verticillium battle
We've had our hoop house plants diagnosed and the soil contains verticillium. Last year we did experiments in it using Actinovate and Terraclean as soil drenches in different beds. We would like to do the same type of experiments this year but now I'm wondering..... Will the drenches from last year still be in the soil? It won't help us doing the experiment if the soil is already altered from last years drenches. Does the stuff have a lasting effect or does it dissipate or break down in the winter? Anyone know about long term use of either product?
