Double action plant growth promotion microorganisms in suppressing Fusarium wilt disease and increase tomato production

Abstract

Fusarium oxysporum f.sp lycopersici is a fungus that causes wilt disease in tomatoes, attacking nurseries to mature plants. This study aims to examine several plant growth-promoting microorganisms (PGPM) to control Fusarium wilt and increase tomato production. The study was designed with a completely randomized design in a screen house with four treatments and three experimental units. The treatments tested were mycorrhiza 5 g per plant (M), a mixed solution containing Bacillus sp., Pseudomonas sp., and Trichoderma sp. 10 ml per plant (PGPM1), and combination treatment M and PGPM1 (PGPM2). The study showed a more extended incubation period of the pathogen-causing diseased plants with the treatment of PGPM2 compared to other treatments. The lower intensity of wilt disease was also found in the PGPM2 treatment. Consistently the same treatment also had a better effect on the number of leaves, plant height, and fresh tomato fruit production than other treatments. This study showed a significant effect of PGPM in controlling Fusarium wilt and increasing tomato production.
