Description
Technical field
The present invention relates to a kind of soluble preparation containing glyphosate and flumioxazin belongs to the technology neck of the formulations of pesticide
Domain.
Background technique
Glyphosate is a kind of wide spectrum interior suction steriland herbicide, and conductibility is extremely strong, is absorbed by the green parts of weeds,
Conduction hinders the photosynthesis of plant, leads to careless death, it is miscellaneous can to effectively prevent one, biennial unifacial leaf grass family to complete stool
Grass, it is especially extremely strong to the underground organization destructive power of perennial deep root weeds, the depth that general agricultural machinery is unable to reach can be reached,
In agriculture, woods, herds, is widely used in terms of gardening.But the product weakness that there are quick-acting is poor, low temperature active is low, while resistance
Weeds type is more and more.
Flumioxazin is the herbicide absorbed by young shoot and blade, and making soil treatment, can effectively to prevent and kill off annual broad-leaved miscellaneous
Grass and part gramineae weed, it is degradable in the environment, to succession crop safety.Soybean, peanut have good drug resistance to it.
Corn, wheat, barley, rice have medium patience, are suitable for the crop fields such as soybean, peanut, orchard and prevent and kill off annual broad-leaved
Weeds and part gramineae weed.
After compounding prior art has disclosed glyphosate with flumioxazin, co-toxicity coefficient is higher, and it is quick-acting to solve glyphosate
The defect that property is poor, low temperature active is low.If CN108782597A discloses a kind of suspending agent containing glyphosate and flumioxazin,
Middle effective component glyphosate 1%-50%, flumioxazin 0.1%-30% and other auxiliary materials.The suspensions stability is good,
Synergy is significant, for preventing and treating Cotton Fields gramineae weed and broadleaf weeds.
However, in practical applications, finds the suspending agent there are drug effects under cryogenic conditions that poor, preparation is unstable etc. and ask
Topic.In view of this, the present invention is specifically proposed.
Summary of the invention
