Abstract
The authors conducted a survey of Pineapple Mealybug Wilt-associated Virus (PMWaV) on pineapple plants in four pineapple-producing sub-districts in North Tapanuli, namely Sipahutar, Pangaribuan, Siborongborong, and Tarutung. This survey aims to detect the presence and distribution of PMWaV in North Tapanuli. The survey found PMWaV in pineapple plants in all survey locations with varying symptoms such as wilting to a yellow-red colour and curling leaf tips, curling and drying leaves and leaf tips, and showing symptoms of wilting to a redand yellow colour. The results showed an incidence rate between 15.6 to 80%. Sampang ni Huta V, Sipahutar, showed the lowest incidence rate (15.6%), while Lobu Siregar, Siborongborong, showed the highest (80.0%). Meanwhile, the severity rate was between 14.0 and 65.0%. Pancur Natolu, Pangaribuan, showed the highest severity rate (65.0%, severe), while Siabal-abal II, Sipahutar, showed the lowest (14.0%, moderate).
