The invention discloses a weeding composition containing metribuzin and propaquizafop and application thereof. The effective components are metribuzin and propaquizafop by the weight part ratio of 20:1-1:20. The weeding composition is used for preventing and controlling annual weeds of a potato field, has an obvious synergistic effect, improves the using effect, enlarges the prevention and control spectrum, reduces dosage, reduces adverse effects on ecological environment by pesticide, is beneficial for treating weed resistance and has huge economic and social benefits.
Description
Technical field
The present invention relates to compound pesticide combination and application technology thereof, be to be combined by effective ingredient metribuzin and oxalic acid, be applied to prevent and kill off potato fields weeds.
Background technology
Metribuzin, triazines inhibitor of photosynthesis, is conducted to top with transpiration current by weeds Root Absorption, it is possible to absorbed by blade and conduct in vivo.Mainly playing removing activity by the photosynthesis of suppression sensitive plant, after dispenser, each susceptible weeds is sprouted and is emerged unaffected, and rear blade chlorisis of emerging, last nutrition is exhausted and dead.
Oxalic acid, has another name called propaquizafop, phenoxy carboxylic acid fatty acid synthetic inhibitor, is absorbed by weeds stem, leaf, Bidirectional Conduction up and down in plant, is accumulated in top and intercalary meristem, suppression cell fatty acid synthesis, makes weeds downright bad.
Chemical method weeding is one of Main Means of potato fields control weeds, has efficient, time and labour saving advantage.The grass that potato fields weeds occur is mutually complicated, grassy weed, the mixed life of broad leaved weed polymorphic type weeds, uses single kind compound herbicide all can show defect in a certain respect and limitation, it is impossible to be fully solved potato fields weed problem.Meanwhile, herbicide kind is used alone, and is easily caused weeds and develops immunity to drugs.
Metribuzin and the combination of oxalic acid and application thereof are conducted in-depth research by the present inventor, on the basis of the tests such as substantial amounts of Toxicity Determination, Recipe and land for growing field crops drug effect, find that metribuzin and oxalic acid are combined in certain proportion, there is notable synergistic effect, improve using effect, 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 synergistic function containing metribuzin and the Herbicidal combinations of oxalic acid.
For achieving the above object, technical solution of the present invention: a kind of containing metribuzin with the Herbicidal combinations of oxalic acid, comprise effective ingredient metribuzin, oxalic acid, metribuzin is 20:1～1:20 with the part by weight of oxalic acid；Metribuzin percentage by weight in the composition is 2%～40%, and oxalic acid percentage by weight in the composition is 2%～40%, and remaining is auxiliary agent.
Herbicidal combinations of the present invention can be prepared as wettable powder, water dispersible granules, suspending agent by Recipe technology, be dispersibled the one of oil-suspending agent；.
The water dispersible granules Recipe technology of Herbicidal combinations of the present invention: metribuzin and oxalic acid 4%～80%, auxiliary agent complements to 100%.Effective ingredient, auxiliary agent are uniformly mixed, pulverize with micro jet, through mediating, be subsequently adding in fluidized-bed granulation dryer and carry out pelletize, dry, screening, can be prepared by required water dispersible granules.
The wettable powder Recipe technology of Herbicidal combinations of the present invention: metribuzin 2%～40%, oxalic acid 2%～40%, auxiliary agent complements to 100%.Effective ingredient, auxiliary agent are uniformly mixed, again through comminution by gas stream after mechanical activation comminution, can be prepared by required wettable powder.
The suspending agent formula Technology of Herbicidal combinations of the present invention: metribuzin 2%～40%, oxalic acid 2%～40%, auxiliary agent complements to 100%.Compound and auxiliary agent are mixed, after sand milling in high speed shear dispersion, sand mill, water-medium is formed high dispersive, 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: metribuzin 2%～40%, oxalic acid 2%～40%, auxiliary agent complements to 100%.Effective ingredient, auxiliary agent are uniformly mixed, through high speed shear dispersion, in sand mill after sand milling, oil system medium form high dispersive, stable suspension system, can be prepared by required dispersibling oil-suspending agent.
The auxiliary agent used in the Herbicidal combinations of the present invention, one or more mixing in including solvent, emulsifying agent, wetting agent, stabilizer, dispersant, thickening agent, defoamer, antifreezing agent, disintegrating agent, binding agent, filler, filler, medium etc., it is known substance, it is various auxiliary agents conventional in pesticidal preparations, 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, uses frequency and usage amount to have small variations with crops, weeds, weather condition change, can reach effective application target by suitable adjustment.
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, such as grassy weed, broad leaved weed, sedge weed simultaneously；
3, the effective ingredient mechanism of action that compositions comprises is different, overcomes single use generation easy to weeds resistance, extends compound service life；
4, reduce single compound formulation, circulation cost, reduce material and use, reduce energy resource consumption.
