Description

Composition pesticide containing fluorine benzofenap and halosulfuronmethyl and bromoxynil octanoate
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Synergistic response composition pesticide being effective ingredient with fluorine benzofenap, halosulfuronmethyl, bromoxynil octanoate, it is adaptable to prevent and kill off corn field annual grassy weeds.
Background technology
Fluorine benzofenap (Bicyclopyrone), for three ketones type herbicides, absorbed by root system of plant and blade, and conduct in vivo, suppress hydroxyphenyl pyravate dual oxide enzyme, cause the accumulation of tyrosine, the biosynthesis of plastoquinone and tocopherol stops, and then cause that chlorophyllous content declines, plant separate living tissue chlorosis is made to produce albefaction dead, annual grassy weeds can be prevented and kill off, can before Seedling after soil list processing and Seedling stem and leaf process, in soil, residual period, is shorter, suitable in field corn, sweet corn, silagecorn, seed production corn, annual grassy weeds is prevented and kill off to succession crop safety in yellow pop corn field.
Halosulfuronmethyl (Halosulfuron-methrl), for sulfonylurea wide spectrum selectivity inner-adsorption conduction-type herbicide, absorbed mainly through root system, also can be absorbed by stem and leaf, shifting rapidly in weeds plant body, it is suppressed that growth, weeds are dead gradually, annual broadleaf weed and sedge weed can be prevented and kill off, it is adaptable to the crop such as Semen Maydis, Oryza sativa L..
Bromoxynil octanoate (Bromoxyniloctanoate), for cyanophenyl class contact killing type herbicide, it is only capable of after being absorbed by grass cutting blade carrying out limited conduction, main inhibited photosynthesis, promote blade chlorisis and produce withered speckle, being mainly used in preventing and treating Semen Tritici aestivi, corn field annual broadleaf weed, such 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 succession crop safety.
