As can be seen from Table 19, can effectively prevent and treat cabbage pieris after bromine worm Benzoylamide is compounding with active component B, prevention effect is superior to 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, after bromine worm Benzoylamide and thiocyclam, dimehypo, Cupric sulfate are compounding to the preventive effect of the common insect pests such as the striped rice borer in various crop, yellow rice borer, rice leaf roller, thrips, leafhopper, pachydiplosis oryzae, plant hopper, aphid, red spider, caterpillar, leaf miner, beet armyworm, diamondback moth, Pieris rapae, tea geometrid all more than 95%, being better than single dose preventive effect, potentiation is obvious.
