Abstract
The invention provides a synergism weeding composition for a paddy field. The synergism weeding composition comprises three components of mesotrione, mefenacet and halosulfuron-methyl with a weight part ratio of (2.5-6):(20-70):(1-2.5). According to the synergism weeding composition, the three components of the mesotrione, the mefenacet and the halosulfuron-methyl are compounded, thus the problem of resistance weeds is solved, the herbicide controlling spectrum to the weeds is enlarged, the weeds in the paddy field can be basically solved through once application of the synergism weeding composition, the work, the time and the labor are saved, and a certain action is achieved for increasing the yield and income of rice. Meanwhile, according to the synergism weeding composition, the use dosage of a pesticide is reduced, the adverse effect of the pesticide on an ecological environment is reduced, and the generation of the pesticide resistance is delayed. In addition, the synergism weeding composition can be processed into multiple time and labor-saving preparations, is directly spread and applied without being sprayed, and has meaning in today of increasing the labor cost more and more.
Description
Technical field
The invention belongs to technical field of pesticide, relate to particularly the paddy field Synergistic herbicide compositions for intractable weeds such as resistant weed such as angustifolia arrowhead herb, dayflower, nutgrass flatsedge, barnyard grass and moleplant seeds.
Background technology
The use of weed killer herbicide has reduced peasant's labour intensity greatly, but along with the long-term use of conventional weed killer herbicide, also make weeds produce great resistance, simply strengthen dosage and can not deal with problems, and strengthening dosage has increased cost on the one hand, has also polluted on the other hand environment.At present, there is a large amount of resistance angustifolia arrowhead herb, dayflower in the paddy field in northeast, and the weeds such as a large amount of nutgrass flatsedges, barnyard grass, moleplant seed have appearred in south rice field, and on market, existing weed killer herbicide preventive effect is very micro-, and peasant brother feels simply helpless.
Mesotrione, has another name called mesotrione, chemical name: 2-(4-mesyl 2-nitro-benzoyl) thiacyclohexane-1,3-diketone, structural formula is:
This weed killer herbicide is corn field Common Herbicides, with its broad weed-killing spectrum, active high, miscibilty strong, to succession crop safety, use flexibly, Environmental compatibility is strong etc., and feature has compared with great development and is worth and promotes the use of preferably prospect in China.By test, the present invention further expands it in the application at paddy field, and finds that the Alismataceae weeds such as its antagonism angustifolia arrowhead herb, dayflower have special efficacy.
Mefenacet, has another name called the careless amine of ring, chemical name: 2 one benzothiazoles-2-base oxygen-N-nitre antifebrin, and structural formula is:
This weed killer herbicide is a kind of selectivity inner-adsorption conduction-type herbicide, soil is very strong to this product absorption affinity, after dispenser, dose major part is adsorbed on upper soll layer, can effectively prevent and kill off grassy weed, barnyard grass is had to special efficacy in rudiment to the 2 leaf phase, to moleplant seed, needle spikesedge herb, wartwort, Monochoria vaginalis, mexicana, special-shaped nutgrass flatsedge, flat nutgrass flatsedge, cyperus iria and for many years aquatic nutgrass flatsedge also have certain preventive effect.
Halosulfuronmethyl, chemical name: 3-(4,6-dimethoxypyridin-2-yl)-1-(1-nitre-3-chloro-4-methoxy formoxyl pyrazoles-5-yl) sulfonylureas, structural formula is:
This weed killer herbicide belongs to sulfonylurea herbicide, for agent for removing grass in paddy field, can prevent and kill off broad leaved weed and Sha Ke weeds, as angustifolia arrowhead herb, rhizoma alismatis, nutgrass flatsedge etc.Prove by experiment: the sedge weed rhizome of nutgrass flatsedge and angustifolia arrowhead herb are had to special efficacy.
Although mesotrione, mefenacet and halosulfuronmethyl be all can single use weed killer herbicide, use all has certain defect and limitation separately.In addition, use although prior art has report can select two or three in these three kinds of weed killer herbicides to mix, do not record about concrete mixed ratio and select the system experimentation research to weeding resultant effect.On the whole, on the one hand, existing weed killer herbicide single or mixture all still exists that herbicide spectrum is narrow, dosage large, to defect and limitation such as the anti-heterodynes of malignant weed; On the other hand, prior art does not instruct the mixture use of above three kinds of weed killer herbicides can address the aforementioned drawbacks completely and the enlightenment of circumscribed technology.
Summary of the invention
An object of the present invention is disposable resistant weeds all in paddy field such as angustifolia arrowhead herb, dayflower, nutgrass flatsedge, barnyard grass, the moleplant seed etc. prevented and kill off, greatly expand the restriction of mesotrione, mefenacet or halosulfuronmethyl herbicide spectrum separately, solve the resistance problem of weeds.
Another object of the present invention is significantly to reduce the amount of the required active component of control of weeds, thereby reduces environmental pollution and reduce costs.
Another object of the present invention is to improve herbicide speed, particularly the herbicide speed to grass family, broad-leaved section weeds.
In order to realize above-mentioned one or more objects, the present invention adopts following technical scheme:
A kind of paddy field Synergistic herbicide compositions, it is characterized in that: described Herbicidal combinations comprises mesotrione, mefenacet and three kinds of components of halosulfuronmethyl, and mesotrione, mefenacet and the halosulfuronmethyl ratio of weight and number in described Herbicidal combinations is 2.5～6:20～70:1～2.5.
In a preferred embodiment, mesotrione, mefenacet and the halosulfuronmethyl ratio of weight and number in described Herbicidal combinations is 3:25:1.
In a preferred embodiment, described Herbicidal combinations also comprises auxiliary agent.
