除草剂在现代农业中越来越显示其重要作用,但在实践中发现:有些除草剂在土壤中的残效期过长,危及后茬作物;有些高效除草剂品种,因选择性限制,无法在敏感作物田中使用(如在禾本科作物田中防禾本科杂草);有时还会出现因使用不当、用量过多或误用等情况而造成药害。为了解这些问题,农药化学家们发明了一类新药剂——除草剂安全剂。 早在1947年,有人就发现了在蕃茄上2、4、6——T对2、
Herbicides have increasingly shown their important role in modern agriculture. However, in practice, some herbicides have been found to have too long residual life in soils that are endangering stubble crops. Some highly effective herbicide varieties are not sensitive due to selective restrictions Crop field use (such as grasses in the field of grass-weed prevention); sometimes there may be due to improper use, excessive use or misuse of the resulting injury. To understand these issues, pesticide chemists invented a new class of agents - herbicide safeners. As early as 1947, it was discovered that 2,4,6-T on tomatoes 2,
