中文摘要 | 落花生田於禾本科雜草3至6葉時,以每公頃用量0.8公升及1.0公升且稀釋至每公頃600公升水量的25%剋草同(Clethodim)EC殺草劑施用,落花生無藥害產生,其發芽及生育、產量均不影響,對牛筋草、狗牙根、畫眉草、大指草、稗等禾本科雜草防除效果均為良好,試驗藥劑為一選擇性殺草劑,僅對禾本科雜草防除有效,對闊葉雜草則無效果。綜合台南、台中及花蓮等三場試驗結果,並顧及農民經濟成本,落花生田以推薦採用25%剋草同(Clethodim)EC每公頃用量0.8公升為宜。 |
英文摘要 | Postemergence herbicide, 25% Clethodim EC, was applied to grasses of three-to-six-leaf stage in peanuts (Arachis hypogaea L.). There was no herbicide damage found in peanut. Clethodim at 0.8 and 1.0 l/ha (each diluted to 600 l/ha) provided excellent grass weed control. This herbicide was significantly and effectively controlled goose grass (Eleusine indica Gaertn), Bermuda grass (Cynodon dactylon Pers.), Niwahokori grass (Eragrostis Niwahokori Honda), Inu-mehisiba (Digitaria microbachne Presl. Henr.) and barnyard grass (Echinochloa crus-galli Beauv. var. formosensis ohwi.). Clethodim were not effective in broad leaf weed control. Peanut leaves and stems were not affected and yields of peanut were usually higher by applying Clethodim at 0.8 l/ha. Based on trials of Tainan, Taichung, and Hualien District Agricultural Improvement Station, we recommend the use of 25% Clethodim, at 0.8 l/ha and diluted with 600 l/ha of water, for effective and economic grass control. |
