Pineapple is one of Indonesia's commodity fruits with high economic value. Disease in pineapple plants is one of the factors that can affect productivity in pineapple plants, one of which is wilt disease caused by a virus (closterovirus) characterized by red leaves. The research was conducted from February 2023 to May 2023 in Bukit Merdeka Village, Samboja District. The research used descriptive methods with observations of PMWaV disease symptoms, cultivation techniques, PMWaP vectors and secondary pathogenic fungi. Sampling of disease intensity was done by purposive sampling, which is the withdrawal of samples based on predetermined criteria. Calculations were carried out on 4 pineapple fields with different plant ages. The parameters observed were disease intensity, presence and identification of vectors and secondary pathogenic fungi. The results showed that the intensity of PMWaV wilt disease on pineapple plants in Samboja District was 81.16% for land 1, 92.3% land 2, 79% land 3 and 73% on land 4. The age of pineapple plants on the land did not affect the intensity of PMWaV wilt disease attack. The vector of PMWaV is Dysmicoccus bravipes, secondary diseases in pineapple plants attacked by PMWaV disease are fungi Fusarium sp1, Fusarium sp2. and Curvularia sp.
