Abstract

Potassium phosphonate inhibited less mycelial growth of Phytophthora cactorum in vitro than metalaxyl-M. But the net protection rate in leaflet test and whole plant pot test was greater in potassium phosphonate than metalaxyl-M. P. ginseng appeared to have an induced resistance against P. cactorum with phosphonate around 50~100 ppm.

아인산의 농도별 (50~2,000 ppm) 인삼 역병 방제효과를 metalaxyl-M (a.i. 40.2 ppm)과 비교하여 역병균의 균사생장에 대한 영향, 인삼 절제엽과 포트시험으로 검토하였다. 아인산은 균사생장억제력이 metalaxyl-M 보다 낮았으나 절제엽이나 식물전체 실험에서는 metalaxyl-M 보다 방제효과가 우수하여 인삼에서 병저항성을 유도하는 것으로 보였으며, 50~100 ppm의 아인산이 병저항성을 유도하는 적정농도일것으로 생각된다.
