When diluted, PERpose Plus may be used in combination with most soluble fertilizers; test for physical compatibility and for phytotoxicity on a small portion of the crop before using on the entire crop. PERpose Plus is NOT compatible with products containing copper, magnesium/zinc, magnesium/copper, and aluminum, and may react with residues of recent foliar applications of metal-based fungicides or supplements. It may be used with most foaming and wetting agents.

Make applications of tank mix solutions as soon as possible after mixing; do not store overnight.
