- 摘要:
- 为探讨75%苯磺隆水分散粒剂对春小麦田一年生阔叶杂草的防除效果和对春小麦的安全性,该研究进行了田间小区试验。结果表明:75%苯磺隆水分散粒剂在春小麦使用的适宜的施药时期为小麦苗后4~5叶期,一年生阔叶杂草株高不超过5 cm;推荐有效成分用量为18.0~22.5 g·hm-2,在推荐剂量范围内对供试的春小麦安全。施药后30 d,对一年生阔叶杂草的合计株防效为95.9%~99.2%,鲜重防效为97.6%~99.7%。
- Abstract:
- In order to discuss the control efficacy and safety of 75% tribenuron-methyl WDG on annual broadleaf weeds in spring wheat field,field plot trials were conducted.The results showed that the suitable application period of 75% tribenuron-methyl WDG was 4~5 leaf stage of spring wheat seedling and the height of annual broadleaf weeds was below 5 cm,the appropriate amount of effective ingredients was 18.0~22.5 g·hm-2,it was safety in recommended dose for spring wheat.The total control efficacy on annual broadleaf weeds was 95.9%~99.2% and control effect of fresh weight was 97.6%~99.7% after 30 d for applying .
