To control bacterial spot and anthracnose
rotate crops, avoiding land growing potatoes,
tomatoes, or eggplant the previous year, and do
not grow next to other solanaceous crops. To
avoid sunscald, keep fruits shaded; spray to con-
trol leaf spots to prevent defoliation. For virus
diseases, obtain healthy seed or use resistant vari-
eties. Do not start plants in greenhouses with
petunias or Jerusalem cherries; do not smoke or
handle tobacco near plants; control aphid vectors;
control weed hosts before the crop is planted.
