Abstract

Downy mildew caused by Peronosclerospora spp. is a major limiting factor in maize production in Indonesia. Susceptible variety can have yield losses of around 90 to 100%. The use of metalaxyl fungicide continuously was triggered resistance to downy mildew pathogens. Therefore, it is necessary to have other fungicides that can replace the use of metalaxyl. In this study, the oxathiapiproline-famoxadone fungicide will be tested in combination with the fungus Trichoderma sp. as an alternative to metalaxyl. This study used a Randomized Complete Block Design (RCBD). The treatments were arranged in factorial with 2 factors. The first factor was fungicide (without/F0 and with fungicide/F1). The second factor was Trichoderma sp., i.e.: T0 (Without Trichoderma sp), T1 (Trichoderma sp. 106 spores/ml), T2 (Trichoderma sp. 107 spores/ ml), and T3 (Trichoderma sp. 108 spores/ml). The results showed that the oxathiapiproline-famoxadone fungicides were able to suppress downy mildew, while the application of Trichoderma sp. did not affect the control of downy mildew and maize plant growth. Fungicide treatment and Trichoderma sp. 107 spores/ml suppressed disease severity at 7 days after inoculation with Peronosclerospora sp. Keywords: Corn, Disease, Induced resistant, Pathogen
