Abstract
The invention discloses a weeding composition for rice paddy field. The weeding composition comprises active components including penoxsulam and propanil, wherein a mass part ratio of penoxsulam to propanil in the weeding composition is (1 : 20) to (1 : 400). The invention furthermore discloses a preparation method for dose forms. The weeding composition is used for preventing and controlling weeds in the rice paddy field, and has a remarkable synergistic effect; the weeding spectrum is expanded; single dose is reduced; and weed resistance is delayed.
Description
Technical field
The present invention relates to compound combination application technique, belongs to pesticide field, it is that two kinds of work are opposed by penoxsuam and barnyard grass
Property into subassembly, for preventing and treating farmland weed preventing and treating.
Background technology
Chemical method weeding is agriculturally to control one of Main Means of weeds.In recent years, due to some herbicide kinds
Large area is used alone, and already leads to many weeds and develops immunity to drugs.Meanwhile, grass when weeds occur is mutually complicated, not only 1 year
The mixed life of raw and perennial weeds, draft, liana and shrub have concurrently, and weeds emerge uneven, seed, and low age, advanced age are miscellaneous
Grass staggeredly occurs, so when herbicide kind is used alone, can show defect in a certain respect and limitation.
Penoxsuam (penoxsulam) is after seedling herbicide, and it is triazolopyrimidine sulfonamide herbicide, is passed through
Suppress acetolactate synthestase (ALS) and work.
Propanil (propanil) is high selectivity contact killing type herbicide, is hydrolyzed into by aryl carboxy group amidase in Oryza sativa L. body
3,4-DCA and propanoic acid and detoxify, barnyard grass is destroyed at first due to lacking this kind of removing toxic substances function, cell membrane, causes moisture
Metabolic disorder, quickly dehydration is withered.
The present inventor has made intensive studies to penoxsuam and propanil mixture, in substantial amounts of formula indoor screening test
On the basis of field medicine effect test, it is found that penoxsuam and propanil carry out mixture, it is right in the range of certain mixed ratio
Paddy field weed shows obvious potentiation, after further study, completes the present invention.
The content of the invention
It is an object of the invention to solve in prior art develop immunity to drugs to farmland weed problem and using effect, there is provided
A kind of efficient, preventing and treating spectrum is wide, is conducive to the Herbicidal combinations of farmland weed comprehensive control.
It is a further object of the present invention to provide the Herbicidal combinations are used to prevent and kill off farmland weed, it is particularly useful for preventing and kill off Oryza sativa L.
Field weed.
Technical solution of the present invention：A kind of Herbicidal composition for rice field, the active component of Herbicidal combinations is by penoxsuam
With propanil composition, the mass fraction ratio of penoxsuam and propanil in Herbicidal combinations is 1:20-1:400, penoxsulam
The preferred mass number ratio of amine and propanil in Herbicidal combinations is 1:20.
Penoxsuam mass percent in the composition is 0.01%～20%, propanil quality hundred in the composition
Divide than being 5%～80%, remaining is auxiliary agent.
Herbicidal combinations of the present invention contain pesticidal preparations auxiliary element, make so as to herbicidal composition and are adapted to agriculturally make
Dosage form, including suspending agent, dispersible oil-suspending agent, water dispersible granules, wettable powder.
Herbicidal combinations of the present invention are applied to prevent and treat paddy field weed, especially barnyard grass.
Compared with prior art, the beneficial effects of the present invention is：There is obvious potentiation, improve prevention effect；
Expand preventing and treating spectrum；Pesticide use amount is reduced, so as to reducing cost and reducing the pollution to environment；Delay Weed Resistance
Produce.
