Borer is a white larva with brown head, up to 1" long. Preferred foods: pumpkin, squash, cantaloupe, cucumber and gourd vines. A small pile of "sawdust" where the vine meets the soil is a sure sign you have the borers. Once you notice "sawdust," it will not be long before the leaves wilt and the vine dies. Standard procedure is to slit the base of the vine with a razor blade and try to extract the borer larvae, but expect reduced vine size and productivity.
When vines start to run, spray spinosad weekly five or six times. We recommend Bull's-Eye™ Bioinsecticide. If borers have already entered the vine, instead of slitting the vine, inject Nema-Ject™ Nematodes at 4-inch intervals over the first 3 ft. of vine. Adult moths lay eggs from late June to early August; covering with a Super- Light Insect Barrier during this time will significantly reduce borer damage. (Pull back cover to allow for pollination.)
