Per Requester: Very Good Fit; Foliar applications of potassium phosphite have potential to be part of an integrated program for control of both Pythium pod rot and early and late leaf spot diseases of peanut. Their use would complement genetic and cultural practices used for leaf spot management, and would provide one of the few options for control of Pythium pod rot:06/25;

| Reasons for need: |
Pythium pod rot of peanut (Pythium myriotylum); early leaf spot (Passalora arachidicola); late leaf spot (Nothopassalora personata). The target diseases are Pythium pod rot and certain foliar diseases (phosphite in combination with other registered products). Pythium pod rot is and important disease in most of the peanut production areas of the United States. Phosphites are the only products useful against Pythium when applied by means other than irrigation systems. This is a request for the continuation of a recent IR-4 Project, PR#12705. There is a need to address MRL issues in the EU for phosphorous acid (phosphites) fungicides. The original project consisted of 6 residue studies, however the EU has changed residue test requirements and now require 8 trials (EUROPEAN COMMISSION HEALTH & FOOD SAFETY DIRECTORATE-GENERAL This request is asking for only 2 additional residue studies to satisfy the new EU requirement:06/25;
