How to Use Oil in Corn Silks for Worms


Corn earworm is one of the most prolific pests that corn growers must contend with to achieve a healthy harvest. The worms are actually moth larvae and feed on the silk and kernels of immature corn. Apply a mixture of mineral oil and bacillus thuringiensis, commonly called Bt, a natural bacteria that acts as an insecticide, to kill the larvae when your crop is still young and prevent them from wreaking havoc on your corn crop.

Things You'll Need

  • Mineral oil
  • Bacillus thuringiensis
  • Oil can
  • Mix the mineral oil and bacillus thuringiensis in a ratio of one part bacillus thuringiensis to 20 parts mineral oil.

  • Pour the mixture into an oil can.

  • Apply about five drops, or 1/4 teaspoon, to the silk at the top of each ear of corn six days after you first see silk on the ear.

Tips & Warnings

  • Mineral oil alone is an effective treatment if bacillus thuringiensis is unavailable.
