SCLEROTIUM DELPHINII BWC04-107 HAVING WEEDING EFFICACY AGAINST PARAQUAT RESISTANCE CONYZA AND MYCELIA SUSPENSION PREPARED USING THIS

摘要

A microorganism Sclerotium delphinii BWC04-107 having control efficacy against paraquat-resistant conyza and the mycelium suspension prepared by using the same microorganism are provided to specifically control the paraquat-resistant conyza through living as a host specific parasite in the paraquat-resistant conyza in an environment-friendly manner. A microorganism Sclerotium delphinii BWC04-107(KACC 93031P) has control activity against paraquat-resistant conyza as well as mugworts, sola, clover and iris. A mycelium suspension is prepared by culturing Sclerotium delphinii BWC04-107(KACC 93031P) in PD broth medium at 25-28 deg.C, pH 5-6 and 150rpm for 5-7 days and pulverizing a semisolid mycelium clot formed by the culture.
