Abstract:
PURPOSE: A composition for preventing tabacco masaic disease and Botrytis cinerea using L-pyroglutamate is provided to produce organic agricultural products without environmental pollution. CONSTITUTION: A composition for preventing tabacco masaic disease and Botrytis cinerea contains 0.01-15 weight% of butyl L-pyroglutamate of chemical formula 1 as an active ingredient. The butyl L-pyroglutamate of chemical formula is obtained from Klepsiella oxytoca C1036(deposit number KACC 91265P).
Abstract:
PURPOSE: A composition of an agent for inducing plant disease resistance, containing butyl L-pyroglutamate is provided to has resistance to plant disease and enhance productivity of crop. CONSTITUTION: A composition of an agent for inducing plant disease resistance contains butyl L-pyroglutamate of chemical formula 1 as an active ingredient. The butyl L-pyroglutamate is obtained from Klepsiella oxytoca strain(deposit number KACC 91265P). A method for isolating butyl L-pyroglutamate comprises: a step of extracting culture medium of Klepsiella oxytoca C1036 strain(deposit number KACC 91265P) with ethyl acetate; a step of extracting obtained aqueous solution layer with butanol at pH 2.0~4.5; and a step of performing ODS column chromatography, solid phase extraction and high speed liquid chromatography. The plant disease is Pectobacterium carotovorum subsp. carotovorum SCC1-mediated disease.
Abstract:
본 발명은 하기 화학식 1의 부틸 L-피로글루타메이트(Butyl L-pyroglutamate)를 유효성분으로 함유하는 식물병 저항성 유도제 조성물 및 이를 이용한 식물병 저항성 유도방법에 관한 것이다. 상기 부틸 L-피로글루타메이트는 크랩시엘라 옥시토카 C1036 ( Klepsiella
oxytoca C1036)으로부터 유래되는 것으로, 식물병에 대한 저항성을 유도하는 역할을 한다. [화학식 1]
