follow up on Mustards used as soil fumigants

Karl is the plant pathologist for our part of Texas. This is his follow up reply about the effects of using mustards for a winter crop and then tilling them into the soil for spring. As usual if we actually wanted tests done with daffodils then we would have to do this as a group on our own fields. It looks like 30 days after tilling in the mustard it is safe to replant some of the crops. Keith Kridler Mt. Pleasant, Texas
