Abstract
The invention discloses a weed killer composition having a broad spectrum weed killing effect, and relates to the technical field of production of weed killer compositions having a broad spectrum weed killing effect. According to the present invention, the active ingredients comprise bensulfuron methyl and (E)-pyriminobac-methyl, and the weed killer composition comprises, by mass, 5-25% of bensulfuron methyl, 3-25% of the (E)-pyriminobac-methyl, 4.05-34% of an assistant agent, and 16-87.95% of a filler; the weed killer composition provides the outstanding effects compared with the single active ingredient weed killer, the bensulfuron methyl and the (E)-pyriminobac-methyl are compounded so as to provide characteristics of low toxicity, low residue, wide weed killing spectrum, rapidness and good persistence, the cost is low, and the weed killer composition is widely applied in killing of various weeds in rice fields and does not have adverse effects on crops.
Description
Technical field
The present invention relates to the production technical field of the herbicidal composition of broad spectrum weeding function.
Background technology
Paddy rice is the main food long-term cropping of China, and national rice growing area is stabilized in about 4.5 hundred million mu always for many years.Along with the continuous propagation and employment of paddy rice cultivation technique, direct seading rice development is particularly swift and violent.Because it has the huge advantage of dart transfer, liberating rural productivity, progressively become a kind of tool rice cropping mode with broad prospects for development in China main paddy rice producing region at present.Due to planting type and the feature in direct seading rice field, the crop smothering generation problem in direct seading rice field is very outstanding.
KIH 6127 is that a kind of inner sucting conduction type specialty that Japanese combinatorial chemistry is researched and developed recently removes barnyard grass agent, belong to pyrimidinylthiobenzoate herbicides, it can by the cauline leaf of weeds and root absorption, and conduct to complete stool rapidly, suppress acetolactate synthestase (ALS) and amino acid whose biosynthesis, thus suppress and hinder the cell division in weeds bodies, weeds are stopped growing, finally makes weeds albefaction and withered.
Bensulfuron-methyl is selectivity inner-adsorption conduction-type herbicide.Active ingredient can spread rapidly in water, transfers to each portion of weeds, the biosynthesis of hindered aminoacid, lysine, isoleucine, stop division and the growth of cell for weeds root and blade absorb.Susceptible weeds GF is obstructed, and tender tissue turns to be yellow too early and suppresses the growth of leaf portion, hinders root growth and downright bad.It is harmless inert chemi-cal thing that active ingredient enters rapid metabolization in paddy rice body, to rice safety.Using method is flexible, available pesticide-clay mixture, mispickel, spraying, sprinkles methods such as watering.In soil, mobility is little, and temperature, soil property are little on the impact of its herbicidal effect.
Summary of the invention
The object of the invention is for current wide spectrum, highy potent herbicide lacks and existing weed killer herbicide exists multiple weak point, provide a kind of with wetting powder or suspending agent for formulation, there is herbicidal composition that is efficient, broad spectrum weeding function simultaneously.
Active ingredient of the present invention is made up of bensulfuron-methyl and KIH 6127, wherein bensulfuron-methyl, KIH 6127, auxiliary agent and filler account for respectively composition gross mass 5 ~ 25%, KIH 6127 3 ~ 25%, 4.05 ~ 34% and 16 ~ 87.95%, the percentage by weight summation of composition is 100%.
The present invention's more single use active ingredient has outstanding effect, by bensulfuron-methyl and the composite use of KIH 6127, also have low toxicity, low-residual, herbicidal spectrum is wide, quick-acting and lasting effect is good feature, cost is low, preventing and kill off extensive use in all kinds of weeds of paddy field, crop is had no adverse effects.
Formulation of the present invention can be suspending agent or wetting powder.
The auxiliary agent of wetting powder is made up of with the wetting agent 1 ~ 5% accounting for composition gross mass the dispersant 1 ~ 20% accounting for composition gross mass.
The auxiliary agent of suspending agent is by accounting for the dispersion moisture agent 1 ~ 15% of composition gross mass, the antifreeze 0.3 ~ 3% accounting for composition gross mass, the thickener 0.4 ~ 5% accounting for composition gross mass and the defoamer 0.3 ~ 2% that accounts for composition gross mass forms.
