Field trial embodiment four:
Test method: with reference to " NY/T1464.8-2007 pesticide field efficacy medicine test criterion the 8th part: bactericidal agent for preventing and treating tomato virus disease ".First time spray pesticide is carried out, interval 7 days second time dispenser when tobacco mosaic virus disease just occurs.Within 7 days, 14 days, carry out classification investigation respectively before dispenser and after second time medicine, 7 days, 14 days disease indexs and preventive effect after calculating second time medicine, the results are shown in Table 8:
The field test results of tobacco mosaic virus disease prevented and treated by table 8
From result of the test table 8, when usage amount is lower than single dose, the control efficiency of bactericidal agent for preventing and treating tobacco mosaic virus disease of the present invention is still obviously better than single dose.Control efficiency (the active ingredient dosage 9g/667m of each process 7d after second time medicine
2) respectively than single dose poison fluorine phosphorus (active ingredient dosage 12g/667m
2) and pungent bacterium amine acetate (active ingredient dosage 12g/667m
2) control efficiency height 20.58%-27.36%, 26.83%-33.62%; And still can reach the preventive effect of more than 89% at 14d, the lasting period is long.
