Abstract
The binary compound herbicide as one kind of agricultural chemicals contains one kind of diphenyl ether herbicide, one kind of chloroacetamide herbicide and assistant. It has the advantages of both diphenyl ether herbicide and chloroacetamide herbicide, their synergistic and cooperative effect, wide herbicidal spectrum and raised herbicidal effect. Once application can ensure no weed damage in the whole growth period of crop. It has high safety to water melon. It has low cost, convenient use, less residue and environmental pollution.
Description
Technical field
The invention provides a kind of agricultural chemicals, especially a kind of weed killer herbicide.
Technical background
At present, weed killer herbicide is single in particular for the weed killer herbicide active ingredient of watermelon soil treatment, does not reach the double purpose of removing of grass family and broadleaved herb.After spraying the weed killer herbicide of amide-type separately, broadleaved herb is still grown thickly; After spraying the weed killer herbicide of diphenyl ether separately, weeds gramineous are normal growth still, and consumption easily causes the watermelon poisoning when big, causes the underproduction.
Summary of the invention
Technical problem to be solved by this invention is, a kind of binary compound herbicide is provided, and it can prevent and kill off grass family and broad leaved weed simultaneously.
The present invention is achieved in that a kind of binary compound herbicide, and described weed killer herbicide contains any one in any one and the former medicine of chloroacetyl amine weed killer herbicide in the former medicine of diphenyl ether herbicide, percentage meter by weight, and its proportioning is:
The former medicine 5.0-60.0% of chloroacetyl amine weed killer herbicide
The former medicine 2.0-20.0% of diphenyl ether herbicide
Auxiliary agent 20.0-93.0%
This binary compound herbicide combines the advantage of chloroacetyl amine, diphenyl ether herbicide, have collaborative and synergistic effect, enlarged and killed the grass spectrum, improved herbicidal effect, remedied the defective of single agent to the anti-heterodyne of main weeds, a drug can ensure that whole growing is not endangered by weeds.Safe to watermelon, manufacture method is simple, and is with low cost, easy to use, reduced residual big, the easy weed killer herbicide consumption of contaminated environment, protected environment.
