杀草丹又叫稻草完,化学名称为S—(4—氯苄基)—N、N—二乙基硫代氨基甲酸酯,国外名称为Saturn、Benthiocarb、Bolero,在日本是一个大规模生产的除草剂,年产原药六千吨,是当前日本防除水稻杂草用量较大的品种。几年来;从国内大面积的施用,也取得了显著效果。 杀草丹对人、畜、鱼毒性低,是选择性内吸除草剂,杀草丹可以被发芽种子和根部吸收,然后随蒸腾流向地上部传导,产生药效。杀草丹的防除作用主要在于抑制α—淀粉酶的生物合成过程,使发芽植物种子中淀粉的水解减弱
Sclerotium also known as straw finished, the chemical name is S- (4-chlorobenzyl) -N, N-diethyl thiocarbamate, a foreign name for Saturn, Benthiocarb, Bolero, in Japan is a large-scale Production of herbicides, with an annual output of raw materials six thousand tons, is Japan’s current control of rice weeds larger varieties. In recent years, the large-scale application from China has also achieved remarkable results. Dancao Dan on humans, livestock, fish, low toxicity, is a selective systemic herbicide, herbicide Dan can be germinated seeds and root absorption, and then with the transpiration flow to the upper part of the conduction, resulting in efficacy. Control of herbicide Dan is mainly to inhibit the α-amylase biosynthesis process, so that the germination of plant starch hydrolysis is weakened
