Abstract

The invention relates to pesticide composition containing bicyclopyrone, bromoxynil octanoate and a pyridine carboxylic acid herbicide. The pesticide composition is prepared from effective components and the balance of pesticide auxiliaries, wherein the effective components include bicyclopyrone, bromoxynil octanoate and the pyridine carboxylic acid herbicide; the pyridine carboxylic acid herbicide is selected from one of aminopyralid or fluroxypyr-mepthyl; bicyclopyrone accounts for 1%-30% of the composition by weight, bromoxynil octanoate accounts for 1%-30% of the composition by weight, and the pyridine carboxylic acid herbicide accounts for 1%-30% of the composition by weight. The pesticide composition contains the reasonable components, has the synergistic interaction response to weeds in the corn field, enlarges the weed control spectrum of a single dosage, and reduces the weed resistance risk.

Description

Fluorine benzofenap and bromoxynil octanoate and the composition pesticide of picolinic acid class herbicide
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of with fluorine benzofenap and bromoxynil octanoate with And picolinic acid class herbicide is the composition pesticide of effective ingredient, it is adaptable to corn field is prevented and kill off annual Weeds, especially with barnyard grass (Echinochloa crusgalli), Herba Portulacae (Portulaca Oleracea), Herba Euphorbiae Helioscopiae (Euphorbia helioscopia) is the corn field of advantage weeds.
Background technology
Fluorine benzofenap (Bicyclopyrone), for three ketones type herbicides, by root system of plant and Blade absorbs, and conducts in vivo, suppresses hydroxyphenyl pyravate dual oxide enzyme, causes the long-pending of tyrosine Tired, the biosynthesis of plastoquinone and tocopherol stops, and then causes chlorophyllous content to decline, and makes to plant It is dead that thing separate living tissue chlorosis produces albefaction, can prevent and kill off annual grassy weeds, can with soil list processing before Seedling and After Seedling, stem and leaf processes, and in soil, residual period is shorter, it is adaptable to field corn, sweet corn, ensiling jade Annual grassy weeds is prevented and kill off to succession crop safety in rice, seed production corn, yellow pop corn field.
Bromoxynil octanoate (Bromoxynil octanoate), for cyanophenyl class contact killing type herbicide, quilt Grass cutting blade is only capable of carrying out limited conduction, main inhibited photosynthesis after absorbing, and promotes blade chlorisis With produce withered speckle, be mainly used in prevent and treat Semen Tritici aestivi, corn field annual broadleaf weed, as storage, Herba Solani Nigri, Herba Xanthii, Herba seu Flos Convolvuli arvensis, Herba Commelinae, Herba Amaranthi tricoloris, knotweed, Herba chenopodii etc., in soil, the half-life is 15 days, to rear stubble Crop safety.
Chlorine Fampridine acid (aminopyralid), for picolinic acid class new herbicides, is mainly used in preventing Except annual and perennial broad leaved weed, it is widely used in mountain region, grassland, planting site and bare place weeds Prevent and kill off.
The different monooctyl ester of fluroxypyr (Fluroxypyr-meptyl) is that pyridine fluoroacetic acid class herbicide is Hormone like herbicide, can be conducted by the blade of plant and root absorption, makes plant deformity, distortion death, Mainly prevent and kill off annual broadleaf weed, invalid to grassy weed.The different monooctyl ester of fluroxypyr is suitable for Broad leaved weed such as Herba Galii Teneri, Herba stellariae mediae, Herba seu Flos Convolvuli arvensis, Dens Equi is prevented and kill off in gramineous crop field and fruit-bearing forest tea The broad leaved weeds such as Herba Amaranthi tricoloris, water peanut, Herba Acalyphae.
The acid of fluorine benzofenap, bromoxynil octanoate, chlorine Fampridine or the compounding nothing of the different monooctyl ester of fluroxypyr Relevant report.
Summary of the invention
It is an object of the invention to solve in prior art, weeds are developed immunity to drugs problem and actual preventing and treating Effect is poor, it is provided that one is efficiently, low toxicity, quick-acting are good and the lasting period is long, beneficially corn field one The composition pesticide of year raw weeds comprehensive control.
