Abstract

Efficacy of novel nematicide, imicyafos GR was evaluated against two species of the root-knot nematodes in pot and greenhouse conditions. When tested in pots, the population of Meloidogyne incognita and M. hapla was reduced sixty days after treatment, with mortality rate of 91.5% and 90.6%, respectively. Suppression effect of imicyafos GR on root galling in tomato was tested. The number of root galls caused by M. incognita and M. hapla was reduced 60 days after nematode inoculation, with the efficacy of 94.2% and 95.1%, respectively. Under greenhouse conditions planted with watermelon, melon, cucumber, and tomato, the efficacy of imicyafos GR on M. incognita persisted up to 60 days after treatment, showing 90% of control efficacy. Moreover, the number of root galling was more reduced than fosthiazate treatment, with the potential as a control agent.

살선충제인 imicyafos 입제 처리에 따른 방제효과를 알아보기 위하여 고구마뿌리혹선충과 당근뿌리혹선충을 대상으로 포트시험과 포장시험을 수행하였다. 포트시험 결과 imicyafos 입제 처리 60일 후 생충수와 난낭수 조사에서 고구마뿌리혹선충은 91.5%, 94.2%, 당근뿌리혹선충은 90.6%, 95.1%로 각각 높은 방제 효과를 나타내었다. 시설재배 수박, 참외, 멜론, 오이, 토마토에서 imicyafos 입제를 처리하여 방제효과를 조사한 결과 고구마뿌리혹선충에 대하여 imicyafos 입제는 처리 후 30일째와 60일째 까지 90% 이상의 방제가를 나타내었으며, 약효의 지속성도 뛰어났다. 특히 imicyafos 입제를 처리가 fosthiazate 입제 처리 보다 난낭수 형성을 더 억제하는 것으로 나타났다. 따라서 살선충제인 imicyafos 입제는 고구마뿌리혹선충이나 당근뿌리혹선충 방제에 실용성이 있을 것으로 판단된다.
