Abstract

An insecticiding and miticiding composite agricultural chemical contains propargite (10-90 vol.%), abamectin (0.2-50%), solvent and assistant. Its advantages are high effect and low poison.

Description

The compounded miticide agricultural chemicals

Technical field

What the present invention relates to is a kind of compounded miticide agricultural chemicals that is formed by two kinds of combination of active principles.

Background technology

Alkynes mite spy is a kind of miticide farm chemical of the U.S. favourable incoming road chemical industrial company initiative, and commercially available agricultural chemicals commodity are called " propargite ", is applied rapidly with its low toxicity, high activity with advantage such as environment friendliness.But its cost is higher, and the young tender part of crop is easily produced poisoning, makes large-area applications be subjected to certain limitation.

Avermectin is the product by Canadian first synthetic of scientist, high to evil mite insect activity, various pests also there is preventive effect preferably, good with the compatibility of aquatic organisms such as environment, people and animals, natural enemy, fish, and degradability is good, is difficult for residual, it is a kind of comparatively desirable biopesticide that develops at present in the pollution-free food process, but also have cost also higher, the lasting period is shorter, and rate of knockdown waits weak point slowly.

Both keeping above-mentioned two kinds of agricultural chemicals advantage separately for reaching, can overcome again its existing separately still can not satisfactory part, addressing the above problem, at present both at home and abroad respectively with above-mentioned two kinds of agricultural chemicals serve as basis preparation composite insecticide aspect, done a large amount of explorations and work.For example, once carried out composite with Multiple Pesticides such as water amine phosphorus, hexythiazoxs respectively to alkynes mite spy; Also once carried out composite with Multiple Pesticides such as phoxim, beta-cypermethrin, Hostathions respectively to Avermectin.But these work are seen so far as yet breakthrough progress is not arranged, the problem and shortage of above-mentioned existence is not yet found gratifying solution always.

Summary of the invention

At above-mentioned situation, the compounded miticide agricultural chemicals of the new model that it is active ingredient that the present invention will provide more than one to state two kinds of agricultural chemicals, and prove by result of the test, the agricultural chemicals of this composite form can be implemented under the prerequisite that had both kept above-mentioned two kinds of agricultural chemicals advantage separately, has successfully overcome it again from existing problem and shortage.

Special and Avermectin is an active ingredient to compounded miticide agricultural chemicals of the present invention with the alkynes mite, the consisting of of its percent by volume:

The special 10-90 of alkynes mite, Avermectin 0.2-50, all the other are to allow to use and acceptable solvent and auxiliary component in agricultural chemicals.

Above-mentioned compounded miticide agricultural chemicals of the present invention, owing to oozing property in tagging property that has made full use of alkynes mite spy and the Avermectin, thereby produced the beyond thought effect that drug effect is multiplied, and therefore can reach under the prerequisite of effect same, the consumption of agricultural chemicals is significantly reduced, thereby solved above-mentioned two kinds of pesticide cost height satisfactorily, and special knocking down of poisoning and the Avermectin problem slow and that the lasting period is short that easily produces of alkynes mite.

In above-mentioned compounded miticide agricultural chemicals, complementary compositions such as said solvent, auxiliary agent can use according to the corresponding formulations of pesticide.For example, can comprise emulsifier as fatty alcohol-polyoxyethylene ether (n=10) commonly used in the present agricultural chemicals, agricultural newborn 200# (fatty alcohol-polyoxyethylene ether), agricultural newborn 1600-1 (phenethyl phenyl polyoxyethylene polyoxypropylene ether), farming breast 656 various ways such as (compounds of phenethyl phenyl APEO and calcium dodecyl benzene sulfonate); The solvent that dimethylbenzene, water etc. are commonly used; Fillers such as silica, white carbon, wood powder, ammonium chloride, starch, and other auxiliary component such as xanthans, dodecyl Maalox Antacid and antifreezing agent propane diols.

When adopting the compounded miticide agricultural chemicals of the above-mentioned form of the present invention, on the basis that above-mentioned active ingredient is formed, can be by the conventional preparation method of present pesticide producing, be made into the various formulations of pesticide of practical use form, as the formulations of pesticide of the routine of the missible oil that is mixed with in the usual way, emulsifiable concentrate, colloidal suspending agent form.

Below, again foregoing of the present invention is described in further detail by the embodiment of some example forms.But this should be interpreted as that the scope of the above-mentioned theme of the present invention only limits to following example.All technology that realizes based on foregoing of the present invention all belong to scope of the present invention.

Embodiment

As the concrete composition of some embodiment of the compounded miticide agricultural chemicals of the above-mentioned composition form of the present invention, as shown in table 1.Wherein, used raw material alkynes mite agricultural chemicals 73% propargite missible oil (EC) special and that contrast is used as drug effect is commercial by the U.S. favourable incoming road chemical industrial company product in 2000 in the agricultural chemicals of the present invention; What used raw material Avermectin and contrast is used as drug effect agricultural chemicals 1.8% abamectin emulsifiable concentrate (EC) were also all commercial in the agricultural chemicals of the present invention is just reaching earlier crop protection Co., Ltd product in 2000 by Switzerland.

Listed each routine different dosage form form agricultural chemicals in the table 1 respectively by given constituent, forms by conventional preparation method's mixed preparing of corresponding formulation agricultural chemicals.

With above-mentioned each the routine agricultural chemicals of the present invention and commercially available 73% propargite (trade name, active ingredient are alkynes mite spy) missible oil and two kinds of agricultural chemicals of 1.8% abamectin emulsifiable concentrate, the comparative test result of some control in field drug effects of carrying out, as shown in table 2.
