LONG-ACTING MICROBIAL AGENT FOR CONTROLING MELOIDOGYNE SPP. IN PLANTS AND PREPARING METHOD THEREOF

摘要

In the present invention, the Bacillus subtilis and Streptomyces nigresense, which are the antagonists of the root-knot nematodes, are adsorbed on the porous carrier by persimmon powder and gelatin, and the persimmon extract, chul extract and marchi string extract are supported on the porous carrier and slowly in the soil. It relates to a sustained-release microbial agent for controlling root-knot nematodes characterized in that it is released, and a method for manufacturing the same, wherein the micro-organism agent adsorbs antagonistic bacteria against root-knot nematodes to a carrier, and supports an extract mixture having an insecticidal effect on a carrier to support root-knot nematodes As the mixed solution of antagonists and extracts for is slowly released, it is possible to improve control persistence as well as the control effect of excellent root-knot nematodes.
