Penoxsulam의 제초활성 및 Sulfonlyurea계 제초제 저항성잡초 방제를 위한 혼합제 연구 = Herbicidal Efficacy of Penoxsulam and its Mixture Herbicide Development for Controlling Sulfonylurea Herbicide-Resistant Weeds

다국어 초록 (Multilingual Abstract)

Herbicidal efficacy of penoxsulam by formulation type and application timing of penoxsulam and the development of its mixture herbicides for controlling sulfonylurea herbicide-resistant weeds were studied to develop weed control system using penoxsulam in direct water-seeded rice paddy field.
1. Emulsified concentrate (EC), suspension concentrate (SC) of 0.6% and 3% and granular formulation of penoxsulam provided better control of Echinochloa crus-galli, but control of Ludwigia prostrata and Eleocharis kuroguwai was poor than that of pyrazosulfuron-ethyl granule.
2. Echinochloa crusgalli and Monochoria vaginalis were controlled by penoxsulam EC treatment before direct water-seeding of rice, but control of Ludwigia prostrata was poor. Standing of rice was slightly low due to phytotoxicity by penoxsulam.
3. Foliar application of penoxsulam at 30 days after direct water-seeding of rice provided good control of most paddy weeds except of Ludwigia prostrata. However, weed control efficacy of penoxsulam were very poor by foliar application of penoxsulam at 45, and 60 days after rice direct-seeding. Foliar application of penoxsulam provided no control of sulfonylurea herbicide-resistant Monochoria vaginalis and showed no phytotoxicity of rice.
4. Thiobencarb GR, mefenacet SC, fentrazamide GR, and simetryn GR provided good control of sulfonylurea herbicide-resistant Monochoria vaginalis and 4 mixture herbicides of penoxsulam with thiobencarb, mefenacet, fentrazamide, and simetryn controlled Echinochloa crus-galli and sulfonylurea herbicide-resistant Monochoria vaginalis as well as wild Monochoria vaginalis by the treatment at 10 and 15 days after rice transplanting.
5. There was no phytotoxicity of rice by penoxsulam + thiobencarb, but penoxsulam+mefenacet and penoxsulam+fentrazamide showed mild phytotoxicity and rice growth was greatly inhibited by penoxsulam + simetryn due to severe injury of rice.
