Corn and tomatoes- Call it a corn earworm, call it a tomato fruitworm--it's the same beast in either case and likes both crops equally. Keep some distance between the corn and tomato patches.

Insect-Repellant Plants All plant-eating bugs avoid members of the onion family--probably because they stink. The greater the distance any bug has to cross from one feast to the next, the more likely it will itself become prey. Cabbage butterflies that have to flit all over the garden in search of cole crops will get more predatory attention than butterflies that can settle in one bed. The striped Colorado Potato Beetle is a nightshade nightmare and will feed on any plant related to potatoes, such as tomatoes, peppers or eggplant.
