Shallot is a horticultural plant that is susceptible to pathogen attacks. The continuous use of non-biological fungicides has a negative impact on the environment, making it necessary to implement biological control using antagonistic microorganisms. This study aims to evaluate the differences in growth and yield of shallots treated with a dry formulation of Trichoderma sp. to control Fusarium wilt. The study was conducted using a Randomized Block Design (RBD) with four treatments and six replications. The concentrations used were 0 grams/liter, 7 grams/liter, 14 grams/liter, and 21 grams/liter. The data analysis results showed that the dry formulation of Trichoderma sp. at a concentration of 21 grams/liter was the most effective in controlling Fusarium wilt, with the lowest disease severity of 23.16 (F_1,24=47.61, p<0.05). It also significantly increased plant height (F_1,24=6.36, 7.89, 14.24, p<0.05), the number of leaves (F_1,24=15.62, 16.07, 18.29, p<0.05), the number of bulbs (F_1,24=13.57, p<0.05), and biomass weight (F_1,24=57.34, p<0.05). The higher the concentration of the dry formulation of Trichoderma sp. applied, the greater the increase in the vegetative and generative growth of shallot plants.Downloads
