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

The complex preparation of Imidacloprid

The English name of Imidacloprid: Imidacloprid

Structural formula:

Imidacloprid is by efficient, the low toxicity of Japan special agricultural chemicals company and Bayer A.G. exploitation, the insecticide with interior absorption, to pierce-suck type, suction type mouthpart insect, as aphid, leafhopper, plant hopper, thrips, aleyrodid and resistant strain thereof special efficacy is arranged; Coleoptera, diptera, Lepidoptera also there is certain preventive effect.Because it has systemic action, its various formulations all have good preventive effect.

Composite drug effect, the expansion insecticidal spectrum of improving of Imidacloprid and Multiple Pesticides reduces use cost.

J.P.63 126804 once reported the complex preparation of Imidacloprid and cartap, and the control rice leaf roller is had the notable synergistic effect.

Cartap:

The present invention proposes Imidacloprid and kill silkworm poison class agricultural insecticide pellet, dimehypo, thiocyclam, sulphur hydrocyanic ester; With pyrethrin pesticide cyhalothrin, sumicidin, cypermethrin, decis; With organophosphorus insecticide phoxim, chlopyrifos, Hostathion, acephatemet; Become the above insecticidal preparation of binary with amino methyl class agricultural chemicals Rogor, flolimat, meta-tolyl-N-methylcarbamate (MTMC), Aphox and heterocyclic pesticide Buprofezin agriculture chemical compoundings such as (buprofezins), to improve drug effect, enlarge fungicidal spectrum, to reduce agricultural cost.

The present invention proposes Imidacloprid and killing the two complex preparations that wait of silkworm poison class agricultural insecticide has synergistic effect to pierce-suck type, suction type mouthpart insect, and also very outstanding to the preventive effect of chewing type insect.

Imidacloprid and other insecticide that the present invention proposes can be made into pulvis, wetting powder, water dispersible granules, suspending agent, emulsion etc.

The active ingredient of preparation: Imidacloprid accounts for 1-90% (percetage by weight) in preparation, and other active ingredient accounts for 90-1% (percetage by weight) in preparation.

Stabilizing agent used in the preparation has: citric acid, boric acid, HAC, H ₃PO ₄, NH ₄Cl, (NH ₄) ₂SO ₄

The auxiliary agent that is adopted has: sodium lignin sulfonate, lauryl sodium sulfate, dispersant NNO, penetrant t, farming breast 500 ^#, farming breast 600 ^#, farming breast 100 ^#, CMC, 1656H, 1656L9.

The filler that is adopted in the preparation has: diatomite, attapulgite, kaolin, bentonite, CaCO ₃NaHCO ₃

Example 1:

Imidacloprid 25%, benthiocarb 25%, sodium lignin sulfonate 6%, NNO4%, boric acid 5%, add diatomite and mend to 100%, 50% wetting powder.

Example 2:

Imidacloprid 10%, benthiocarb 10%, farming breast 500 ^#Or 600 ^#5%, NNO4%, boric acid 10%, CMC55, add NaHCO ₃To 100% 20% water dispersible granules.

Example 3:

Imidacloprid 10%, cyhalothrin 10%, sodium lignin sulfonate 6%, 1656H5%, NNO5%, ethylene glycol 10% add water and mend to 100%, make 20% suspending agent.

Example 4:

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

Example 5:

Imidacloprid 5%, meta-tolyl-N-methylcarbamate (MTMC) 35%, sodium lignin sulfonate 6%, NNO4%, add kaolin and mend, but make 40% wet-milling to 100%.

Example 6:

Imidacloprid 10%, Buprofezin 30%, sodium lignin sulfonate 6%, NNO4%, add kaolin and mend, make 40% wettable powder to 100%.

Example 7:

Imidacloprid 20%, sulphur hydrocyanic ester 20%, sodium lignin sulfonate 6%, NNO4%, boric acid 5%, add diatomite and mend, make 50% wetting powder to 100%.

Complex preparation of the present invention has synergistic effect to control pierce-suck type, suction type mouthpart insect, as leafhopper, plant hopper, thrips, aleyrodid and coleoptera, diptera, Lepidoptera are had special efficacy.

Example 8:

Imidacloprid and benthiocarb (1: 1 in varing proportions, 1: 2,1: 3,1: 4,1: 5) carry out the virulence screening test, if when adopting 1: 1 ratio, working concentration is at 1ppm, 2ppm, 4ppm is respectively 31.5% to the preventive effect of black bean aphid, 59.5%, 82.3%, tangible preventive effect when being described greater than 4ppm, active substance is just arranged.
