Squash vine borers
"enigma" wrote in message .. . "Katey Didd" wrote in : The vine borers here get into the main stem and kill the plant, not the seedlings. They usually start their damage when the fruits have already started to form. I've yet to ever see the adults. I've tried to slit the vines to remove them and the plants would die anyway. They're not easy to find in the vines and slitting the vines seems to kill the plants even faster. Have you tried tinfoil collars and did the work for you? the adult is a clearwing moth. i've never had borers kill mature vines, but i bury vines as they grow so that they root along the length. i do put tinfoil collars on young plants of the squash & cucumber family. if borers are a real problem, you could try floating row covers & hand pollenate the flowers... We're retired now and can't afford to by row covers. This gardening is starting to get expensive. Insecticide, weed cloth, fertilizers, limestone, Ironite......... are you slitting the vines where the borers are, or are you slitting the entire vine looking for them? there's usually a hole with frass near the borers location, & the moth lays the eggs at the base of the vine, so the first place to look is at the base, & then look for the frass. The *&^%$# borer is usually not near the hole. I have to slit the stem and look for it, and the plant (crooknecks and zucchini) never recovers. I'm going to put collars on them and use Sevin under and around the collars. If that doesn't work I'll have to give up on these squash. lee -- Last night while sitting in my chair I pinged a host that wasn't there It wasn't there again today The host resolved to NSA. |
