草甘膦是灭生性除草剂。使用时采用防护措施定向喷施,就能达到有选择地灭除杂草而对作物安全的目的。以一年生杂草为主的地块和蔗田,每亩用草甘膦0.75公斤,兑水30公斤;以多年生杂草为主的地块和蔗田,每亩用1.5公斤,均匀喷药一次,待杂草枯黄或死亡后,不再整地,即可直接开沟或挖穴种蔗,防治效果达95%左右,并对甘蔗发芽生长没有不良影响。苗期用防护装置定向喷洒草甘膦,每亩分别用0.5公斤和1.25公斤,兑水30公斤,对防治一年生和多年生杂草效果达90～95%。用草甘膦进行甘蔗植前化学整地和苗期杂草防除,能及时消灭杂草,省工、省时、省钱,社会经济效益十分显著。
Glyphosate is a biocidal herbicide. The use of protective measures directed spraying, we can achieve the selective removal of weeds and crop safety purposes. With annual weeds dominated plots and cane fields, with glyphosate 0.75 kg per mu, watered 30 kg; perennial weeds mainly plots and cane fields, with 1.5 kg per mu, spray evenly once , After the weeds are yellowish or dead, no more soil will be dug or dug the cane directly. The control effect is about 95%, and there is no adverse effect on the germination and growth of sugarcane. Seedlings with protective devices directional spraying of glyphosate, respectively, with 0.5 kg and 1.25 kg per mu, watered 30 kg, on the prevention and treatment of annual and perennial weeds 90 ~ 95%. With glyphosate sugarcane planting chemical pre-plantation and seedling weed control, weeds can be eliminated in time, labor-saving, time-saving and economical, social and economic benefits are significant.
