Abstract

Fusarium wilt disease is a growing concern in cucurbit crops in the Philippines. Most often than not, farmers highly depend on commercial fungicides for control but these chemicals are very expensive and not environment-friendly. Biofumigation and green manuring using Brassica plants is a potential alternative for sustainable management of this destructive disease. A study was conducted to evaluate the efficacy of mustard var. Montevede as a biofumigant and green manure to control Fusarium wilt disease of bittergourd (Momordica charantia L.) and bottlegourd (Lagenaria siceraria (Mol.) Standl.). In vitro assay of mustard slurry resulted in 100% suppression of the mycelial growth of F. oxysporum f. sp. momordicae and F. oxysporum f. sp. lagenariae isolates after exposure to 5, 10 and 15 g of mustard slurry compared with the control. Similarly, incorporation of the macerated mustard leaves in the infested soil reduced Fusarium wilt incidence by 100% in bittergourd and bottlegourd. The effect of mustard was comparable to Bavistin® fungicide both in vitro and in vivo. © 2013 Copyright Taylor and Francis Group, LLC.
