Controlling Fusarium oxysporum Tomato Fruit Rot under Tropical Condition Using Both Chitosan and Vanillin

Tomato Lycopersicon esculentum Mill. is one of the most cultivated and widely consumed vegetables in world. However, it very susceptible to infection initiated by Fusariumoxysporum fruit rot, which shortens post-harvest life thus reduces market value. This disease can be regulated appropriately application synthetic fungicides. chemical fungicides constitute a serious health risk, have harmful environment effects increase resistance, even when microbes are dead. Hence, overcome this problem, chitosan vanillin, antimicrobial bioactive properties against growth microorganisms, could an alternative control, while maintaining quality prolonging shelf life. The aim research was evaluate activity vanillin towards inoculate pathogen investigate effect coating vivo on Fusarium oxysporum rot defense-related enzymes (PAL, PPO POD). Chitosan aqueous solutions, i.e., 0.5% + 10 mM 1% 1.5% 15 were used as edible coatings tomatoes stored at 26 ± 2 °C 60 5 relative humidity. result revealed able control incidence 70.84% severity 70%. These combinations also retain phenylalanine ammonia-lyase (PAL), peroxidase (POD), polyphenol oxidase (PPO) enzyme activities well prolong up days.
