Abstract

The present invention relates to a pesticide preparation with high efficiency, low toxicity and strong systemic translocation, which has a special good effect on piercing-sucking pests and pests with scratching mouthparts, such as aphids, leafhoppers, plant hoppers, thrips, white flies and resistant strains. The compounded preparation provided by the present invention is a compounded preparation by compounding imidacloprid, sand worm toxin pesticide, pyrethrin pesticide, organic phosphide pesticide, carbamate pesticide and heterocyclic pesticide.

Description

Compound preparation of imidacloprid

The English name of imidacloprid: Imidacloprid

Structural formula:

Imidacloprid is a high-efficiency, low-toxicity, and systemic insecticide developed by Japan Special Pesticide Company and Bayer A.G. It is effective against piercing and sucking mouthpart pests, such as aphids, leafhoppers, planthoppers, thrips, powder Lice and its resistant strains have special effects; it also has certain control effects on Coleoptera, Diptera and Lepidoptera. Because of its systemic effect, its various dosage forms have good preventive effects.

The combination of imidacloprid and a variety of pesticides can improve the efficacy, expand the insecticidal spectrum and reduce the cost of use.

J.P.63 126804 has reported that the compound preparation of imidacloprid and cartap has obvious synergistic effect on the control of rice leaf roller.

Cartap:

The present invention proposes imidacloprid and silkworm-killing poisonous pesticides chlorchondan, dimehypo, dimetap, and thiocyanate; and pyrethroid pesticides cyhalothrin, fenvalerate, cypermethrin, and deltamethrin; With organophosphorus pesticides phoxim, chlorpyrifos, triazophos, methamidophos; with carbamate pesticides dimethoate, omethoate, memecarb, pirimicarb and heterocyclic pesticide buprofezin ( Ling) and other pesticides are compounded into more than binary insecticide preparations to improve efficacy, expand bactericidal spectrum, and reduce agricultural costs.

The invention proposes that the compound preparation of imidacloprid and silkworm poisonous pesticide dimehypo has synergistic effect on piercing and sucking mouthparts pests, and the control effect on chewing pests is also very prominent.

The imidacloprid and other insecticides proposed by the present invention can be made into powder, wettable powder, water dispersible granule, suspension, emulsion and the like.

Active ingredients of the preparation: imidacloprid accounts for 1-90% (weight percentage) in the preparation, and other active ingredients account for 90-1% (weight percentage) in the preparation.

The stabilizers used in the formulation are: citric acid, boric acid, HAC, H ₃ PO ₄ , NH ₄ Cl, (NH ₄ ) ₂ SO ₄ .

The additives used are: sodium lignosulfonate, sodium lauryl sulfate, dispersant NNO, penetrant T, agricultural milk 500 ^# , agricultural milk 600 ^# , agricultural milk 100 ^# , CMC, 1656H, 1656L9.

The fillers used in the preparation include: diatomite, attapulgite, kaolin, bentonite, CaCO ₃ NaHCO ₃ .

example 1:

25% of imidacloprid, 25% of insecticide, 6% of sodium lignosulfonate, 4% of NNO, 5% of boric acid, adding diatomaceous earth to make up to 100%, to obtain 50% wettable powder.

Example 2:

10% of imidacloprid, 10% of insecticide, Nongru 500 ^# or 600 ^# 5%, NNO4%, boric acid 10%, CMC55, add NaHCO ₃ to 100% to get 20% water dispersible granules.

Example 3:

10% of imidacloprid, 10% of cyhalothrin, 6% of sodium lignosulfonate, 5% of 1656H, 5% of NNO, and 10% of ethylene glycol were added to make up to 100% with water to prepare a 20% suspension concentrate.

Example 4:

Imidacloprid 5%, phoxim 35%, 1656L9 or 1656H6%, add xylene to make up to 100%, and make 40% emulsion.

Example 5:

Imidacloprid 5%, Memocarb 35%, Sodium Lignosulfonate 6%, NNO 4%, add kaolin to make up to 100%, and make 40% wettable powder.

Example 6:

10% of imidacloprid, 30% of buprofezin, 6% of sodium lignosulfonate, 4% of NNO, added kaolin to make up to 100%, and a 40% wettable powder was prepared.

Example 7:

20% imidacloprid, 20% thiocyanate, 6% sodium lignosulfonate, 4% NNO, 5% boric acid, add diatomaceous earth to make up to 100%, and make 50% wettable powder.

The compound preparation of the present invention has a synergistic effect on the prevention and control of sucking and sucking mouthpart pests, such as special effects on leafhoppers, planthoppers, thrips, whiteflies, Coleoptera, Diptera and Lepidoptera.

Example 8:

Imidacloprid and chlorchongdan are used in different ratios (1:1, 1:2, 1:3, 1:4, 1:5) for toxicity screening tests. If the ratio of 1:1 is used, the concentration used is 1ppm, 2ppm The control effects of 4ppm on broad bean aphid were 31.5%, 59.5%, and 82.3%, respectively, indicating that when the active substance is greater than 4ppm, there is an obvious control effect.
