Apply at a rate of 1 cup per 100 feet of row. Keep peppers as weed-free as possible. Hoeing, cultivating, straw mulches and black plastic mulches can be used. Adequate irrigation will ensure good yields. They usually enter at the stem end.
Infested peppers have severe decay inside.
Damage is more likely to occur in July and early August. Because control is needed before the caterpillar enters the fruit, early detection is important. Sevin and perhaps Rotenone will provide control. They can be picked off or washed off fruit. On rare occasions Colorado potato beetle will also infest peppers, particularly if other preferred hosts like tomato or eggplant are not nearby.
