Abstract
The invention provides a herbicide composite. The herbicide composite comprises a component A and a component B serving as active ingredients, wherein the component A is 2-[2-chloro-4-(methylsulfonylpyridine)-3-[[(tetrahydro-2-furyl)methoxy]methyl]benzoyl]-1,3-cyclohexanedione and the component B is an amide herbicide. The invention also provides a preparation prepared according to the herbicide composite of the invention and the application thereof. In the herbicide composite, by compounding and using the 2-[2-chloro-4-(methylsulfonylpyridine)-3-[[(tetrahydro-2-furyl)methoxy]methyl]benzoyl]-1,3-cyclohexanedione and the amide herbicide with different structure types and action mechanisms, the prevention and control effects of the two components on weeds in a paddy field are improved; and simultaneously the herbicide controlling spectrum of the two components used as a single component is enlarged.
Description
Technical field
The present invention relates to a kind of herbicidal composition and preparation thereof and application.
Background technology
Tefuryltrione is the three ketones weed killer herbicide, it is a kind of wide spectrum herbicides for use in paddy of killing weeds by suppressing the synthetic enzyme of plant pigment, be mainly used in preventing and kill off annual and perennial weed, comprise tool awns cyperus iria genus and the yellow line carbamide herbicides is had chemical sproof weeds all have highly effective resistant function.
The mechanism of action of alachlor, Acetochlor all is the synthetic growth that suppresses cell by impede protein matter, be that it enters Profilin enzymic activity in the plant corpus, protein can't be synthesized and death, mainly prevent and kill off annual gramineae, some broad-leaved and sedge weed;
The third careless amine is chloroamides class weed killer herbicide, mainly passes through the synthetic growth that suppresses cell of impede protein matter, and photosynthesis and respiration are had remote-effects.The third careless amine is the paddy field herbicides special, is mainly used in preventing and kill off the annual gramineous weeds such as barnyard grass, lady's-grass, moleplant seed, doublely controls part broad leaved weed and nutgrass flatsedge, such as Procumbent Falsepimpernel, Monochoria vaginalis, difformed galingale herb, cyperus iria, needle spikesedge herb etc.
Butachlor is the chloro-acetyl amine weed killer herbicide, the main synthetic growth that suppresses cell by impede protein matter, it is effectively anti-divided by the grassy weed of seed germination, annual nutgrass flatsedge and some annual broadleaf weeds, such as barnyard grass, moleplant seed, difformed galingale herb, cyperus iria, needle spikesedge herb etc. to be mainly used in paddy field and nonirrigated farmland.
Diflufenican is to belong to the carotenoids biosynthesis inhibitor, and carotenoid content descends in the processed plant, and then causes chlorophyll destroyed, membranolysis, and weeds show as the young shoot decolouring or bleach.When weed germination, all can absorb medicament by young shoot or root system and cause at last death.Dead speed is relevant with light intensity, and light intensity is then fast, and is then slow a little less than the light.
Flufenacet belongs to cell division and growth inhibitor, is mainly used in preventing and kill off numerous annual gramineous weeds such as Annual Ryegrass etc. and some broad leaved weed.
Isopropyl methoxalamine is the chloroacetanilide herbicides by the exploitation of Syngenta company, mainly is the synthetic growth that suppresses cell by impede protein matter.
Summary of the invention
The object of the present invention is to provide a kind of broad weed-killing spectrum, few, the significant herbicidal composition of herbicidal effect of dosage, described herbicidal composition preparation and application thereof also are provided.
