Description

A kind of containing rimsulfuron and metribuzin and the Herbicidal combinations of oxalic acid
Technical field
The present invention relates to compound pesticide combination and application technology thereof, be by the phonetic sulphur of effective ingredient sulfone Grand, metribuzin and oxalic acid are combined, and are applied to prevent and kill off potato fields weeds.
Background technology
Rimsulfuron, sulfonylurea amino acid compound inhibitor, root, stem, leaf absorb, pass Be directed at separate living tissue, by suppress necessary valine and isoleucine biosynthesis so that Cell differentiation and plant growing stop.
Metribuzin, triazines inhibitor of photosynthesis, by weeds Root Absorption with transpiration current upwards Portion conducts, it is possible to is absorbed by blade and conducts in vivo.Mainly by suppressing the photosynthetic of sensitive plant Effect plays removing activity, and after dispenser, the sprouting of each susceptible weeds is emerged unaffected, posterior lobe of emerging Sheet chlorisis, last nutrition is exhausted and dead.
Oxalic acid, has another name called propaquizafop, phenoxy carboxylic acid fatty acid synthetic inhibitor, passes through weeds Stem, leaf absorb, Bidirectional Conduction up and down in plant, are accumulated in top and divide between two parties Raw tissue, suppression cell fatty acid synthesis, make weeds downright bad.
Chemical method weeding is one of Main Means of potato fields control weeds, have efficiently, Time and labour saving advantage.The grass that potato fields weeds occur is mutually complicated, and grassy weed, broad-leaved are miscellaneous Grass polymorphic type weeds are mixed raw, use single kind compound herbicide all can show in a certain respect Defect and limitation, it is impossible to be fully solved potato fields weed problem.Meanwhile, herbicide product Plant and be used alone, be easily caused weeds and develop immunity to drugs.
Combination and the application thereof of rimsulfuron, metribuzin and oxalic acid have been carried out deeply by the present inventor Enter research, on the basis that substantial amounts of Toxicity Determination, Recipe and land for growing field crops drug effect etc. are tested On, find that metribuzin and oxalic acid are combined in certain proportion, there is substantially increasing Effect effect, improves using effect, and expanding prevention is composed, it is adaptable to potato fields control of weeds. After further study, the present invention is completed.
Summary of the invention
It is an object of the invention to improve Pesticide use effect, expanding prevention spectrum, it is provided that a kind of association With potentiation containing rimsulfuron and metribuzin and the Herbicidal combinations of oxalic acid.
For achieving the above object, technical solution of the present invention: a kind of containing rimsulfuron and metribuzin And the Herbicidal combinations of oxalic acid, its effective ingredient is rimsulfuron and metribuzin and grass Acid, rimsulfuron percentage by weight in the composition is 0.5%～20%, and metribuzin is in combination Percentage by weight in thing is 2%～40%, and oxalic acid percentage by weight in the composition is 2%～40%, remaining is insecticides adjuvant.
The water dispersible granules Recipe technology of Herbicidal combinations of the present invention: rimsulfuron 0.5%～ 20%, metribuzin 2%～40%, oxalic acid 2%～40%, auxiliary agent complements to 100%.Will be effectively Composition, auxiliary agent are uniformly mixed, and pulverize with micro jet, through mediating, then add Fluidized bed granulating and drying machine carries out pelletize, dry, screening, can be prepared by required Water dispersible granules.
The wettable powder Recipe technology of Herbicidal combinations of the present invention: rimsulfuron 0.5%～ 20%, metribuzin 2%～40%, oxalic acid 2%～40%, auxiliary agent complements to 100%.Will be effectively Composition, auxiliary agent are uniformly mixed, and again through comminution by gas stream after mechanical activation comminution, can be prepared by institute The wettable powder needed.
The suspending agent formula Technology of Herbicidal combinations of the present invention: rimsulfuron 0.5%～20%, Metribuzin 2%～40%, oxalic acid 2%～40%, auxiliary agent complements to 100%.By compound and helping Agent mixes, and after sand milling in high speed shear dispersion, sand mill, forms high score in water-medium Scattered, stable suspension system, can be prepared by required suspending agent.
The oil-suspending agent Recipe technology that dispersibles of Herbicidal combinations of the present invention: rimsulfuron 1%～40%, oxalic acid 2%～50%, auxiliary agent complements to 100%.Effective ingredient, auxiliary agent are stirred Mix mix homogeneously, after sand milling in high speed shear dispersion, sand mill, formed in oil system medium High dispersive, stable suspension system, can be prepared by required dispersibling oil-suspending agent.
In the Herbicidal combinations of the present invention use auxiliary agent, including solvent, emulsifying agent, wetting agent, Stabilizer, dispersant, thickening agent, defoamer, antifreezing agent, disintegrating agent, binding agent, filling One or more mixing in agent, filler, medium etc., are known substance, are pesticidal preparations In conventional various auxiliary agents, can be varied from according to different situations, be not particularly limited.
Herbicidal combinations of the present invention is used for preventing and kill off potato fields weeds, use frequency and usage amount with Crops, weeds, weather condition change and have small variations, can be reached by suitable adjustment To effective application target.
The Herbicidal combinations that the present invention provides has the advantages that:
1, synergistic function, improves using effect；
2, expand weed control spectrum, prevent and treat plurality of classes weeds simultaneously, such as grassy weed, wealthy Leaf weeds, sedge weed；
3, the effective ingredient mechanism of action that compositions comprises is different, overcomes single use right Weeds easily produce resistance, extend compound service life；
4, reduce single compound formulation, circulation cost, reduce material and use, reduce Energy resource consumption.
