摘要: 【目的】研究除草剂中添加喷雾助剂对其减量增效影响,为减少田间除草剂用量提供理论支撑。【方法】采用田间小区试验,土壤处理除草剂50%丙炔氟草胺WP和33%二甲戊灵EC的用量分别减少20%、30%后,分别添加激健、安融乐、迈丝、增效王等4种喷雾助剂,与常规用量除草剂比较效果和安全性。【结果】除草剂用量减少20%和30%后分别添加4种喷雾助剂对棉花安全。施药后第30 d,除草剂减量20%、30%后分别添加4种喷雾助剂的处理对杂草的防效显著低于常规剂量处理。施药后第45 d,除草剂减量20%、30%后添加4种喷雾助剂对杂草的防效与常规剂量处理无显著差异。施药后第60 d,除草剂减量20%后分别添加激健、安融乐、增效王等处理对杂草的防效与常规剂量处理无显著差异,除草剂减量30%后添加4种喷雾助剂对杂草的防除效果比常规剂量差,常规剂量处理对杂草的防效为90.08%。除草剂减量20%后添加4种喷雾助剂对杂草的鲜质量防效在98.2%以上,高于常规用量。【结论】除草剂50%丙炔氟草胺WP和33%二甲戊灵EC用量减量20%后添加激健、安融乐、增效王等3种喷雾助剂对棉田杂草防除效果与常规用量相当,且对棉花生长发育安全。

Abstract: 【Objective】 To study the reduction and synergistic effects of spray-adjuvants on herbicide, in the hope of providing theoretical support for reducing the dosage of herbicide in the field.【Method】 Field plot experiments were conducted to reduce the amount of soil-applied herbicides 50% Flumioxazin WP and 33% Pendimethalin EC by 20% and 30% respectively, and then 4 kinds of spray-adjuvants such as Jijian, Anrongle, Maisi and Zengxiaowang were added to compare the control effects on weed and safety of cotton with the treatments of conventional dosage.【Result】 It was safe for cotton growth that the dosage of herbicide was reduced by 20% and 30% respectively and then 4 kinds of spray-adjuvants were added. On 30 days after application of herbicide, adding 4 kinds of spray-adjuvants respectively after the dosage of herbicide was reduced 20% and 30%, the control effect on weeds was significantly lower than the conventional dosage. On 45 days after application of herbicide, there was no significant difference in weed control effect between the conventional dosage treatment and the treatments whose dosage of herbicide was reduced by 20% and 30% respectively with 4 kinds of spray-adjuvants added. On 60 days after application of herbicide, there was no significant difference in weed control effect between the conventional dosage treatment and the treatments whose dosage of herbicide was reduced by 20% with Jijian, Anrongle and Zengxiaowang added. The control effect was worse than the conventional dosage when the dosage of herbicide was reduced by 30% with 4 kinds of spray-adjuvants added. The control effect of the conventional dosage was 90.08%. The fresh weight control effect of the dosage of herbicide reduced by 20% and added 4 kinds of spray-adjuvants were more than 98.2%, which was higher than the conventional dosage.【Conclusion】 The dosage of 50% Flumioxazin WP and 33% Pendimethalin EC are reduced by 20% and then Jijian, Anrongle and Zengxiaowang added, it is found that its control effect of weeds in cotton field is equivalent to the conventional dosage, and they are safe for cotton growth. The results remain to be studied before application in the vast fields.
