Be sure you are watering deeply through the root zone because tomatoes are very moisture sensitive and foliage can curl if drought stressed. However, it might be curly top virus, which infects many vegetables, including tomatoes. It is transmitted by the beet leafhopper. Unfortunately, there is no cure once it's infected plants. Infected plants should be eliminated since they will not recover, but transmission of the virus from plant to plant is dependent on the leaf hopper only. Once the leafhoppers have left, new infections will not occur. In small gardens, disease may be reduced by shading plants during early growth since the leafhoppers prefer to feed in sunny locations. Sequential plantings also can be effective since there is a better chance plants become established in absence of leafhopper migrations.
