摘要
通过室内活性试验和田间防效试验,评价了 0.2%白藜芦醇可溶液剂对黄瓜灰霉病和番茄叶霉病的抑菌活性和防治效果,为其推广使用提供支持.试验结果表明,0.2%白藜芦醇可溶液剂300倍液对灰霉病菌和叶霉病菌的菌丝生长均具有较好的抑制活性,抑制率分别为93.5%和86.2%;田间试验中,0.2%白藜芦醇可溶液剂1 800 mL/hm2对黄瓜灰霉病和番茄叶霉病均具有良好的防治效果,持效期长达21 d,最高防效分别为90.7%和80.3%.0.2%白藜芦醇可溶液剂的防治效果与浓度相关,但其1 500mL/hm2、1 800 mL/hm2处理的田间防治效果差异不显著.
Abstract
To provide support for promotion and application of botanical pesticide resveratrol,the antibacterial activity and control effect of resveratrol 0.2%SL on grey mold and leaf mold were evaluated by indoor mycelium growth rate method and field spray method in this study.The results showed that resveratrol 0.2%SL had good inhibitory activities on Botrytis cinerea and Fulvia fulva,with the inhibitory rates of 93.5%and 86.2%,respectively.In field trials,resveratrol 0.2%SL 1 800 mL/hm2 had good control effects on gray mold of cucumber and leaf mold of tomato,the protection lasted for 21 d,and the best control effects were 90.7%and 80.3%,respectively.At the same time,it was found that the control effects of resveratrol 0.2%SL were related to the concentration,but there were no significant differences between the two dosages of resveratrol 0.2%SL 1 500 mL/hm2 and 1 800 mL/hm2.
