Description
Technical field
The present invention relates to the composition pesticides of a kind of containing chlorine fluorine pyridine ester and ethoxysulfuron, belong to technical field of pesticide.
Background technique
Chlorine fluorine pyridine ester (florpyrauxifen-benzyl) is the novel aromatic base pyrrole of The Dow Agrosciences, LLC.'s exploitation
Pyridine first acid herbicides can be applied to rice direct seeding field, transplant field and other the crop fields.The CAS accession number of chlorine fluorine pyridine ester is
1390661-72-9 can effectively prevent and kill off the main gramineae weed of paddy field, broadleaf weeds and nutgrass flatsedge with extensive degrass spectrum
Section weeds.
Ethoxysulfuron, other title ethoxysulfurons, Sunstar, chemical name: 1- (4,6- dimethoxypyridin -2-
Base) -3- (2- phenoxy ethoxy sulfonyl) urea, have the characteristics that the application phase is wide, easy to use and safety is good.Ethoxysulfuron
Belong to sulfonylurea interior suction selectivity soil and foliar herbicide, prevents and kill off rice field broadleaf weeds and nutgrass flatsedge, the mechanism of action is to pass through
Weeds root and cauline leaf are transmitted in plant after absorbing, and prevent Amino acid synthesis, and inhibit growth and the root of weeds cauline leaf rapidly
Portion's elongation, it is completely withered to finally result in weeds.Ethoxysulfuron speed of action is slower, starts to inhibit to grow after general medication, 5-7 days
Can be seen that poisoning symptom, but weeds death takes 7-15 days or so, drug will slowly be transmitted to root by weeds photosynthesis,
Butt rot is caused, achievees the effect that pull the grass up by its roots, if 2-3 is used continuously in field, field broadleaf weeds can be greatly reduced
Radix.
The reasonable compounding and/or mixture of herbicide are to improve preventive effect, delay the speed of shift of weed community, reduce agriculture
Medicine single use bring resistance risk mitigates the pollution to environment, reduces the one of use cost and reduction herbicide residue
Kind effective ways.The present inventor to chlorine fluorine pyridine ester and ethoxysulfuron compound and/or mixture has made intensive studies, a large amount of
