by W.T. Thomson, page 220 now quoted in reference to using coumaphos "Do not
use before or after application of natural or synthetic pyrethrins or
compounds used to synergize them."

now going to switch to coumaphos, has this warning under coumaphos not to
use with pyrethrins been checked out? Does Germany, where coumaphos is used,
also use fluvalinate safely or hasn't it been checked out either?
