Arbuscular Vascular Mycorrhizes (MVA) to Control Wilt Disease in Tomato (Solanum lycopersicum L.)

Background: Pests and diseases can cause suboptimal tomato production. One alternative that can be used to control wilt disease in tomato plants is to use biological agents. Biological agents that have the potential to control wilt disease in tomato plants are mycorrhizae. This study aimed to determine whether mycorrhizal treatment was effective in the growth of tomato plants and the control of wilt. Methods: The research design was a randomized block design (RBD) arranged factorially. This study used two factors and the first was the dose of mycorrhizal application (M) with three treatments consisting of M1 = mycorrhizal 25 spores/plant, M2 = mycorrhizal 50 spores/plant and M3 = mycorrhizal 75 spores/plant. The second factor was Mycorrhiza (T) application time using two treatments consisting of T1 = when the tomato seeds were sown and T2 = when transplanting. All treatment combinations were repeated 4 times. The varieties used are varieties that farmers usually plant, namely the F1-resistant variety, which was an introduced hybrid plant. The type of plant was a determinate plant. Result: The results showed that the mycorrhizal treatment with 75 spores significantly increased tomato plant growth on parameters such as plant height, number of leaves, fruit weight and reduced disease incidence.
