In one sentence, describe what the following article is about: Plain mineral oil is a very effective insecticide. Apply 0.75 to 1 milliliter (0.025 to 0.034floz) directly to the corn silk by pouring or spraying, five to seven days after the silk appears. Since this is a fairly laborious process, it is best for home gardeners growing a small amount of corn. Some varieties of bacteria, such as Bacillus thuringiensis, suppress corn earworms. Check with your county extension office to see if these are approved in your area. Steinernematidae and entomopathogenic nematodes can also help reduce corn earworm populations when they are added to the soil your plants grow in. However, these work by killing larvae when they drop to the ground to pupate, which means there will probably still be some damage to your crop. Look for nematodes at a crop supply store. A number of insects will feed on corn earworms, including lacewings, pirate bugs, damsel bugs, ladybirds, and big-eyed bugs. Some of these may naturally be attracted to your crop, while others are available from farm supply stores and can be artificially introduced. Field birds will also feed on the corn earworm larvae, though there are rarely enough of them around to adequately control the pest. Still, consider not driving birds from your fields for a little extra protection against corn earworms.
Summary: Apply mineral oil to the corn silk. Apply bacterial controls. Introduce nematodes to the soil. Encourage natural predators.
