摘要
采用室内生物活性测定及田间药效试验,以40%嘧霉胺悬浮剂为对照药剂,评价了生物杀菌剂枯草芽孢杆菌可湿性粉剂(活芽孢数为1 000亿.g-1)对黄瓜灰霉病的防治效果。试验结果显示,枯草芽孢杆菌可湿性粉剂对黄瓜灰霉病的抑制效果较好,与对照药剂相当,其EC50为5.89×106cfu.mL-1。田间试验中枯草芽孢杆菌可湿性粉剂0.08 g.m-2施药后的防效为70.81%,对照药剂0.11 g.m-2的防效为77.40%。室内生物活性测定结果与田间试验结果一致。
The antifungal effect of 1 ×10^11 cfu·g^-1 Bacillus Subtilis WP against cucumber gray mold （Botrytis cinerea） tested by allied toxicity measurement and feld efficacy trials. The result showed that Bacillus Subtilis WP had good inhibitory effect on cucumber gray mold （Botrytis cinerea） with EC50 of 5.89 × 10^6 cfu·mL^-1, which indicated that it had the same effect with control insecticides Pyrimethanil. The same result was found in field experiment. The efficacies of 0.08 g · m^-2 Bacillus Subtilis and 0. 11 g · m^-2 control insecticides were 70.81% and 77.40 % respectively.
