杀草丹(Benthiocab)是日本组合化学工业公司1968年研制成的一个优良除草剂。主要用于防除水田杂草,效果优于敌稗和除草醚,也可用于麦田、豆田等旱田作物。现已发展成为水田主要除草剂,是硫代氨基甲酸酯类除草剂中生产量最大的品种,已在40多个国家登记注册。 杀草丹化学名:S—(4—氯苯基)N,N—二乙基硫赶氨基甲酸酯。纯品为无色,工业品为黄色液体。熔点3.3℃,沸点126—129℃/0.008毫米汞柱,比重1.16(20℃/4℃)。难溶于水,20℃时,在水中仅溶解30ppm,可溶于苯、甲苯、酒精等有机溶剂。对酸碱稳定。 据各地试验结果表明,杀草丹具有下列优点。 高效、适应性广:杀草丹为内吸传导型,对稗草、牛毛毡、松草蔺、莎草等一年生禾本科和莎草科杂草极为有效,并且对其它一年生阔叶杂草也有效。杀草丹有较强的土壤吸附性,所以适用于沙土、壤土等多种土壤。
Benthiocab is an excellent herbicide developed by the Japan Chemical Industry Corporation in 1968. Mainly used to control weeds in paddy field, the effect is superior to propanil and weed ether, can also be used for wheat fields, bean fields and other dry crops. Has now become the major herbicide in the paddy field and is the most productive variety of thiocarbamate herbicides registered in more than 40 countries. Sulfatide Chemical Name: S- (4-chlorophenyl) N, N-diethylthiocarbamate. Pure product is colorless, industrial products for the yellow liquid. Melting point 3.3 ℃, the boiling point of 126-129 ℃ / 0.008 mm Hg, the proportion of 1.16 (20 ℃ / 4 ℃). Insoluble in water, 20 ℃, only 30ppm dissolved in water, soluble in benzene, toluene, alcohol and other organic solvents. Acid and alkali stability. According to the test results around show that kill grass Dan has the following advantages. Efficient, wide adaptability: kill grass Dan for the absorption conduction type, the barnyard grass, cattle blankets, pine grass, sedge and other annual grass and sedge weeds extremely effective, and other annual broadleaf weeds also effective. Killer grass Dan has a strong soil adsorption, it is suitable for sand, loam and other soil.
