Abstract
The invention discloses a kind of Herbicidal combinations containing clomazone and its application, the Herbicidal combinations are made up of clomazone, symetryne and S-metolachlor and other auxiliary agents and filler, and formulation is missible oil, dispersible oil-suspending agent or aqueous suspension agent.Three kinds of active component compoundings have obvious synergistic effect, reduce Pesticide use amount, reduce cost and the pollution to environment, the application of composition can delay the resistance to the action of a drug of paddy field weed, expand and prevent and kill off spectrum.
Description
Technical field
The present invention relates to Herbicidal combinations and its application of technical field of pesticide, more particularly to a kind of Han clomazones.
Background technology
Symetryne is interior suction selective herbicide, can be absorbed by root, leaf and conduct complete stool, to rice field malignant weed eye
Dish has special efficacy, has remarkable result to early stage barnyard grass, fescue, and the lasting period is long, to rice safety.
Clomazone also known as clomazone.It is a kind of selective pigment suppressive developed by FMC companies of the U.S. for 1984
Preemergence herbicide, can be absorbed by root, young shoot, each position of plant is transmitted to upwards with transpiration, in sensitive plant body
Interior suppression chlcrophyll biosynthesis, although energy rudiment is unearthed, but non-pigment, albefaction is dead in a short time.Clomazone is mainly prevented
Except broad leaved weed and grassy weed, it can be used for the weeding of soybean, cotton, cassava, corn, rape, sugarcane and Tobacco Farm etc..
S-metolachlor belongs to selective preemergence herbicide, is mainly absorbed by young shoot, young root after medicament, suppresses albumen
Matter synthetic lethal.It is usually used in corn and soybean, peanut, sugarcane, it can also be used to cotton, rape, potato and the ocean of non-sand loam soil
The crops such as green onion, capsicum, wild cabbage, preventing and treating annual gramineous weed and some broad leaved weeds, make native face processing before budding.
Herbicide single dose preventing and treating grass is used alone farmland weed and developed immunity to drugs to single, therefore by three kinds of herbicides
Science is assembled, and selects suitable formulation, so as to expand herbicide controlling spectrum, reduces times for spraying and dosage, is that current rice region is badly in need of solution
Certainly the problem of.
The content of the invention
A kind of Herbicidal combinations for Han clomazones that the present invention is provided, three kinds of active component compoundings have obvious synergy
Effect, reduces Pesticide use amount, reduces cost and the pollution to environment, and the application of composition can delay the anti-of rice weed
The property of medicine, expands and prevents and kill off spectrum.
Present invention simultaneously relates to application of the Herbicidal combinations in preventing and treating paddy field weed.
The present invention is achieved by the following technical solutions：
A kind of Herbicidal combinations of Han clomazones, it is characterised in that the active component You clomazones of the composition, west grass
Net and S-metolachlor is 2.75 according to mass ratio: 0.25-0.5：0.25-4 is constituted.
Preferably, Herbicidal combinations , clomazones, symetryne, the mass ratio of S-metolachlor are 2.75:0.25：
2。
Preferably, the formulation of above-mentioned Herbicidal combinations is missible oil, dispersible oil-suspending agent or aqueous suspension agent.
When formulation is missible oil, it is made up of following mass percent：Active component 15-40%, emulsifying agent 4-15%, cosolvent 2-
8%, balance of solvent.
When formulation is dispersible oil-suspending agent, it is made up of following mass percent：Active component 15-40%, dispersant 3-
8%, emulsifying agent 5-15%, wetting agent 2-5%, thickener 2-5%, antifreezing agent 1-3%, decentralized medium surplus.
When formulation is aqueous suspension agent, it is made up of following mass percent：Active component 15-40%, dispersion moisture agent 3%-6%,
Thickener 1.5-2%, preservative 0.2%, antifreezing agent 1-2%, defoamer 0.2%, synergist 3-5%, surplus is water.
The application of Herbicidal combinations described above in preventing and treating paddy field weed.
Each active component is due to composition, structure, the difference of physicochemical property after different herbicidal activity component mixing so that each
Synergy between active component is usually expressed as synergistic effect, summation action or antagonism.So-called synergistic effect is exactly
Effect is cooperated between different material, its effect produced is more than the sum total of each composition effect；And summation action is exactly it
The effect of generation is equal to the sum total of each composition effect；When antagonism refers to that two kinds of materials act on living organism, generate
A kind of material disturbs the effect of another material, or the effect of interfering with an opponent each other, makes what general effect declined
Phenomenon.
The present invention dexterously make use of clomazone, symetryne, the not same-action machine of three kinds of herbicides of S-metolachlor
Reason, three is compounded, synergistic effect has been reached.
Beneficial effects of the present invention：
1. the Herbicidal combinations that the present invention is provided, rationally, herbicidal effect is good, and drug cost is low for component, and its activity and weeding effect
Fruit is not the simple superposition of each component activity, but has significant synergistic effect, can expand control of weeds spectrum, to crop safety
It is good, meet the security requirement of pesticidal preparations, while reducing times for spraying, reduce drug cost.
2. the Herbicidal combinations that the present invention is provided, three kinds of active component mechanism of action are not quite identical, it can overcome long-term
The single shortcoming using easily generation resistance, delaying drug resistance extends the service life of medicament, and the comprehensive regulation to Weed Resistance has
Significance.
3. the present composition can be made into missible oil, dispersible oil-suspending agent or aqueous suspension agent, the selection of auxiliary material and formulation is carried
High drug effect.
