Remove any infected leaves, and treat your plants with a fungicide or pesticide to prevent the problem from spreading.

Extreme Temperatures

Tomato plants are sensitive to extreme temperatures. If it is too hot or too cold outside, the leaves can curl up as a result. Make sure your plants are planted in an area that receives enough sunlight, but is not too hot. If the temperature drops too low, bring your plants indoors or cover them with a cloth or plastic to protect them from the cold.
