Abstract
The invention discloses a kind of herbicide composition for paddy fields, belong to the cooperative compositions technical field of herbicide, including by the active component of contact killing type herbicide and osmosis type combinations of herbicides；The contact killing type herbicide is propanil, and the osmosis type herbicide is 2,4 D or derivatives thereof, and the percentage by weight of the contact killing type herbicide and the osmosis type herbicide is 1:1~40:1, described 2,4 D derivative are one kind in 2,4 D butyl esters, 2, the 4 different monooctyl esters of D, 2,4 D amine salt；Said composition can improve the preventive effect to weeds, reduce dosage, reduce use cost, solve the problems, such as the Weed Resistance occurred at present.
Description
Technical field
The present invention relates to the cooperative compositions technical field of herbicide, in particular to a kind of herbicide composition for paddy fields.
Background technology
Propanil is a kind of contact killing type herbicide of amide-type high selectivity, is mainly used in preventing and kill off rice terrace grass family and Shuangzi
Leaf weeds, such as Monochoria vaginalis, Chinese celery, lady's-grass, green bristlegrass, are the specific drugs for preventing and kill off barnyard grass.Propanil is hardly defeated in plant
Lead, simply worked in medicament contact site.Its mechanism of action is many, not only breaks up the photosynthesis of plant, and
And also suppressing respiration and oxidative phosphorylation, RNA is synthesized with protein, so that the physiology of sensitive plant
Function is affected, and accelerates dehydration, blade gradually dried-up, last dead.Divide rapidly because propanil is hydrolyzed enzyme in paddy rice body
Solution is into innocuous substance, so to rice safety；In the prior art, propanil and other herbicides are made up of to removing of cooperateing with inventor
Careless composition, to improve herbicidal effect, extends the appearance of Weed Resistance, such as application publication number is the A of CN 102265852 China
Patent of invention is disclosed after a kind of Herbicidal combinations containing bentazone and propanil and its application, bentazone and propanil combination, its group
The herbicidal effect of compound, weeding broad spectrum activity and extend the effect of Weed Resistance and lifted.
And 2,4-D is the Plant Hormone synthesized first in nineteen forty-one by American R. Bo Keni.Nineteen forty-four U.S.'s agriculture
Industry radical reports 2,4-D herbicidal effect, afterwards because its consumption is few, cost is low, drug effect is high receives major agrochemical enterprises
Pursue, become one of herbicide kind main in the world.2,4-D can be prevented and kill off in the crop fields such as wheat, rice, corn, sugarcane
The broad leaved weeds such as lamb's-quarters, amaranth and budding period grassy weed.2,4-D can enter in plant from root, stem, leaf, and degraded is slow, therefore can
Finite concentration is accumulated, so as to disturb plant hormone in vivo to balance, destruction nucleic acid and protein metabolism promote or suppressed some organs
Growth, distorts weeds cauline leaf, stem foot is thicker, swells and splits.The further discovery of related researcher later, 2,4-D
Derivative 2, the different monooctyl ester of 4-D butyl esters, 2,4-D, 2,4-D amine salt equally have higher activity of weeding, and they can prevent and kill off wealthy
Leaf weeds and grassy weed.2,4-D derivative has stronger uptake and translocation, and decoction sprays application to weeds cauline leaf surface
Afterwards, through cuticula and cytoplasma membrane, finally it is transmitted to plant each several part.The aggrieved rear cauline leaf distortion of weeds, deformity are final dead,
24 hours broad leaved weeds are that deformity curling symptom occurs as medication is latter, death in 7 ~ 15 days.
As herbicide products are in the use of the large area for many years of rice terrace, occur at present in terms of paddy field weed is prevented and kill off
Many problems：（1）Weed Resistance is protruded, and in recent years because the usage amount of herbicide increases year by year, causes herbicide resistance
Develop rapidly, or even have there is " superweed " resistant to a variety of herbicides in some areas；（2）The danger of perennial weeds
The problem of evil becomes main；（3）The herbicide controlling spectrum of herbicide kind needs to be expanded, and extends the lasting period that soil prevents and kill off medicament；
（4）The demand of the herbicide kind strong, easy to use to wide spectrum, selectivity is more urgent.
Because the compounding of different activities composition has cooperative effect, usage amount, therefore applicant couple can be significantly reduced
Propanil and 2,4-D and its derivative carry out the compounding of different proportion, to solve to be faced in terms of preventing and controlling weed in rice field at present
The problem of.
The content of the invention
Present invention aim to provide a kind of herbicide composition for paddy fields, it can improve the preventive effect to weeds,
Dosage is reduced, use cost is reduced, the Weed Resistance occurred at present is solved the problems, such as.
To achieve the above object, a kind of herbicide composition for paddy fields designed by the present invention, including by contact killing type weeding
