摘要: 【目的】研究添加助剂对精喹禾灵EC防除棉田禾本科杂草的增效作用,为除草剂减量施用和科学除草提供数据基础。【方法】通过温室盆栽和田间小区试验,在除草剂常规用量、减量20%和减量40%基础上添加助剂,比较精喹禾灵EC对马唐、牛筋草等禾本科杂草的防除效果。【结果】盆栽试验中,在推荐的常量用药水平下添加助剂Foxy SG和Fieldor Max EC,精喹禾灵EC对马唐和牛筋草2种禾本科杂草防效提高1.75%~5.78%,精喹禾灵EC减量20%和40%,2种助剂对防效的增效幅度分别为7.95%~10.54%和21.62%~41.63%,Fieldor Max EC的增效作用显著优于Foxy SG,精喹禾灵EC减量40%后添加Fieldor Max EC对禾本科杂草的防效与常量用药防效无显著差异;田间试验中,2种助剂对精喹禾灵EC的减量增效作用与盆栽试验结果相符,常量用药水平下添加Foxy SG和Fieldor Max EC,精喹禾灵EC对禾本科杂草株防效和鲜重防效提高0.83%~4.19%,精喹禾灵EC减量20%和40%,2种助剂对防效的增效幅度分别为1.08%~8.68%和12.06%~37.74%,Fieldor Max EC的增效作用显著优于Foxy SG,精喹禾灵EC减量40%后添加Fieldor Max EC对禾本科杂草的株防效与常量用药株防效无显著差异。【结论】Foxy SG和Fieldor Max EC 2种助剂,对棉田常用的选择性除草剂精喹禾灵EC除草活性有明显提高,减少除草剂使用量后加入助剂可解决防效降低问题,除草剂使用过程中加入高效助剂是实现除草剂减量增效的有效途径。

Abstract: 【Objective】 To study the synergistic effects of spraying adjuvants on control of gramineous weeds in cotton field in the hope of providing data basis for the application of herbicide scientifically. 【Method】With the pot and field experiments, the control effect of quizalofop-P-ethyl EC on the gramineous weeds such as Digitaria sanguinalis and Eleusine indica was compared by adding additives on the basis of conventional dosage, 20% reduction and 40% reduction.【Result】In the pot experiment, adding adjuvants Foxy SG and Fieldor Max EC under the conventional dosage, the fresh weight control of quizalofop-P-ethyl EC on Digitaria sanguinalis and Eleusine indica increased by 1.75%-5.78%, when the conventional dosage was reduced by 20% and 40%, the control effect of adding adjuvants increased by 7.95%-10.54% and 21.62%-41.63%, respectively. The synergism of Fieldor Max EC was significantly better than Foxy SG, and there was no significant difference between the control effect of adding Fieldor max EC and 40% reduction of conventional dosage. In the field experiment, the result was consistent with pot experiment. The control effect and fresh weight control effect of conventional dosage of quizalofop-P-ethyl EC were increased by 0.83%-4.19%, when Foxy SG and Fieldor Max EC added under conventional dosage and 20% reduction and 40% reduction of quizalofop-P-ethyl EC, the control effects were increased by 1.08%-8.68% and 12.06%-37.74%, respectively. The synergism of Fieldor Max EC was significantly better than that of Foxy SG, and there was no significant difference between the control effects of adding Fieldor max EC or 40% reduction.【Conclusion】The two kinds of adjuvants can significantly improve the herbicidal activity of the quizalofop-P-ethyl EC, and adding adjuvants can solve the problem of control effect decline after reducing the use amount of herbicides. Adding efficient adjuvants in the herbicides is an effective way to achieve the aim of reduction and synergism.
