Embodiment 1

[0047] The present invention contains the emulsifiable concentrate preparation of the high-efficiency insecticide of nitenpyram, allethrin and benzoylurea, and concrete composition is as follows (every part 1000g):

[0048] Nitenpyram: 10 parts; Allethrin: 20 parts; Benzoylurea: 20 parts.

[0049] The specific production steps of the emulsifiable concentrate preparation are first adding the active ingredients nitenpyram, allethrin, and benzoylurea into the solvent according to the conventional procedures in the field to completely dissolve them, then adding emulsifiers and synergists and stirring evenly to form a uniform and transparent The oily liquid can be filled into the emulsifiable concentrate preparation of the composition of the present invention.

Embodiment 2

[0051] The present invention contains the suspending agent of the high-efficiency insecticide of nitenpyram, allethrin and benzoylurea, and concrete composition is as follows (every part 1000g):

[0052] Nitenpyram: 50 parts; Allethrin: 40 parts; Benzoylurea: 60 parts.

[0053] The specific production steps of this suspending agent are the conventional suspending agent preparation method in the art, first other auxiliary agents (dispersant, antifreeze agent, thickener, defoamer, penetration enhancer and pH value regulator) are mixed, Shear and mix evenly, add the active ingredients nitenpyram, allethrin and benzoylurea, and grind the balls in a ball mill for 2 to 4 hours, so that the particle diameters are all below 5mm, and the composition of the present invention can be prepared suspension formulations.

Embodiment 3

[0055] The present invention contains the water dispersible granule of the high-efficiency insecticide that nitenpyram, allethrin and benzoylurea have, and concrete composition is as follows (every part 1000g):

[0056] Nitenpyram: 35 parts; Allethrin: 30 parts; Benzoylurea: 40 parts.

[0057] The specific production steps of the water-dispersible granules are the conventional preparation methods of water-dispersible granules in the art: according to the above formula, the active ingredients nitenpyram, allethrin, benzoylurea dispersant, wetting agent, disintegration The agent and the filler are mixed evenly, pulverized with an ultra-fine jet mill, kneaded, and then added to a fluidized bed granulation dryer for granulation, drying, and sieving. After sampling and analysis, the water content of the composition of the present invention can be made. Dispersible granules.

[0058] The medicaments prepared in Examples 1-3 of the present invention were tested in a field, and their...

Abstract

The invention relates to an efficient pesticide composition used for killing agricultural pests. The efficient pesticide composition comprises the following components in parts by weight: 10-50 parts of nitenpyram, 20-40 parts of allethrin, and 20-60 parts of benzoylurea. The efficient pesticide composition has the advantages that the pesticide composition has obvious synergism, can be lower in usage amount of effective components and in use cost, delays drug resistance of pests, effectively reduces environmental pollution and pesticide residue, and has remarkable killing effect on trialeurodes vaporariorum, aphid, pear psylla, leafhopper, thrips, and indoor mosquitoes and flies, as well as parasitic mite and tick harmful to livestock, and can reduce damage to environment.

Description

technical field [0001] The invention relates to the field of insecticides used for the control of agricultural pests, in particular to a high-efficiency insecticide containing nitenpyram, allethrin and benzoylurea. Background technique [0002] The residues of pesticides in agricultural products and the toxicity to animals have always been a hot spot of concern. [0003] Nitenpyram: [0004] Chemical name: (E)-N-(6-chloro-3-pyridylmethyl)-N'-methyl-2-175 vinylidene diamine. [1] [0005] English common name: Nitenpyram [0006] Chemical name: (E)-N-(6-chloro-3-pyridylmethyl)-N-ethyl-N′-methyl-2-nitroethylenediamine [0007] Structural formula: [0008] [0009] Nitenpyram belongs to nicotinimides, and it is another new product developed in Japan after imidacloprid and acetamiprid. It has excellent systemic property, osmotic effect, wide insecticidal spectrum, safe and non-toxic. It is a replacement product for controlling piercing-sucking mouthparts pests such as wh...
