Abstract

The mixed oily suspension for high-efficiency killing of mite and insect is prepared from two existing agricultural insecticides, tetramiticide and organophosphorus insecticide, through breaking, homonegization and dispersion in non-aqueous medium, and features higher toxicity to mite, high effect up to over 90% to mites of cotton, orange, apple, vine and peach, quick action, and durable effective period.

Description

High-effective oil suspended mixture for killing mites and pests
The present invention relates to a kind of agrochemical composition, exactly a kind of high-effective oil suspended mixture for killing mites and pests.
Four mite piperazines are selectivity miticides, and the Panonychus citri on the crops such as cotton, fruit tree is belonged to and children, effective as if mite and ovum, and the lasting period is long, but to becoming the mite weak effect, quick-acting is poor, to other insect nearly unavailable.The only effective to the one-tenth mite mostly of acaricidal action arranged in the organophosphorus insecticide, and to the ovum weak effect, the lasting period is also short, but has good quick-acting.Both are composite, have complementary advantages, be one of acaricidal approach of design ideal.
The objective of the invention is to provides a kind of desirable efficient mite mixture that kills by complex process for the mite pest of effectively killing in the crops.
Four mite piperazines are the former powder of solid, and are water insoluble, also are insoluble to most of organic solvents, generally are processed into suspending agent or wetting powder and are used for farmland and orchard.The phosphoric acid ester insecticide mostly is liquid crude greatly, can be dissolved in multiple organic solvent, but poor at water stability, very easily degraded.Therefore, oil-suspending agent is both composite optimal selections.Oil-suspending agent is the stable suspension system of high dispersive that one or more pesticide active ingredients (wherein having a kind of former medicine of solid that is at least) form in non-aqueous media.
The present invention is achieved in that
With former powder of four mite piperazines and part of auxiliary, solvent reaches the fineness (≤3 μ m) that suspends and require by ultra-fine grinding, this crushing process is finished in sand mill or sand milling still, clofentezine suspension agent after will pulverizing then is dispersed in the non-aqueous media (calling solvent in the following text) together with selected organophosphorus insecticide crude oil, surfactant, antisettling agent, stabilizing agent, and this dispersion process is finished in the homogeneous blender.
In oil suspension mixture, four mite piperazine active constituent contents are 5~25% (percentage by weights, down together), the organophosphorus insecticide active constituent content is 5~609%, and dosage of surfactant is 1~15%, and the antisettling agent consumption is 0.5~5%, stabilizing agent dosage is 0.5~2%, and surplus is a solvent.
Described organophosphorus insecticide can be one or both lethanes in nuvacron, dichlorvos, omethoate, Rogor, Hostathion, isocarbophos, chlopyrifos, chlorpyrifos-methyl, Toyodan, the acephatemet, and total active constituent content is 5~60%.
Described surfactant can be one or both mixed surfactants in alkylbenzenesulfonate, castor oil polyoxyethylene ether, styryl phenyl APEO, the styryl phenol formaldehyde resin polyoxyethylene polyoxypropylene block co-polyether, and total consumption is 1~45%.
Described antisettling agent can be a kind of in white carbon, bentonite, the attapulgite, and consumption is 1~5%.
Described stabilizing agent can be a kind of in triphenyl phosphite, urea, the alkyl phosphoric acid ester derivative, and consumption is 0.5~2%.
Described solvent can be one or both mixed solvents in vegetable oil, senior fatty hydrocarbon ils, aromatic hydrocarbon, ethylene glycol, the glycerine.
The present invention's oil suspension mixture outward appearance is a peony suspension, and the physicochemical property of preparation and every technical indicator all meet the standard of relevant agricultural chemicals suspension agent.
The present invention's oil suspension mixture can be used for control evil mite on the crops such as cotton, fruit tree, and can doublely control other insects.
Indoor toxicity test result to female one-tenth mite of Tetranychus cinnabarinus and ovum shows, four mite piperazines and organic phosphor desinsection miticide mix the summation action that act as each single agent that is paired into mite, but the virulence to the Tetranychus cinnabarinus ovum has certain synergistic effect, co-toxicity coefficient is between 138~245, changes to some extent along with the difference of organophosphorous pesticide and proportioning.
Field trial shows, the present invention's oil suspension mixture to the harmful mite on the crops such as cotton, citrus, apple, grape, peach have higher preventive effect, its preventive effect multipotency reaches more than 90%, and lasting period that has very strong quick-acting and grow.
Below be described in detail embodiments of the invention.
