Symptoms
Dark-green stripes, blotches or oak-leaf patterns along the veins of young leaves, with mild mottling and slight stunting. Seed from infected plants carries the virus into the next crop.
Prevention
Use certified virus-free seed and rogue out infected plants early, as the virus is seed- and aphid-transmitted. Control aphid vectors and avoid saving seed from infected fields.
Treatment
Organic
There is no cure; manage aphid vectors with neem oil and reflective mulch. Remove infected plants and never use their seed for replanting.
Chemical (last resort)
No chemical cures the virus. Suppress aphids with a systemic insecticide if pressure is high, but clean seed and roguing matter most — observe PHI.
