How do you prevent earworms in corn?
Growing season:
Spray or inject silks weekly with Beneficial Nematodes to control larvae. If corn earworms persist, apply Safer Garden Dust (Bacillus thuringiensis) or Monterey Garden Insect Spray (Spinosad) to silks at 5-10% formation and continue weekly until tassels turn brown.
How do you control corn earworms organically?
Many gardeners get good organic control of corn earworms by using eyedroppers or small squirt bottles to place a few drops of canola or olive oil in ear tips, as soon as the silks show signs of drying. You also can use a standard solution of Bt (Bacillus thuringiensis) or spinosad in the same way.
How do you control corn pests?
The best approach to managing insect pests in corn is preventive control. Baythroid® XL insecticide, a pyrethroid, performs on a broad spectrum of corn insect pests with fast knockdown and long residual control. At-planting application is recommended; however, Baythroid XL may be used throughout the growing season.
What can you spray on corn for worms?
A formulation of 1 part Btk or Neem with 20 parts oil is recommended. Apply 5 drops (0.5 ml) from an eyedropper directly to the top of each ear. Timing is critical. Spray when silks have reached their full length and began to wilt and turn brown (this is 5–6 days after 50% of the corn has begun to show silks).
How do you kill a corn?
Use of glyphosate is highly effective for non-Roundup Ready corn. But, the challenge is in removing Roundup Ready hybrids. There are limited herbicides to consistently kill small corn plants. Gramoxone SL, Liberty, and Select Max are three products that have shown the most activity.
Can I eat corn that has a worm in it?
Finding a corn earworm while shucking an ear of corn is a nasty surprise, but the corn itself is fine to eat. Just discard the worm and cut off the affected section of the ear before using it.
What will kill corn earworms?
Applying mineral oil to the silk where it inserts into the ear is an effective treatment to get rid of earworms. The oil suffocates the larvae. There are insecticidal sprays that are used for earworm control in corn, but great care should be taken in the use of these products.
What do you spray on corn?
You can spray corn plants with Bacilulus thuringiensis called BT. This insecticide contains bacteria that affect only the larvae of the corn borer. Your local garden center can provide you with all the information on approved insecticides.
How do you prevent earworms?

How do you get rid of a corn leaf aphid?
You can often get rid of aphids by wiping or spraying the leaves of the plant with a mild solution of water and a few drops of dish soap. Soapy water should be reapplied every 2-3 days for 2 weeks.
How do you control corn flea beetles?
Control of corn flea beetle is only needed until the 7-leaf stage. The most effective option is to purchase seed that has been treated with systemic insecticides (Gaucho, Cruiser, or Poncho). These insecticides are effective against corn flea beetles and the protection lasts until the 5th true leaf stage.
