Abstract

This study was conducted to investigate the herbicidal efficacy of up granule formula of benzobicyclon mixtures, benzobicyclon + azimsulfuron + oxaziclomefone up granule (BAO UG) and benzobicyclon + bensulfuron-methyl + fentrazamide up granule (BBF UG) to control annual and perennial weed species in a rice paddy field. Four annual weed species including Echinochloa crus-galli L. and three perennial weeds were dominated in the experimental field. Application of BAO UG and BBF UG was highly effective to control both annual and perennial weed species. No phytotoxic effect was observed in the rice based on the plant height, the number of tillers, and culm and panicle length. Finally, rice yield in the BAO UG and BBF UG treatment was as much as that in the hand weeding. This study indicates that self-dispersible floating formula of benzobicyclon mixtures can be applied to control both annual and perennial weed species in rice paddy fields and contribute to save labor costs.

본 시험은 벼 어린모 기계이앙 답에서 발생하는 일년생 잡초와 다년생잡초에 대한 방제효과를 알아보기 위하여 benzobicyclon을 기반으로 한 수면부상성 입제로 개발한 BAO UG와 BBF UG의 방제효과를 BIF SC와 비교하여 실험을 수행하였다. 시험약제인 BAO UG와 BBF UG의 잡초방제효과는 96% 이상으로 높게 나타났으며 벼에 대한 안전성이 높은 것으로 나타났다. 또한 후기생육 및 수확량에 있어서도 시험약제와 대조약제간에 차이가 없었으며 모두 벼에 대해 안전한 것으로 판단된다. 따라서 본 시험에서 사용한 수면부상성 입제의 경우 쉽게 처리할 수 있다는 장점이 있어 벼 생력재배를 위해 이용 가능 할 것으로 보인다.
