摘要: 为了解960 g/L精异丙甲草胺乳油防除番茄田杂草的效果及安全性,以川科8号番茄为试材,采用田间小区试验研究了960 g/L精异丙甲草胺乳油对番茄田一年生禾本科杂草和部分阔叶杂草的防除效果及其安全性。结果表明,该960 g/L精异丙甲草胺乳油在番茄移栽前1~2 d土壤喷雾处理,对番茄田一年生禾本科杂草马唐[Digitaria sanguinalis (L.) Scop.]、光头稗[Echinochloa colonum (L.) Link.]及部分阔叶杂草草龙[Ludwigia hyssopifolia (G.Don)Exell]、凹头苋(Amaranthus lividus L.)和异型莎草(Cyperus difformis L.)防效较好,推荐剂量(制剂量)为750.0~862.5 mL/hm2[720~828 (a.i.)g/hm2]。960 g/L精异丙甲草胺乳油对番茄田常见一年生禾本科杂草和部分阔叶杂草防效较好;但由于施药后当天下雨,导致药剂处理区番茄株高受到一定抑制,植株矮化,并造成不同程度减产。

Abstract: In order to underatand controlling effect and safety of 960 g/L metolachlor EC against weeds in tomato fields. Tomato variety of Chuanke No.8 was used as experimental materials,control effect and safety of 960 g/L metolachlor EC against annual grass weeds and some broadleaf weeds in tomato fields was studied by field plot test. The results showed that the control effect against Digitaria sanguinalis (L.) Scop., Echinochloa colonum (L.) Link., Ludwigia hyssopifolia (G.Don)Exell, Amaranthus lividus L., Cyperus difformis L. was excellent by soil spray treatment, 1~2 days before tomato transplanting. The recommended dose (formulation amount) was 750.0~862.5 mL/hm2[720~828 (a.i.)g/hm2]. Control effect of 960 g/L metolachlor EC against common annual grass weeds and some broadleaf weeds in tomato fields was excellent. However, due to the rain on the day after spraying, the tomato plant heights in the treatment areas were inhibited to some extent, and the plants were dwarfed, resulting in different degrees of yield reduction.

Key words: metolachlor, tomato, weed, control effect, safety
