초록
벼 담수직파시 제초제에 의한 약해의 원인을 구명하고자 온도, 용액의 pH, 수심, 토성 및 영양(營養)의 유무(有無) 등의 조건하에서 실험을 실시한 결과는 다음과 같다. 1. Bensulfuron methyl 및 pyrazosulfuron-ethyl 처리는 20/
This experiment was conducted to investigate the factor of phytotoxicity for herbicides(bensulfuron methyl, pyrazosulfuron-ethyl, dimepiperate, molinate) on flood direct-seeded rice. The phytotoxicity of herbicides was evaluated under controlled environment condition. Bensulfuron methyl and pyrazosulfuron-ethyl reduced more rice growth, especially root growth on low temperature(20/
