Needing help with corn borers

brarizonaAugust 13, 2012


I'm trying to raise a batch of sweet corn in a 4x4 raised bed in the desert of Tucson, AZ. It was going beautifully. Tassels sprouted, silks emerged, saw a few ladybugs working on the aphids. Now, I have seen a couple little worm/caterpillar-looking varmits. They are drilling holes in my perfect little baby corns! They disgust me! I have been going out twice a day to search for them and I have practically covered the plants with diatomacious earth. Is there anything else you guys can recommend?

In the ears of the corn or the upper stalks that would probably be the Corn Earworm rather then the Corn Borer which usually is a root eater.
If in the corn ears a few drops of mineral oil can help, Bacillus thuringiensis or Spinosad if applied in the earluy life stages can help keep them from the ears. Pyrethrin based dusts might be a last resort.
