摘要:

为有效防除节节麦和1年生阔叶杂草的危害,筛选具有较好控制作用的除草剂,笔者开展3%世玛油悬浮剂与3%双氟磺草胺·唑草酮悬浮剂混配防除冬小麦田恶性杂草田间药效试验。试验表明,小麦返青期进行茎叶喷雾施药,药后30天对婆婆纳、播娘蒿、猪秧秧和荠菜株防效可达50.0%~72.5%,药后45天对婆婆纳、播娘蒿、猪秧秧和荠菜鲜株防效可达67.2%~95.8%,对节节麦鲜株防效可达81.3%。说明3%世玛油悬浮剂与3%双氟磺草胺·唑草酮悬浮剂混配可有效防除节节麦和1年生阔叶杂草,能够达到小麦返青后的最佳除草效果。同时田间调查显示该混配对小麦安全。

Abstract:

The paper aims to effectively control the hazards of Triticum aestivum and 1-year-old broad-leaved weeds, and screen herbicides with good control efficacy. We conducted field trials on the control of weeds in winter wheat field by mixing 3% Sigma oil suspension concentrate and 3% Fluperazine and Butachl suspension concentrate. The results showed that: 30 d after spraying on wheat leaves at returning green stage, the control effect on Veronica didyma Tenore, Descurainia sophia (Linn.) Webb ex Prantl, Galium aparine Linn. var. tenerum Gren.et Godr. Rebb. and Capsella bursa-pastoris (L.) Medic. reached 50.0%-72.5%; 45 d after the treatment, the control effect on the fresh weight of Veronica didyma Tenore, Descurainia sophia (Linn.) Webb ex Prantl, Galium aparine Linn. var. tenerum Gren.et Godr. Rebb. and Capsella bursa-pastoris (L.) Medic. reached 67.2%-95.8%, and the control effect on the fresh quality of Aegilops tauschii Coss. was up to 81.3%. The results indicate that the mixture of 3% Sigma oil suspension concentrate and 3% Fluperazine and Butachl suspension concentrate could effectively control Aegilops tauschii Coss. and 1-year-old broad-leaved weeds, and could achieve the best weed control effect after wheat returning green, at the same time, the field investigation shows the mixture is safe for wheat.

Key words: Sigma, Florasulam and Triazolone, winter wheat, Aegilops tauschii Coss., broad-leaved weeds, efficacy evaluation
