落花生田禾本科雜草除草劑防除效果評估

Evaluation of Graminicides for Weed Control in Peanut Field

摘要


本試驗的目的在於評估萌後除草劑quizalofop-p-tefuryl噴施後對落花生田禾本科雜草的防除效果。試驗分二個栽培季節(2004年春作、2004年秋作)在雲林縣虎尾鎮及四湖鄉落花生栽培區進行。落花生田禾本科雜草於3至6葉齡時,以quizalofop-p-tefuryl 4.4%乳劑,每公頃0.75公升及1.5公升兩種施用量,進行全面均勻噴施,試驗期間對落花生植株均無藥害產生,對其生育、莢果產量亦無影響,而對落花生田常見的牛筋草(Eleusine indica (L.) Gaertn.)、芒稷(Echinochloa colona (L.) Link)及馬唐(Digitaria sanguinalis (L.) Scop.)等禾本科雜草的防除效果良好,但對闊葉雜草及莎草科雜草則無效果。綜合二個栽培季節試驗結果,並顧及農民經濟成本,落花生田可採用4.4% quizalofop-p-tefuryl EC每公頃施用量0.75公升,於落花生萌後早期施用,防除牛筋草等禾本科雜草。

並列摘要


Quizalofop-p-tefuryl was evaluated in screening tests for potential use in peanut field. This experiment was to evaluate quizalofop-p-tefuryl for peanut crop tolerance and post-emergence control of grass weed. Applying with quizalofop-p-tefuryl 4.4% EC at the concentration of 0.75 and 1.50 L/ha in peanut field, both exhibited good control effect on grass weeds such as Echinochloa colona, Eleusine indica, and Digitaria sanguinalis. In the post-emergence screening test, quizalofop-p-tefuryl gave acceptable weed control with adequate crop safety.
