Banana (Musa spp.)
Banana streak disease (Banana Streak Badna Virus)
Symptoms
- The virus is transmitted mostly through infected planting materials by mealy bugs (Planococcus citri; Saccharicoccus sacchari).
- Yellow streaking running parallel to the leaf and perpendicular to the leaf veins on the leaves, which becomes progressively necrotic producing a black streaked appearance in older leaves.
- Chlorotic to dark green streaks also appear on the midrib, petiole and pseudostem.
- Leaf gets reduced in size, becomes brittle and rolls upward with mosaic mottling.
Management
- Systematic eradication of the diseased plants, suckers and the clumps is very essential.
- Planting materials should not be collected from places affected by this disease.
- The mealy bugs/aphid should be controlled
- Avoid growing leguminous and cucurbitaceous vegetables as intercrop.
- Before planting, spread lemon grass in the pits.
