Description

A kind of Herbicidal combinations

Technical field

The invention belongs to pesticide field, more particularly to a kind of Herbicidal combinations and a kind of undesirable plant growth of control Method.

Background technology

World food production is huge because of disease, worm, crop smothering loss every year, and the whole season of growth of crop nearly all can be by each The infringement of kind weeds, Weed infestation are also the key factor for restricting crop yield.Therefore, the preventing and treating of agricultural weed is always agriculture The problem of being concerned about the most in industry production and be important.

Protect crops from suppress crop growth weeds and the infringement of other vegetation be asking of persistently occurring in agricultural Topic.To solve the problem, the chemicals and chemicals of many control weed growths use in business.

Isoxaflutole (Isoxaflutole, CAS NO.141112-29-0), it is double to belong to p-hydroxybenzene pyruvic acid (HPP) ester Oxidase inhibitor HPPD inhibitor.Isoxaflutole mainly works via weeds young root Assimilation and conductivity, and susceptible weeds absorb After this medicine, by suppressing the synthesis of p-hydroxybenzene pyruvic acid (HPP) ester dual oxide enzyme, cause the accumulation of tyrosine, make plastoquinone The biosynthesis of tocopherol be obstructed, and then have influence on the biosynthesis of carotenoid.Isoxaflutole is to corn, sugarcane, sweet tea The safety such as dish, it is high to environment, the compatibility of ecology and security.Isoxaflutole can prevent and kill off annual broadleaf weed, such as right Tong fiber crops, Siberian cocklebur, lamb's-quarters, summer cypress, chickweed, black nightshade, Veronica, Amaranthus retroflexus, purslane etc.；Isoxaflutole is to barnyard grass, eleusine indica, horse Grassy weeds such as Tang, knucklegrass, moleplant seed, green bristlegrass and faber bristlegrass herb etc. also have preferable preventive effect.Isoxaflutole is before seedling With after seedling broad spectrum weeding agent, usually as processing soil treatment agent.

Butachlor (Butachlor), it is by the herbicide of the chloro-acetyl amine of Monsanto Company's exploitation.Butachlor is main Suppress the growth of cell by hindering the synthesis of protein, i.e., absorbed by weed bud and immature secondary root, suppress body Internal protein synthesizes, and makes the enlargement of weeds shoot, deformity, color depth green, ultimately results in death.Butachlor is mainly used in paddy field and nonirrigated farmland Effectively prevent divided by seed sprouts grassy weed, annual nutgrass flatsedge and some annual broadleaf weeds such as barnyard grass, moleplant seed, different Type nutgrass flatsedge, cyperus iria, needle spikesedge herb etc..Butachlor has preferable preventive effect to Monochoria vaginalis, Drilgrass, cusp flower and firefly leaves of pulse plants etc., but It is nearly unavailable to perennial weeds such as water Rhizoma Sparganii, flat stalk Fischer grass, angustifolia arrowhead herbs.

The use of chemical herbicide is one of important symbol of agricultural modernization, and in recent years, the sales volume of herbicide increases year by year Add, administration area also expands year by year.But as the large area of numerous herbicide kinds persistently uses, the problem of many is produced, Such as Weed Resistance problem starts to show especially, the resistance problem of especially elder weed is especially prominent；In addition, herbicide single dose effect side The problems such as formula is single, the lasting period is short is also than more prominent.Therefore, it is wide, selective by force and to the anti-medicine of weeds to presently, there are weeding scope The active demand of the property less release weedicide of pressure.

In some cases, have shown that herbicidal active component is more effective in combination compared with being administered alone, this claims For " synergy ".Synergy is two or more factor interactions so that effect ratio is based on applying respectively upon combination It is good with the effect desired by the response of each factor.The present invention based on the finding that：Each known isoxazole with herbicidal efficacy Humulone, butachlor show synergistic action effect when being administered in combination.
