There is also difference, Chinese weeds in paddy field types about more than 200, wherein serious common weed of causing harm has more than 20 for environment variety classes
Kind, largely belong to angiosperm, including monocotyledon and dicotyledon, minority is fern and algae, Pesticide Science
In we be frequently referred to grass family, Cyperaceae and broadleaf weeds.
Paddy field weeding is always the managerial problem of Rice Cropping, because Weed infestation can to crop caused by the underproduction as a result,
Means most effective, economic at present are exactly chemical weed control, but use single variety or single effect machine to continuous high dose for a long time
The herbicide of reason causes weeds drug resistance and drug resistance constantly to enhance, and weed control is more and more difficult.And it is removed different types of
Careless agent, which is rationally compounded or used with, can effectively expand degrass spectrum, improve preventive effect, delay weeds drug resistance and drug resistance, be solution
Certainly above-mentioned one of the most efficient method for preventing and kill off difficult problem.
