摘要
采用番茄灰霉病防治中6种已登记杀菌剂和7种未登记杀菌剂对番茄灰霉病菌进行室内毒力测定,并通过EC50和病原菌的抗性水平进行抑菌效果对比。结果表明:在已登记的6种杀菌剂中,以25%啶菌恶唑EC的抑菌效果最好,EC50值为0.14 mg.L-1番茄灰霉病菌对其表现敏感;在未登记的5种杀菌剂(包括10%多抗霉素B)中,25%咪鲜胺EC的抑菌效果最好,EC50值为0.66 mg.L-1番茄灰霉病菌对其表现敏感;在2种未登记活体微生物杀菌剂中,抑菌效果最好的为2×108cfu.g-1绿色木霉菌WP,EC50值为0.001×108cfu.L-1。
The fungitoxicity of six fungicides registered ih control of tomato gray mold and seven fungicides unregis- tered to Botrytis cinerea were determined. The result showed that 25% SYP-2048 EC had the highest inhibition rates in the six registered fungicides, of which the ECso value was 0. 14 mg· L-1 ; 25 % prochloraz EC had the highest inhi- bition rates in the five unregistered fungicides ( 10% polyoxin B included), of which the EC50 value was 0. 66 mg· L^-1. In microbial fungicides, the inhibition rate of Trichoderma viride WP (2 × 10^8 cfu· L^-1), of which the EC50 value was 0. 001 × 10^8 cfu· L^-1 , higher than Bacillus subtilis AS(8 × 109cfu·mL^-1 ).
