Abstract
The invention discloses a micro-capsule suspension-suspending agent containing atrazine. The 100% of micro-capsule suspension-suspending agent comprises an active ingredient and the balance including a capsule wall material, an initiator, an auxiliary agent and a solvent, wherein the active ingredient is prepared by compounding the atrazine and an active ingredient II. The active ingredient II is one of alachlor, metolachlor, acetochlor, pretilachlor, propisochlor or butachlor. The micro-capsule suspension-suspending agent containing the atrazine is suitable for target crops including corns, sugarcanes, cotton, garlic, gingers, apples, bananas, citrus, hawthorns, peaches and the like, is used for preventing and controlling annual gramineous weeds, parts of broadleaf weeds and sedges, and has the advantages of being long in efficacy duration, high in work efficiency, good in synergistic effect, safe, environment-friendly and the like.
Description
Technical field
The present invention relates to technical field of pesticide, particularly a kind of microcapsule suspension-suspendinagent agent of atrazine-containing.
Background technology
Alachlor, isopropyl methoxalamine, Acetochlor, the third careless amine, propisochlor, butachlor etc. are acetamide-group herbicides, are mainly used in soil treatment, prevent and kill off grassy weed; Single dose and the multiple formulations of built agent such as missible oil, aqueous emulsion, microemulsion, wetting powder is had at present in insomnia.
Atrazine is central Shanxi plain class weed killer herbicide, Miao Qian, herbicide after seedling.Be mainly used in corn, sugarcane, Chinese sorghum, tea tree and garden and forest land and prevent and kill off annual gramineous weed and broad leaved weed.Inhibitory action is had to the perennial weed bred by rhizome or radical bud.There are being single dose and the multiple formulations of built agent such as suspending agent, wetting powder, water dispersible granules, suspension emulsion on the market at present.
At present, the conventional formulation of alachlor, isopropyl methoxalamine, Acetochlor, the third careless amine, propisochlor, butachlor, atrazine can not prevent and kill off the weeds in crop whole vegetative period by applied once also needs the weed killer herbicide that fills spray, but so just increase the cost of farmland weeding, some overlay film farmland then cannot fill spray, thus cause the underproduction, bring economic loss.In addition, the pressure that the use that people more and more focus on agricultural chemicals brings environment.In emulsifiable concentrates for agricultural chemicals, the application of a large amount of organic solvent brings serious pollution to natural environment, and the moving state of weed killer herbicide in soil relates to superficial water, particularly the pollution of underground water.Leaching is the important channel of weed killer herbicide movement in soil, causes weed killer herbicide loss to reach 5%, be generally greater than 1% by this approach.Because leaching brings problems to weed killer herbicide use: 1, the downward leaching of weed killer herbicide, cause herbicidal effect not good, and easily cause underground water residual contamination; 2, make weed killer herbicide enter crop root distribution soil layer by leaching, cause potential difference selective herbicide to injure crop; 3, reverse leaching makes weed killer herbicide move to soil table, loses by volatilizing.
Microcapsule suspension-suspendinagent agent is using macromolecular material as cyst wall or cyst membrane, by chemistry, physics or physicochemical method, liquid pesticide active ingredient encases as the capsule heart is got up, form a kind of microencapsulation with semipermeability cyst membrane, and they are disperseed using certain concentration stabilize, be suspended in as in the water of continuous phase, then be insoluble in a kind of microcapsule suspension-suspendinagent agent of active component mixing composition of organic solvent and water with another solid.Suspension-microcapsule suspension, due to the existence of cyst membrane, has following advantage:
1. oil phase and aqueous phase are separated, hydrolabil pesticide activity component, be difficult to make aqueous emulsion and microemulsion, but can be made into microcapsule formulations.
2. suppress the decomposition of the active component caused because of environmental factor (as light, heat, air, rainwater, soil, microorganism) and other chemical substances etc., improve the stability of medicament itself.
3. cyst membrane can suppress the volatility of agricultural chemicals, shelter its original peculiar smell.And the evaporation rate of volatility agricultural chemicals can be reduced, reduce the extraneoas loss caused by the volatilization of agricultural chemicals, improve the bioavailability of active ingredient.
4. introduce the function of Co ntrolled release, extend its lasting period, reduce quantity and the frequency of dispenser, improve the pressure of agricultural chemicals to environment.
5. the harmfulness of organic solvent is decreased.Many pesticide activity components, due to the physico chemical property of self, are difficult to be processed into environmentally friendly water-based aerosol, and usually can only be processed into missible oil and sell, a large amount of uses of organic solvent bring great burden to environment for human survival.The characteristics such as simultaneously organic solvent flash-point, burning-point be low give storage, transport brings very large inconvenience.
6. for the effectively composite of pesticidal active substance of multiple different performance provides great convenience.
7. poisoning is reduced.Due to the existence of cyst wall, pesticide activity component needs just can manifest its toxicity by the breakage of microcapsules or diffusion, thus can reduce the toxicity of some pesticide activity component to crop.
8. acute toxicity is reduced.Microcapsule formulations significantly can reduce pesticidal preparations product to mammiferous toxicity.
Be not difficult to find out, the above-mentioned functions of microcapsules, no matter for the Improvement and perfection of existing pesticide species, or facilitating the successful exploitation of new varieties of pesticides and apply, will be all extremely important.
