Abstract
The invention relates to an amidosulfuron-containing weeding composition as well as a preparation method and application thereof. The amidosulfuron-containing weeding composition comprises a compound (A) of amidosulfuron and a compound (B) selected from sulcotrione and nitro sulcotrione, wherein the weight ratio of the compound (A) to a compound (B1) or a compound (B2) is 1:1-50. After being mixed according to a proper proportion, the weeding composition can be processed into a normal pesticide formulation, such as wettable powder, dispersible oil suspending agent, water dispersible granule, and the like through the processing technology of a modern pesticide preparation, and is used for controlling and eliminating annual broadleaf weeds and some gramineae weeds, such as abutilon, burweed, amaranthus spinosus, chenopodium weeds, kochia scoparia, polygonum weeds, mustard leaves, cockspur grass, crabgrass, and the like in corn fields. The controlling effect of the weeding composition is remarkably higher than that of the single compound (A) or the single compound (B), and the application dosage of each active substance is greatly reduced.
Description
Technical field
The present invention relates to have the Herbicidal combinations that improves performance, relate to contain amidosulfuron and a kind of Herbicidal combinations that is selected from sulphur humulone or mesotrione and uses thereof specifically.
Background technology
The adopted name of compound (A) is an amidosulfuron, and chemical name is 1-(4,6-dimethoxy-2-pyrimidine radicals)-3-(N-methyl Methanesulfomide sulfonyl)-urea.
The English name of amidosulfuron: amidosulfuron.Other name is called: Allstate, Hoestar, hoe0750032.The CA accession number is: 120923-37-7.
Amidosulfuron is a kind of efficient sulfonylureas highy potent herbicide, belongs to sulfonylurea herbicide, can prevent and treat wheat, corn field broad leaved weed.Weeds absorb by cauline leaf and suppress cell division, and plant stops growing and death.
The amidosulfuron formulation of using on market at present mainly contains 50% amidosulfuron water dispersible granules.
The sulphur humulone general by name of compound (B1), chemical name are 2-(2-chloro-4-methylsulfonyl benzoyl) cyclohexane-1, the 3-diketone.
The English general sulcotrione by name of sulphur humulone, other name is called ICI A0051; SC0051.CA accession number: 99105-77-8.By J.M.Beraud report by ICI company (now be Zeneca Agrochemicals) found, obtained patent EP137963 (1985) in 1991 by the activity of weeding of ICI A0051 for the sulphur humulone.
The sulphur humulone is the blade face weed killer herbicide, also can absorb by the root of weeds, and residual soil activation is better than only having the post-emergence herbicide of blade face activity.This unique herbicidal effect is the key factor of preventing and kill off some weeds such as Amaranthus.The very fast decolouring in blade face behind the weeds absorption sulphur humulone, slowly dead.The sulphur humulone is mainly used in the broad leaved weed and the part grassy weeds such as lamb's-quarters, eggplant, black nightshade, knotweed, pale persicaria, lady's-grass, bloodroot, Ceylon barnyard grass and wild lamb's-quarters of preventing and kill off in corn, the sugarcane field.
The nitro sulphur humulone general by name of compound (B2), chemical name are 2-(2-nitro-4-methylsulfonyl benzoyl) cyclohexane-1, the 3-diketone.
The English name of nitro sulphur humulone is mesotrione, and the CA accession number is 104206-82-8.
The nitro sulphur humulone mechanism of action is for suppressing the activity to oxypyroracemic acid dioxygenase (HPPD).HPPD can be converted into plastoquinone with amino acid tyrosine, and it is the co-factor of octahydro lycopene desaturase, is the biosynthetic key enzyme of carotenoid.Use 3-5 days implants meristematic tissue of mesotrione the yellow symptom to occur, cause withered spot thereupon, spread all over whole strain plant behind the fortnight.Mesotrione tool faintly acid in the inoic acid soil, mainly exists to be difficult for absorbed anionic form.This product can be degraded fast widely, and final metabolite is carbonic acid gas, and the half life period mean value in the soil is 9 days, has degraded fast in soil, and characteristics such as consumption is low.
Be broadleaf herbicide behind the preceding bud of corn field bud, interior absorption arranged, broad weed-killing spectrum.Can effectively prevent and kill off annual broadleaf weed and some grassy weeds such as piemarker in the corn field, Siberian cocklebur, thorn amaranth, Chenopodium weeds, summer cypress, Polygonum weeds, leaf mustard, barnyard grass grass, lady's-grass.
The common ground of amidosulfuron and sulphur humulone, nitro sulphur humulone is the weeds that all can prevent and kill off in the corn field, and amidosulfuron mainly can be prevented and kill off the broad leaved weed in the corn field.Sulphur humulone, nitro sulphur humulone not only can have been prevented and kill off the grassy weed in the corn field but also can prevent and kill off part broad leaved weed in the corn field.Do not appear in the newspapers with the suitable ratio weeds that are used for preventing and kill off in the corn field that are mixed for amidosulfuron and sulphur humulone or nitro sulphur humulone.The use of composition not only can improve drug effect, reduces dosage, saves Financial cost, reduces medicament residual in environment.
Summary of the invention
The Herbicidal combinations that the purpose of this invention is to provide amidosulfuron and sulphur humulone, nitro sulphur humulone, after suitable ratio mixing, by modern pesticidal preparations process technology, but be processed into conventional pesticide formulations such as wetting powder dispersed oil suspending agent, water dispersible granules, be used for preventing and kill off annual broadleaf weed and some grassy weeds such as piemarker, Siberian cocklebur, thorn amaranth, Chenopodium weeds, summer cypress, Polygonum weeds, leaf mustard, barnyard grass grass, lady's-grass of corn field.
