Problems solved by technology

[0005] In recent years, the piercing-sucking mouthparts pests on crops have caused serious damage. Farmers have developed severe resistance to drugs such as imidacloprid, bifenthrin, and chlorpyrifos for a long time. There have been problems of increasing the dosage of drugs and poor control effects, and the environmental pollution has also tended to serious

Embodiment 1

[0023] Example 1: 30% thiacloprid·chlorfenapyr water-dispersible granules.

[0024] Weigh 10% of the original drug of thiacloprid, 20% of chlorfenapyr, 1% of saponin powder, 5% of sodium lignosulfonate, 5% of ammonium sulfate, and 5% of light calcium carbonate, mix the above raw materials, and stir well The mother powder is obtained through the jet mill, and the mother powder is mixed with 2% polyvinylpyrrolidone evenly, and then made up to 100% with kaolin, and then granulated, dried, and sieved to obtain 30% thiacloprid · chlorfenapyr water dispersion granules. The content of active ingredients after inspection is 10% thiacloprid, 20% chlorfenapyr, suspension rate≧75%, moisture≦2.5%, pH 7.2, particle size range (225~800um)≧98%, dispersibility≧85%, Wetting time≦90s, wet sieve test (through 75um sieve)≧98, long-lasting foaming property (after 1min)≦12ml, qualified for accelerated thermal storage stability.

Abstract

The invention discloses a synergistic pesticide composition containing thiacloprid and chlorfenapyr. The weight percentage of thiacloprid in the composition is 1% to 50%, and the weight percentage of chlorfenapyr is 5% to 80%. The synergistic pesticide composition is suitable for controlling insects with piercing-sucking mouthparts in rice, vegetables, fruit trees, flowers and lawns. The two effective components in the composition have a significant synergistic effect, so that the pest control effect is improved and the pesticide consumption is reduced. The generalization and application of the synergistic pesticide composition brings great economic and social benefits.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to a synergistic insecticidal composition containing thiacloprid and chlorfenapyr, which is used for controlling piercing-sucking mouthparts pests such as rice, vegetables, fruit trees, flowers and lawns. Background technique [0002] Thiacloprid is a new broad-spectrum insecticide with high efficiency against piercing-sucking mouthparts. According to different crops, pests and application methods, the dosage is 50.4-100.8g a.i. / hm 2 . Field trials have shown that thiacloprid has excellent control effects on important pests on tea trees, pome fruits, cotton, vegetables and potatoes. In addition to being effective against aphids, whiteflies, thrips, it is also effective against various beetles (such as potato beetle, apple weevil, rice weevil) and Lepidoptera pests such as leafminer and codling moth on apple trees, And it is applicable to all corresponding crops. [0003] Thiacloprid...
