10%单嘧磺隆WP单剂对谷田杂草防效及对谷子安全性研究
|
摘要
为研究单嘧磺隆对谷田杂草防效及对谷子的安全性,通过田间药效试验,测定10%单嘧磺隆WP与对照药剂扑草净对谷田杂草的防效和对谷子产量的影响,并评价了其安全性。结果显示,于春谷子播后苗前施药,10%单嘧磺隆WP对谷田阔叶杂草和马唐具有非常高的防除效果,而对牛筋草在规定使用剂量下,效果较差,但倍量使用效果较好,且对谷子安全,相对人工除草,产量无差异;对照药剂40%扑草净持效期较短,施药42天后到收获期,阔叶杂草少量发生,马唐大量发生且影响产量。
In order to study the effects of monosulfuron on weed control and its safety to millet, we determined the effects of 10 % monosulfuron WP and prometryne on weed control and millet yield by field efficacy test, and evaluated their safety. Results showed that 10 %monosulfuron WP had the best control effect on broadleaf weed and crabgrass in millet field before seedling after sowing in spring, and it was safe to millet, and the millet yield had no difference compared with that by manual weeding; but the prescribed dosage had poor effect on goosegrass, only multiple dosage had better effect. The control insecticide, 40% prometryne had a short effective period,broadleaf weed and crabgrass began to grow after 42 d, leading to a reduction in millet yield.
