Abstract
The inhibitory activity of Tebuconzole , Fluazinam, Fludioxonil, Cartap, and their mixtures to the hyphal growth of Fusarium verticillioides Nirenberg, and their nematicidal activity to Aphelenchoides besseyi were tested in laboratory by using mycelial growth rate method and dipping method , respectively, and the co-toxicity coefficient (CTC) of their mixtures was determined by u-sing Sunyunpei's method.The results showed that the EC50 values of Tebuconzole, Fluazinam, Fludioxonil and Cartap against the hyphal growth of F.verticillioides were 0.3097, 0.3342, 1.0068 and 2077.27 μg/mL respectively, and their LD50 values against A.besseyi were more than 2000, more than 2000, above 2000, and 22.1177μg/mL respectively.Both the mixture of Tebuconzole+Fluazinam +Cartap (1∶2∶2) and the mixture of Tebuconzole +Fludioxonil +Cartap (1∶2∶2) had the best inhibitory effi-ciency on the hyphal growth of F.verticillioides and the best nematicidal efficiency on A.besseyi.In the field test, using the 1000-fold solution of 12.5%Tebuconzole· Fluazinam· Cartap (1∶2∶2) WP or the 1200-fold solution of 12.5%Tebuconzole· Fludi-oxonil· Cartap (1∶2∶2) WP to soak rice seeds for 48 hours had better control efficiency on bakanae disease of rice , and these two kinds of seed-soaking agents were safe to the seed germination and seedling formation of rice .关键词
