Effect of Aqueous Neem Leaf Extracts in Controlling Fusarium Wilt, Soil Physicochemical Properties and Growth Performance of Banana (Musa spp.)

Neem leaf extracts (NLEs) have frequently been used to inhibit plant diseases and for the development of bio-fertilizer, leading commercial exploitation this tree. However, previous studies indicated contradictory outcomes when NLE was as an antifungal disease treatment bio-fertilizer applied through soil on several crops, including banana. Therefore, present investigation undertaken examine physicochemical properties soil, growth performance severity caused by Fusarium oxysporum (Foc) Cavendish bananas treated with aqueous NLE. Banana plants associated fungus were significantly affected high symptoms index (external leaves internal rhizome), a infection percentage wilt (%), dropping off well rotting root. Meanwhile, it observed that application extract improved crop height, stem diameter, root size distribution (root surface area, volume), root–shoot ratio, (CEC, N, p, K, Ca, Mg), which enhanced resistance diseases. We conclude solution promotes better banana plants, properties, infection.
