Major virus diseases of fruit in Malaysia

Yaakob Doon, . (1993) Major virus diseases of fruit in Malaysia. [Proceedings Paper]

Important virus diseases affecting four major perennial tropical fruits namely citrus passion fruit papaya and banana are discussed with respect to occurrence disease severity symptoms and control measures. Citrus tristeza virus is the most important of all viruses affecting citrus worldwide. This virus is endemic to Malaysia. The symptoms induced vary with citrus species. Effective control measures include selecting budwood lines that carry mild virus strains and use of resistant rootstocks. Passion fruit mosaic virus disease is endemic in Peninsular Malaysia and it is the only major disease affecting the golden passion fruit passiflora edulis f. flavicarpa. The symptoms induced in passion fruit: include mosaic mottling and curling of leaves varieties developed through breeding. Papaya ringspot virus disease PRVD is a very serious disease affecting papaya worldwide. This disease presumably recently introduced was first detected in June 1991 in Johor Bahru. The symptoms observed in cultivar Eksotika were: yellowing and stunting of infected plants; water soaked streaks on petioles and stems; and ringspots on the fruit. Growing tolerant varieties and use of cross-protection by mild virus strains were practiced to control the virus. Banana bunchy top virus disease is one of the most important diseases of banana worldwide. The disease has not been detected in Malaysia. The disase caused stunting of affected plants followed by severe yield reduction. Control measures include control of the aphid vector and roguing of infected plants

Abstract

Important virus diseases affecting four major perennial tropical fruits namely citrus passion fruit papaya and banana are discussed with respect to occurrence disease severity symptoms and control measures. Citrus tristeza virus is the most important of all viruses affecting citrus worldwide. This virus is endemic to Malaysia. The symptoms induced vary with citrus species. Effective control measures include selecting budwood lines that carry mild virus strains and use of resistant rootstocks. Passion fruit mosaic virus disease is endemic in Peninsular Malaysia and it is the only major disease affecting the golden passion fruit passiflora edulis f. flavicarpa. The symptoms induced in passion fruit: include mosaic mottling and curling of leaves varieties developed through breeding. Papaya ringspot virus disease PRVD is a very serious disease affecting papaya worldwide. This disease presumably recently introduced was first detected in June 1991 in Johor Bahru. The symptoms observed in cultivar Eksotika were: yellowing and stunting of infected plants; water soaked streaks on petioles and stems; and ringspots on the fruit. Growing tolerant varieties and use of cross-protection by mild virus strains were practiced to control the virus. Banana bunchy top virus disease is one of the most important diseases of banana worldwide. The disease has not been detected in Malaysia. The disase caused stunting of affected plants followed by severe yield reduction. Control measures include control of the aphid vector and roguing of infected plants
