Abstract

The invention discloses an insecticidal composition and a preparation thereof. The insecticidal composition comprises spirotetramat and one ingredient selected from nitenpyram, chlopyrifos, acetamiprid or imidacloprid. The results of field control experiments show that compared with a single dose of spirotetramat, the insecticidal composition and the preparation has obvious synergistic action.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an insecticidal composition and its preparation. Background technique [0002] Rice planthopper, insect class Homoptera planthopper pests, commonly known as fire midges, damage rice and other crops by piercing and sucking plant juice. [0003] Aphids, also known as honey bugs, greasy insects, etc., mostly belong to the family Aphididae of the order Homoptera, and are pests with piercing and sucking mouthparts. They often cluster on leaves, tender stems, flower buds, terminal buds, etc., sucking juice and causing leaves to shrink. , curly, deformed, causing branches and leaves to wither or even the death of the whole plant in severe cases. The honeydew secreted by aphids can also induce soot, viral diseases and attract ants. [0004] Scale insects are insects of the order Homoptera. Most worms are equipped with a wax paper secretion, the scale. Scale insects are the most co...
