通过室内毒力测定和田间药效试验,评价了乙蒜素乳油、丙森锌可湿性粉剂对虚幻球藻Apatococcus lobatus的毒力及防治效果。结果表明,80%乙蒜素乳油对虚幻球藻较敏感,EC50为73.419 0mg/L。其1 000倍液喷施一次的田间防效达99.5%。70%丙森锌可湿性粉剂对虚幻球藻不太敏感,其500倍液连喷3次的田间防效仅为47.8%。 Through indoor toxicity test and field efficacy test, the toxicity and preventive and curative effect of ethylicin, Cicerin wettable powder on Apatococcus lobatus were evaluated. The results showed that 80% allicin EC was sensitive to Phaeocystis globosa, EC50 was 73.419 0 mg / L. Its 1 000 times the spraying of a field control effect of 99.5%. 70% propane zinc wettable powder is not very sensitive to Phaeophycia, and its field efficacy of spraying 500 times and even spraying three times is only 47.8%.
