Embodiment 1

[0038]

[0039] Weigh the original drug of pyriproxyfen, the original drug of pyridinequinazoline and the corresponding auxiliary agents according to the mass ratio, and adopt wet granulation to obtain the water-dispersible granules of the present invention after pulverization, mixing, granulation and sieving .

[0040] In this embodiment, the mass ratio of pyriproxyfen and pyridinequinazoline can be changed between 50:1-1:50, and the total mass percentage of the two is still 51%, forming a new embodiment.

Embodiment 2

[0042]

[0043] Weigh the original drug of pyriproxyfen, the original drug of pyridinequinazoline and the corresponding auxiliary agents according to the mass ratio, and then obtain the wettable powder of the present invention through the processes of mixing, grinding and mixing of fillers, original drugs and auxiliary agents .

[0044] In this embodiment, the mass ratio of pyriproxyfen and pyridinequinazoline can be changed between 50:1~1:50 (example 50:1, 10:1, 1:1, 1:10, 1:50), The total mass percentage of the two is still 51%, forming a new embodiment.

Embodiment 3

[0046]

[0047] Take the former medicine of pyriproxyfen, the former medicine of pyridinequinazoline and emulsifier, solvent according to the mass ratio, put the former medicine of pyriproxyfen, the former medicine of pyridinequinazoline, and most of the xylenes into the preparation kettle, start the stirrer to mix, and Dissolve the original drug in the solvent under stirring; after the original drug is completely dissolved (cooling is required if the temperature is high), add Nongru 600#, Nongru 2000# and the remaining solvent to continue mixing. When the temperature is lowered to room temperature, the emulsifiable concentrate preparation of the present invention is obtained.

[0048] In this embodiment, the mass ratio of pyriproxyfen and pyridinequinazoline can be changed between 50:1~1:50 (example 50:1, 10:1, 1:1, 1:10, 1:50), The total mass percentage of the two is still 22%, forming a new formulation example.

Abstract

The invention discloses an insecticide composition containing pyriproxyfen. The composition is composed of effective components of pyriproxyfen and quinazoline or auxiliaries or solvents or carriers, wherein the mass ratio of the effective components of pyriproxyfen to quinazoline is 50:1-1:50, and the total mass percentage content of the effective components is 1-80%. The composition has the remarkable synergistic effect, drug resistance of injurious insects is overcome and delayed, the environmental compatibility is good, and the insecticide composition has an efficient effect on small injurious insects such as aleyrodid, thrips, scale insects and aphid causing serious damage and is safe.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing pyriproxyfen and its application for preventing and controlling crop pests, and belongs to the technical field of agricultural insecticides. Background technique [0002] As we all know, small pests such as whiteflies, planthoppers, thrips, psyllids, and scale insects have the characteristics of small size, fast reproduction, hidden hazards, etc., and are very easy to develop drug resistance. Some commonly used agents have no systemic effect (such as spinosad) or have high resistance (such as neonicotinoids) despite systemic effect, and the actual application effect in the field is not ideal; on the other hand, the current agricultural production Adults / nymphs are mainly used as control targets, and chemical agents with ovicidal effect are rarely involved. Therefore, the control of small pests is in great need of new chemical agents that can c...
