Can find out that by table 3 can effectively prevent and treat the tomato Bemisia tabaci behind thiophene worm amine and the high-efficient lambda-cyhalothrin compound, control efficiency all is superior to the preventive effect of single agent.In the test scope of medication, the target crop is had no adverse effects; Behind thiophene worm amine and high-efficient lambda-cyhalothrin compound to the control efficiency of aphid, leafhopper, thrips, plant hopper, tea lesser leafhopper, tea geometrid, rice water weevil, leaf miner, peach fruit borer, two spotted spider mite, Americal rice leaf miner, diamond-back moth, beet armyworm, cabbage caterpillar, cotton bollworm more than 95%; Control efficiency is superior to the preventive effect of single agent, and good synergistic effect is arranged.
Application implementation example five thiophene worm amine and the ether chrysanthemum ester and the composite control wild cabbage beet armyworm test of pesticide effectiveness thereof
This EE is in Ningcheng County, Chifeng City, the Inner Mongol, and test medicine is researched and developed, provided by Shaanxi agricultural chemicals Co., Ltd of U.S. nation, contrast medicament 50% thiophene worm amine water dispersible granules (commercial), 10% ether chrysanthemum ester suspending agent (commercial).
Investigation wild cabbage beet armyworm insect pest index in the dispenser of insect pest initial stage of origination, was investigated the insect pest indexes in 24 hours, 72 hours after the dispenser and is calculated preventive effect before the medicine.Experimental result is as follows:
Table 4 thiophene worm amine, ether chrysanthemum ester and the composite control wild cabbage beet armyworm test of pesticide effectiveness thereof
Can find out that by table 4 can effectively prevent and treat the wild cabbage beet armyworm after thiophene worm amine and ether chrysanthemum ester are composite, control efficiency all is superior to the preventive effect of single agent.In the test scope of medication, the target crop is had no adverse effects; After thiophene worm amine and ether chrysanthemum ester are composite to the control efficiency of Bemisia tabaci, aphid, leafhopper, thrips, plant hopper, tea lesser leafhopper, tea geometrid, rice water weevil, leaf miner, peach fruit borer, two spotted spider mite, Americal rice leaf miner, diamond-back moth, cabbage caterpillar, cotton bollworm more than 95%; Control efficiency is superior to the preventive effect of single agent, and good synergistic effect is arranged.
