In one of my posts last year you mentioned that you used the 2% disulfton (Hi-Yield). I think you mentioned a couple of teaspoons around each plant when you discovered the nematodes and then another application the next spring.
My question is do you continue to treat every year as a precaution, or was that application sufficient in your garden to take care of the little buggers?
I was going to use it last year, but was also concerned about toxicity. I wonder how long it stays in the plant's system.

As always, I appreciate the your advise, experience and the POTD. I've learned so much from you. Thanks!
