2-氰基丙烯酸酯类新化合物杀菌活性筛选研究

Bioassay Screening for Novel 2-Cyanoacrylate Compounds to Three Pathogens

继2-氰基丙烯酸酯类杀菌剂氰烯菌酯(JS399-19)研发后,又发现该类化合物对小麦白粉病、小麦纹枯病具有高活性。新化合物JS399E12对小麦白粉病EC50值为1.3397mg/L,新化合物JS399F05在50mg/L的剂量下对小麦纹枯病的防效达90%以上。实验室条件下,JS399-19对小麦赤霉病高效,但对小麦白粉病和小麦纹枯病无效。本研究为该类化合物的研发提供了参考。

The high fungicidal activity of 2-cyanoacrylate compounds against the wheat powdery mildew（Blumeria graminis） and the wheat sharp eye spot（Rhizoctorua solani） has been discovered after research and development of 2-cyano-3-amino-3-phenylacylic acetate（JS 399-19）.The experiments showed that a new compound,JS 399E12,had excellent fungicidal activity to wheat powdery mildew.It s EC50 was 1.339 7 mg/L.And another new compound,JS 399F05,had good activity to wheat sharp eye spot.It s control effect was over 90 pe...
