Abstract


Blast disease, caused by Magnaporthe oryzae, is one of the major constraints in the cultivation of the Inpari 64 rice variety. This study aimed to evaluate the effectiveness of Tiadinil 30SC as a plant activator in preventing blast disease, as well as its effects on rice growth and yield. The study was conducted from April to September 2025 using a randomized block design with four treatments: Tiadinil 30SC at concentrations of 20, 40, and 80 ml/L, and a control treatment, each with three replicates. The parameters observed included phytotoxicity, the percentage and intensity of blast infection, growth, and yield components. Data were analyzed using the F-test, followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that the application of Tiadinil 30SC did not cause phytotoxicity symptoms and was effective in reducing the percentage and intensity of blast infection. Concentrations of 40 ml/L and 80 ml/L provided the best disease control, while the application of Tiadinil increased the number of panicles, panicle length, number of grains per panicle, and dry grain weight at harvest compared to the control. Regression analysis indicated an optimal concentration of 51.25 ml/L, which is close to the 40 ml/L treatment. Therefore, a concentration of 40 ml/L is recommended as an efficient dose to support blast disease control and increase rice yields.
