Pesticide composition containing etoxazole and fenpropathrin

Abstract

The invention relates to a synergistic pesticide composition, in particular to a pesticide composition containing etoxazole and fenpropathrin in a synergistically effective amount. In the pesticide combination, the weight ratio of the etoxazole and the fenpropathrin is preferably 20:1-1:1, more preferably 11:4-11:7, further preferably 11:5-11:6 and most preferably 11:5.

Description

technical field

[0001] The invention relates to a synergistic pesticide composition, in particular to a synergistic pesticide composition comprising etoxazole and fenpropathrin and the use of the synergistic pesticide composition for preventing and treating citrus spider mite. Background technique

[0002] Citrus tree spider mite damage is generally not serious before the mid-1950s. Since chemical pesticides have been widely used in the control of citrus pests, their harm has become increasingly serious, and they have become one of the most important pests that seriously threaten citrus production, and the cost of control has also increased year by year. Adults, nymphs and larvae of red spider mites on citrus trees can all be harmful. They pierce leaves, green branches and fruit epidermis with their mouthparts, making the whole leaves gray and the pedicles damaged, causing fruit drop, especially before and after flowering in March every year. When it happened, it caused the...
