TOBACCO MOSAIC VIRUS (TMV)

Symptoms: Plants show mosaic and systemic chlorosis and leaf drop.

Control: TMV is spread mechanically, by hands touching an infected plant and then an uninfected plant. Plant clean seed, use crop rotation, and wash hands and equipment after handling infected plants.

TOMATO SPOTTED WILT VIRUS (TSWV)

Symptoms: Young pepper plants are stunted and exhibit yellowing and/or necrotic spots on the leaves and terminal shoot. Leaves infected later may show chlorotic line patterns or mosaic with necrotic spots. Fruit of infected plants has chlorotic spots, streaks, mosaic, and ring patterns. On ripe fruit, yellow spots with concentric rings or necrotic streaks may be present.

Control: TSWV is carried by thrips that feed on various virus-infected perennial flowering plants commonly grown around homes. Use clean seed and control thrips.
