Management of Meloidogyne incognita on tomato with different biocontrol organisms

Abstract

The effect of biocontrol agents comprising Bacillus sp., and Streptomyces rubrogriseus on the management of the root-knot nematode Meloidogyne icognita was investigated along with a nematicide Fosthiazate on tomato susceptible cultivar cv. Baiguoqiangfeng. The S. rubrogriseus culture filtrates (CF) showed maximum mortality of second stage juvenile (J2) followed by Bacillus sp., at 12 h and 24 h duration of exposure time as compared to the control treatment containing medium (L.B). In the green house experiments Fosthiazate had significant increased the root length, shoot length and reduced the number of root-knot nematode galls on tomato roots followed by biocontrol agent S. rubrogriseus and Bacillus sp., as compared to the untreated control treatment after 60 DPI and 90 DPI
