This research was aimed to examine the influence of neem-wood vinegar on inhibiting fungal growth of banana ‘Namwa Mali-ong’ ropes produced in Chai Badan district, Lopburi province. The experiment was conducted using banana rope samples prepared by four methods: Rope_A (control sample), Rope_B (bleached with sodium hypochlorite), Rope_AN (treated with neem-wood vinegar), and Rope_BN (bleached with sodium hypochlorite and treated with neem-wood vinegar). The results showed the growth of white mycelium fungi in the Rope_A sample only. Sodium hypochlorite and neem wood vinegar solutions could inhibit the growth of the white mycelium fungi. After 30 days of storage at natural condition, 3 mycelium fungi (white, black and green mycelium fungi) were found in Rope_A30 sample (Rope_A after 30 days of storage at natural condition). While Rope_B30, Rope_AN30, and Rope_BN30 samples (banana ropes bleached with sodium hypochlorite and/or treated with neem-wood vinegar after 30 days of storage at natural condition) showed only black mycelium fungi and their numbers were less than in the Rope_A30 sample. This research indicated that sodium hypochlorite and neem wood vinegar could inhibit and reduce fungal growth during product storage but decrease the tensile strength of banana rope products. Neem wood vinegar affected strength reduction less than sodium hypochlorite but increased darkness in banana rope color.
