Abstract

Fusarium wilt disease caused by pathogenic fungus F. oxysporum f. sp. cubense is an important disease in banana plants. This research was aimed to identifiy Fusarium spp. collected from banana plants showing wilt disease based on morphology and molecular characters.  The fungi isolates obtained was further examined for its pathogenicity and distribution in various parts of banana plants.  Based on morphological characters, i.e. growth rate, total conidia, colony color, macroconidium, microconidium, and chlamydospores, F. oxysporum f. sp. cubense can be differentiated from other species of Fusarium, but not the strain. Molecular analysis using specific primers VCG 01213/16 and Foc1/Foc 2 successfully identified 13 and 7 isolates of F. oxysporum f. sp. cubense TR4 and F. oxysporum f. sp. cubense non TR4, respectively.  Analysis using universal primer ITS4/ITS5 identified 7 isolates of F. solani, 1 isolate of F. verticillioides, and 2 isolates non Fusarium.  Infection of F. oxysporum f. sp. cubense TR4 and non-TR4 were found mostly in pseudo stems, whereas F. solani and F. verticillioides dominantly colonized banana corm. Pathogenicity test showed that F. oxysporum f. sp. cubense TR4 and non-TR4 caused necrosis on corm of cv. Ambon Kuning.  Similar necrosis symptom was also observed on infection of F. solani but with less severity.

Abstract

Effect of Various Yeasts Antagonists on Anthracnose Disease and the Shelf Life of MangoPostharvest decay on mango may occur due to physiological damage and/or postharvest disease especially anthracnose. This postharvest decay may decrease the quality of mango fruit. The use of antagonists yeast as biocontrol agent is an alternative control measure for postharvest diseases of fruits. This study aimed to screen yeast species as biological control agents and in the same time delaying the maturity of fruits to extend its shelf life.  Six isolates of yeasts were evaluated, namely Cryptococcus albidus, Cryptococcus terreus, Aureobasidium pullulans, Rhodotorula minuta, Candida tropicalis, Pseoudozyma hubeiensis); fungicides treatment using azoksistrobin was applied for comparative treatment. The study was conducted at two temperature conditions, namely room temperature and 15 ° C. It was evidenced that C. albidus, A. pullulans, and C. tropicalis were effective to control anthracnose disease on mango under both temperatures.  Furthermore, C. tropicalis and A. pullulans were able to extend manggo shelf life for 21 days at room temperature and for 54 days at 15 °C, respectively.
