If it is labeled for Nematodes, I have tried it. Of all the products currently on the market except Curfew, we have had the best success with MultiGuard Protect. We did several trials last year with it and pulled samples from 5 different greens prior to and following each monthly application. After each application our Sting counts cut in half. One green was as high as 240/10cc, or 24x the threshold limit. First application reduced to roughly 120, second to 60, etc....After the third application we went ahead with out pre-planned Curfew application. We then continued the program as we moved into the fall with three sequential applications. Although we maxed out the amount of product we could apply, we were happy with the results. We have already made one application this spring at the high rate, and will follow it up with app #2 next week.
We have also had good success with Nortica. However, I personally feel that you need to knock down the existing application for this product to be effective. This is achieved by either applying Curfew or applying Nortica in the fall prior to cool weather that would naturally slow the Nematodes down. We have also applied applications of Nortica this year.
