Twice over the last 10 years, a producing zuchinni plant has suddenly
died. I suspect some type of borer but am not sure. I have read many
posts concerning injection Bt into the stems. My question, can this
method be used as a pro-active strategy? Also, I have never attempted
this solution and would like all the help I can get? What is Bt, how
do I mix it, how much do I use, where do I inject the plant and how
often?
