Abstract

The invention relates to a dinotefuran-containing pesticide belonging to the field of agricultural insecticides. The dinotefuran-containing pesticide comprises effective ingredients of dinotefuran and chlorpyrifos with the weight ratio of (1:50)-(50:1), wherein the total weight of the dinotefuran and the chlorpyrifos accounts for 1-50 percent of the pesticide. The dinotefuran-containing pesticide is capable of controlling multiple kinds of insect pests, and has a remarkable synergism; an insecticidal spectrum is enlarged, the pesticide dosage is reduced, the residual quantity of the pesticide on crops is lowered, and the environmental pollution is lightened. The dinotefuran-containing pesticide has relatively high activity on rice planthoppers, rice leaf folders and striped rice borers, is safe to people and livestock, and is good in environment consistency; the pests hard generate pesticide resistance.

Description

A kind of insecticide containing MTI-446

Technical field

The invention belongs to the agricultural insecticide field, relate to a kind of production technical field of composite insecticide.

Background technology

The different cultivars composition carries out composite, is the very common method of control resistant insect.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals is all additive effect, and the seldom composite of synergistic effect really arranged, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Through inventor's research, find to produce good synergistic effect after MTI-446 and chlorpyrifos mixture, and not yet open about the microemulsion relevant report of MTI-446 and chlorpyrifos mixture.

Summary of the invention

The present invention aims to provide a kind of compounded pesticides, and by composite, the expanding prevention scope, improve control efficiency, reduces dosage and agricultural cost.

Technical scheme of the present invention is: active ingredient is MTI-446 and chlopyrifos, and the mass ratio of described MTI-446 and chlopyrifos is 1: 50～50: 1, and MTI-446 and chlopyrifos adduction gross mass account for 1%～50% of described insecticide.

Beneficial effect of the present invention is: it can prevent and treat multiple insect pest, and has obvious synergistic effect, and has enlarged insecticidal spectrum, and rice fulgorid, rice leaf roller, striped rice borer are had to greater activity; And reduced the agricultural chemicals dosage, reduced the residual quantity of agricultural chemicals on crop, alleviated environmental pollution; , insect good to person poultry safety, Environmental compatibility is difficult for developing immunity to drugs.

The present invention has overcome degradation problem under the resistance generation that the long-term use of MTI-446 single dose may bring, drug effect, the invention has the advantages that:

1, after MTI-446 and active component chlorpyrifos mixture, there is notable synergistic and lasting effect;

2, the present invention has enlarged insecticidal spectrum, and to rice fulgorid, rice leaf roller, striped rice borer, coleopteran pest, lepidoptera pest, as diamond-back moth, beet armyworm, fruit tree mites etc. all have greater activity;

3, adopt the present invention, reached the dosage that reduces agricultural chemicals, reduce the residual quantity of agricultural chemicals on crop, alleviate the purpose of environmental pollution;

4, the present invention, insect good to person poultry safety, Environmental compatibility is difficult for developing immunity to drugs.

Representative formula of the present invention is: MTI-446, chlopyrifos, emulsifier, dimethylbenzene and n-butanol account for respectively 5.0%, 25.0%, 15%, 5% and 2% of insecticidal preparation gross mass, and all the other are water.

The advantage of this formula:

1, synergistic effect is obvious: MTI-446 and chlorpyrifos mixture are prevented and treated the proportioning of rice hoppers: when the proportioning of MTI-446 and Avermectin, during at 1: 5, synergistic effect is more obviously outstanding, its co-toxicity coefficient maximum, and synergistic effect is the most obvious.

2, the environmental protection type agricultural chemical that has development prospect: 30% MTI-446 chlorpyrifos micro emulsion is characterized in take that water is as medium, containing or less containing organic solvent, thereby do not fire not quick-fried, production operation, storing is safe, low in the pollution of the environment, saves a large amount of organic solvents; The pesticide dispersion degree is high, reaches the miniaturization degree, and the agricultural chemicals particle is generally 0.1～0.01 micron, and outward appearance is similar to transparent or sub-translucent liquid; Good dispersion in water is strong to the target body permeability, adhesive force good.Microemulsion also belongs to the non-solvated formulation of liquid pesticide formulation, is rising novel form, and the trend that replaces gradually traditional missible oil is arranged.

Embodiment

One, the method for preparing 30% MTI-446 chlorpyrifos micro emulsion:

Take respectively MTI-446 5kg, chlopyrifos 20 kg, emulsifier 15 kg, dimethylbenzene 5 kg, n-butanol 2kg, and appropriate amount of deionized water.

First MTI-446, chlopyrifos, emulsifier, dimethylbenzene, n-butanol are added in blender, then add deionized water, take and reach gross mass as 100kg, then, through fully mixing, make 30% MTI-446 chlorpyrifos micro emulsion.

Two, use in field:

1, application process, dosage:

This product should be used in rice fulgorid nymph peak period, and every mu with this product 25～30g, is watered even spraying after 50kg.

2, carry out the field efficacy comparative trial of 30% MTI-446 chlorpyrifos micro emulsion and 40% chlorpyrifos ec, 20% MTI-446 water dispersible granules:

In paddy rice, in booting stage, 2 generation rice fulgorid low age nymph peak periods (August 9) difference medications once.Before medicine (August 9) look into radix, respectively investigate one time the worm amount after medicine August 10,12 days, 16 days, 24 days.10 points are looked in every community, look into 2 caves at every, put down in writing respectively total worm amount of white-backed planthopper, brown planthopper, the calculation correction preventive effect, and preventive effect is carried out to significance test of difference, see the following form:

As seen from the above table: the 30% MTI-446 chlorpyrifos micro emulsion formed after MTI-446 and chlorpyrifos mixture can effectively be prevented and treated to rice hoppers, and control efficiency all is better than the preventive effect of single dose.In the test scope of medication, the target crop is had no adverse effects, and Yellow Rice Borer, rice leaf roller are also had to good preventive effect.
