppm, spirotetramat at 50,25 and 12.5 ppm and methoxyfenozide at 120,60, and 30 ppm in biocontrolling root- knot nematode, Meloidogyne incognita infecting eggplant (Solanum melongena L.) cv. Baladi i.e. at the recommended and other two lower concentrations. The tested materials at the highest concentrations were more effective in reducing nematode criteria than the other concentrations compared to untreated control. The moderate and highest concentrations of methoxyfenozide caused the highest percentages of reduction in nematode final population (81.36 and 81.06% respectively) followed by lufeuron, pyriproxyfen and spirotetramat. Plant growth was improved, spirotetramat achieved the highest percentages of increases of root and shoot dry weights.
