Abstract:

【Objective】 In order to establish a safe and efficient herbicide application method in line with the current large-scale intensive planting background, the efficacy test and safety evaluation of fenoxaprop-P-ethyl with different application methods to control weeds in corn fields were carried out.【Methods】 Drip irrigation and plant protection UAV spraying were used to compare and analyze the actual control effect of water dripping and plant protection UAV ultra-low spraying herbicides on weeds in corn fields in Xinjiang irrigation area.【Results】 Compared with drip irrigation, spraying 6 % flumioxazinone OD 125 mL + 90 % atrazine 62.5 mL by drone had better control effect on Chenopodium glaucum, Abutilon theophrasti, Convolvulus arvense and Echinochloa crusgalli on the 5th, 10th and 15th day after treatment, but there was no significant difference on the 30 th day.The study also found that the application of herbicides under mulched drip irrigation was significantly better than that without mulched drip irrigation, and the plant control effect and fresh weight control effect of the application of herbicides under mulched drip irrigation were 98.48 %-100 % and 99.28 %-100 %, respectively, after 30 days of treatment.The plant control effect and fresh weight control effect were only 71.60 % and 74.28 %, respectively, after 30 days of treatment of Convolvulus arvensis.In addition, different application methods did not produce obvious phytotoxicity symptoms on maize, and the yield of maize was significantly improved.【Conclusion】 Drip application of flumioxazinone herbicide can be applied to control a variety of weeds in irrigated maize production areas in Xinjiang.

摘要:

【目的】不同设置苯唑氟草酮施药方式防除玉米田间杂草的药效试验,并进行安全性评价,筛选符合当前大面积集约化种植的高效除草剂安全施药方法。【方法】采用滴灌施药及植保无人机喷施的方式,对比分析随水滴施和植保无人机超低量喷施除草剂对新疆灌区玉米田杂草的实际防除效果。【结果】相较于滴灌滴施,利用无人机喷施6%苯唑氟草酮可分散油悬浮剂(OD) 125 mL+90%莠去津62.5 mL在药后第5、10和15 d对灰藜、苘麻、田旋花及稗草的防效更优,施药30d时两者间无显著差异。膜下滴灌滴施除草剂显著优于无膜滴灌滴施处理,且膜下滴灌施药对灰黎、苘麻和稗草药后30 d的株防效和鲜重防效依次为98.48%~100%和99.28%~100%,对田旋花药后30 d的株防效和鲜重防效分别仅为71.60%和74.28%。此外,不同施药方式均未对玉米产生明显的药害症状,且对玉米产量有显著提升。【结论】滴施苯唑氟草酮除草剂可应用于新疆灌溉玉米产区防治多种杂草。
