Review of Technical Report Summary Photolysisof FM 3422 on Soil The report lacks any description of the experiments. The Materials and Methods section is missing. The fact that FM 3422 is virtually absent in the control soil is worrisome. Of course, an exact description of the control isn't given, but I assume it is the same coated soil not wexhpoolseesdtutdoy.sunTlhieghst.tudAy tshaonuyldbraetreet-hdeesciognntreodl inlocooknssuilntvaatliiodn, wwihtihachphesosteoncthiaelmliystinavnadlirdeapteeastetdh.e
