Answer :

A. Your tomato plants have been injured by 2,4-D or a similar weed killer. Never use the same sprayer for weed control in your vegetable garden you used on your lawn. Drift from herbicides originating onehalf mile or more away can also injure tomato plants. A virus disease called cucumber mosaic virus (CMV) can mimic these symptoms.
