Tomato fruits may crack open or cat face. Avoid using 2, 4-D near the garden area or spraying on windy days. Always use a different sprayer for fungicides and insecticides than on the one used for weed killers. This occurs when tomato plants are pruned severely. It is also common when heavy rains maintain an excessive amount of moisture in the soil for a prolonged period.
Plants show upward rolling of leaflets of the older leaves.
