Abstract: Peanut plants are susceptible to major fungal diseases, which significantly affect yield. This study evaluated the effects of Piper betle leaf extract on leaf spot (Cercospora sp.), rust (Puccinia arachidis), and stem rot (Sclerotium rolfsii) occurrence on peanut. The experiment was laid out in a Randomized Complete Block Design (RCBD) with seven treatments replicated three times. The treatments were: T1 - Negative Control: Water, T2 - Positive Control: Ridomil Gold, T3 - 1 ml Piper betle Leaf Extract/L of Water, T4 - 2 ml Piper betle Leaf Extract/L of Water, T5 - 3 ml Piper betle Leaf Extract /L of Water. T6 - 4 ml Piper betle Leaf Extract /L of Water, and T7 - 5 ml Piper betle Leaf Extract /L of Water. Results revealed that the 5 ml Piper betle leaf extract per liter of water significantly reduced leaf spot and rust severity, though it was still less effective than the commercial fungicide. However, this extract had no significant effect on stem rot incidence. The study highlights the promising antifungal properties of Piper betle leaf extract as a natural alternative for disease management in peanut production.
