Abstract
The weedicide composition contains at least weedicide A and a kind of weedicide B. The weedicide A is 4,6-bis(diisopropyl amino)-2-methlthio-1,3,5-triazinyl nicosulfuron, named also prometryne.
Description
The present invention relates to prometryn and have a kind of herbicides compounds B at least, compd B is: B

At present, corn field herbicide mainly is based on closed soil, mainly carries out closed soil treatment before the seedling with Acetochlor in the weed killer herbicide.Because the agent of Acetochlor list has been used for many years, in the certain areas weeds it is had fixed pesticide resistance, must increase consumption, but bring the problem of poor stability.And that the prometryn complex preparation is used at home is less, especially in corn field and soybean field.Prometryn and alachlor, Acetochlor, propisochlor, isopropyl methoxalamine, butachlor, ethoxy carboxylic grass ether, Pendimethalin are re-dubbed preparation, they can enlarge kill the grass spectrum, improve herbicidal effect, reduce residual activity, reduce poisoning, delay the drug-fast generation of weeds and the succession of community crop, the reduction dosage, reduce environmental pollution; Laborsaving simultaneously, economical, reduce farmer's burdens.
Composition of the present invention can be two combinations, also can be the composition that aforesaid compound forms more than three kinds.
The mechanism of action difference of the various compositions of composition of the present invention, mutually synergy between them, the pesticide resistance of weeds reduces, so the herbicidal effect of composition is obviously high slightly or the suitable herbicidal effect of single time spent of each component, and kills the grass spectrum and broadens.
Composition of the present invention is mainly used in corn field, soybean field, mainly prevents and kill off upland field weeds such as lady's-grass, green foxtail, wild oat, eleusine indica, salsola collina, Amaranthus retroflexus, acalypha copperleaf, kitchen garden, black nightshade, multitude, Siberian cocklebur, meadow pine, chickweed.
Prometryn and alachlor, Acetochlor, propisochlor, isopropyl methoxalamine, butachlor, ethoxy carboxylic grass ether, Pendimethalin weeding ratio are 1: 160 to 80: 1 based on the parts by weight of active component in the present composition, optimal proportion 1: 40 to 40: 1.
Composition of the present invention can also comprise emulsifier, solvent, auxiliary agent, filler, oils (vegetable oil, mineral oil) etc., and the parts by weight of its shared composition are 0.5%～95%.
The best preparation of composition of the present invention has: oil-suspending agent, aqueous suspension agent, suspension emulsion, aqua, also can be other formulations such as missible oil, pulvis, dust agent, granula, microemulsion, wetting powder and granule.
Composition of the present invention also will add surface reactive materials such as emulsifier, dispersant, wetting agent, to increase stability, wetability, the permeability of composition.
The product that the present invention describes can be the finished product preparation form, and promptly material mixes in the product.Yet the composition of composition also can provide with preparation separately, directly mixes in jar before use.
Composition of the present invention can use by common method, as spraying.
