MICROORGANISM, BACILLUS SUBTILIS HN12, INHIBITING GROWTH OF CYLINDROCARPON DESTRUCTANS AND METHOD AND COMPOSITION FOR PROTECTING RUST OF PLANT ROOTS USING THE SAME

摘要

PURPOSE: A microorganism, Bacillus subtilis HN12, inhibiting the growth of Cylindrocarpon destructans and a method and composition for protecting the rust of plant roots using the same are provided, thereby inhibiting the rust of plant roots without toxicity. Therefore, repeated cultivation of ginseng can be carried out. CONSTITUTION: The microorganism, Bacillus subtilis HN12(KCCM 10481), inhibiting the growth of Cylindrocarpon destructans is provided, wherein Bacillus subtilis HN12(KCCM 10481) is isolated from the soil. The method for protecting the rust of plant roots comprises spraying the cultured medium of Bacillus subtilis HN12(KCCM 10481) into the plant roots or the surrounding soil thereof, wherein the cultured medium of Bacillus subtilis HN12(KCCM 10481) contains 400000 to 400000000 cfu/ml. The composition for protecting the rust of plant roots comprises Bacillus subtilis HN12(KCCM 10481).
