Older plants have soft lesions on stems, petioles, leaves or pods. White mat-like mycelium develops in older, rotted tissues. Plant in well-drained soils not recently used for beans, potatoes, tomatoes, lettuce or cabbage. For snap beans only. Apply fungicide 25 percent to 50 percent bloom and repeat at peak bloom.
Symptoms vary with virus and varieties.
Leaves are mottled and puckered with irregular light and dark green areas. Leaves may be narrow and strap-like. May have chlorotic spots like halos. Use certified seed of resistant varieties, such as Tender green, Top crop, Tender crop or Tenderette.
