We have been especially concerned about the high cost of nematicides and the problems handling them. COMPANY X introduced a product to us about three years ago called PRODUCT X.
They suggested that we use it in place of nematicides, as a natural solution to the nematode problem.
We have been using PRODUCT X for the past three years on carrots and melons and are very pleased with the results.
We had as good or better crops without using any chemical nematicide. "
