Abstract

Nine plant growth regulators (PGRs) were tested for in vivo antifungal activities against on rice blast. They showed higher in vivo antifungal activities when they were applied on rice plants by soil drench rather than foliar spray. Except for 2,4-D at $500\;{\mu}g\;mL^{-1}$, the others showed a very low or no activity against the disease in foliar spray applications. In contrast, 2,4-D, indole butyric acid (IBA) and triiodobenzoic acid, at $500\;{\mu}g\;mL^{-1}$, showed control values of 98.9, 97.8 and 88.9% in soil drench applications. Furthermore, the control activity of IBA was dependent on its concentration against rice blast; IBA suppressed the development of rice blast by 71.7% at $125\;{\mu}g\;mL^{-1}$ and 85.8% at $250\;{\mu}g\;mL^{-1}$. IBA also controlled the development of rice blast on adult plants by 63.9% at a dosage of 2.56 kg/10a. The results revealed that IBA has a good activity against rice blast when it is applied by soil drench.
