稻田池埂和田间水渠杂草一般都生长茂盛,影响通风透光,而且还向田间蔓延,同时为害虫提供中间寄生,因此应尽早防除。池埂和水渠除草一般选用灭生性除草剂。一类是草甘膦类,主要品种有农达、可灵达、灵达、好利达、农旺、草甘膦粉剂等。草甘膦属于内吸传导型除草剂,植物吸收传导到根部杀死植物地下根茎;另一类是百草枯类,主要有克无踪、灭除等,而百草枯属于触杀型除草剂,只能杀死植株地上部分,不能杀死根茎,只能防除当年杂草。这两种药剂喷到水 Paddy field ponds and field drains weeds generally flourish, affecting the ventilation and transmissibility, but also spread to the field, while providing intermediate parasites for pests, it should be controlled as soon as possible. Ikegami and canal weeding generally use biocidal herbicides. One is glyphosate, the main varieties of Nongda, Ling Ling up, Lingda, good Leader, Nong Wang, glyphosate and other powder. Glyphosate is a systemic herbicide, which is absorbed by the plants and transmitted to the roots to kill the underground rhizomes. The other is paraquat, with no traces of trace and extermination. Paraquat belongs to the group of contact herbicides Can kill plants above the ground, can not kill rhizomes, can only control weeds. Both agents are sprayed onto the water
