Description
Technical field
The invention belongs to technical field of pesticide, relate to the application of a kind of composition pesticide on crop evil mite.
Technical background
Acequinocyl (acequinocyl) chemical name: 2-(acetoxyl group) 3-dodecyl-1,4-naphthoquinone, molecular formula: C
24h

Investigation apple Tetranychus urticae damage index of spider mites before medicine, in the dispenser of mite evil initial stage of origination, 10 days, 30 days, 45 days investigation damage index of spider mites after dispenser also calculate preventive effect.Result of the test is as follows:
Table 19 acequinocyl and active component B and the composite control apple Tetranychus urticae test of pesticide effectiveness thereof
As can be seen from Table 19, acequinocyl and active component B composite after can effectively prevent and treat apple Tetranychus urticae, control efficiency is all better than the preventive effect of single dose, and the preventive effect phase is long.In test scope of medication, target crop is had no adverse effects.
After draw through tests different local throughout the country, acequinocyl and pyridaben, propargite, the composite rear preventive effect to the common mite evil such as the two spotted spider mite on crops, Panonychus citri, tetranychus viennensis, Tetranychus urticae, yellow spider, knurl tick, blister mite, Shenmu-Yanan railway, Tetranychus cinnabarinus, tealeaves mite, tomato goitre mite, rust mite, cotton spider mites, tetranychus telarius of Bifenazate are all more than 95%, be better than single dose preventive effect, synergistic effect is obvious.
