Abstract
Pot experiment was conducted containing powder of dried leaves of Guaicum officinale L., Sapindus trifoliatus L. or Barleria acanthoides Vahl. in soil in combination with three Bacillus thuringiensis Berliner isolates viz. B.t.-64, B.t.-16 or B.t.-14 to observe their efficacy on growth and root knot nematode Meloidogyne javanica associated with roots of okra. Leaf powder was applied in soil at the rate of 1 % w/w and bacterial cell suspension was inoculated around the roots after 10 days of growth of seedlings. The combination of Bt-64 and 1% w/w leaf powder of S. trifoliatus was found to be the most effective treatment in reducing root-knot nematodes and improving growth in okra plants.
