Re: SVB thinkings
John and all. Several years ago I did some experimenting with injecting
Bt into the vines with a syringe. I tested this on acorn squash but now
use it on the pumpkin vines when a see a hole with sawdust. Mix about a
teaspoon of Bt into a pint of water. I sometimes add a little Malathion
also if using only on pumpkins. I inject into the vine at about 12"
intervals, directly into the hollow center,then repeat in about 3 days.
This does not harm the plant and will kill the borers. Bt will cause an
insect to stop eating immediately, but it takes a few days until it is
dead. Bt is not toxic to humans and is used by the state forestry dept.
to kill Gypsy moth caterpillars.
Vine borers seem worse than usual here in PA this year.
