Problems solved by technology

However, the development cost of new active ingredients is high, the development cycle is long, and it can never keep up with the speed of weed resistance
Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

Embodiment 1

[0035] Example 1: 30% lufenuron · propargite EC

[0036] Its components are: lufenuron, 2%; propargite, 28%; emulsifiers choose Nongru 500# and Nongru 600#, the dosage is 3% and 6% respectively; solvent chooses cyclohexanone, 8%, Xylene, balance.

Embodiment 2

[0037] Example 2: 42% lufenuron · propargite EC

[0038]Its components are: lufenuron, 2%; propargite, 40%; emulsifiers choose Nongru 500# and Nongru 600#, the dosage is 3.3% and 5.7% respectively; solvent chooses cyclohexanone, 8%, Xylene, balance.

[0039] The preparation method of the emulsifiable concentrate in Examples 1-2 is as follows: according to the mass percentage of each component in the examples, the active ingredients lufenuron and propargite are added to the carrier, and surfactants and other functional auxiliaries are added therein , Stir and mix evenly in a stirring mixing tank. The stirring and mixing kettle can be enamel reaction kettle, stainless steel stirring kettle, etc.

Embodiment 3

[0040] Example 3: (22% lufenuron·propargite microemulsion)

[0041] Its components are: lufenuron, 2%; propargite, 20%; emulsifier KT and Nongru 600#, the dosage is 7% and 8% respectively; solvent, cyclohexanone, 5%; water, remaining quantity.

Abstract

The invention belongs to the field of pesticide, in particular to an insecticidal composition for preventing and treating agricultural pests and a purpose of the insecticidal composition. The insecticidal composition has active ingredients such as lufenuron and propargite, wherein the mass ratio of lufenuron to propargite as the active ingredients is 1:(6-20), and is preferably 1:(10-16). Besides the lufenuron and the propargite as the active ingredients, the insecticidal composition also comprises agricultural preparation auxiliary ingredients so that the insecticidal composition is made into missible oil, microemulsion or water emulsion. The insecticidal composition is mainly used for preventing and treating lepidopteran pests and mite pests. The insecticidal composition prepared by the invention has the advantages that the synergia effect is obvious, and the medicine effect is greatly improved; the effect taking time is long, the field consumption of active ingredients is reduced, the production and use cost is reduced, and the environment pollution is reduced; and the pest drug resistance generation is favorably overcome and delayed, and the insecticidal composition belongs to an important measure for preventing and treating field pests.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticidal composition for preventing and controlling agricultural pests and its application. Background technique [0002] Lufenuron, English name Lufenuron, chemical name N-[[2,5-dichloro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl]amino]carboxyl]-2 ,6-Difluorobenzamide. It is a benzoylurea acaricide insecticide and a chitin synthesis inhibitor. Its insecticidal mechanism is to kill pests by acting on insect larvae and preventing the moulting process. It has a unique effect on most pests that need to molt and lay eggs. Especially it has excellent control effect on leaf-eating caterpillars such as fruit trees, and has a unique killing mechanism on thrips and rust mites, and is suitable for controlling pests resistant to synthetic pyrethrins and organophosphorus pesticides. The long-lasting effect of the pesticide is beneficial to reduce the number of spraying; it is safe for crops ...
