I sprayed 3.5 oz of generic Valor with LV6 late this fall on a cornstalks that had a lot of waterhemp escapes. Going to No-Till E3 soybeans next year. Typically have been using 6oz of gen. Sonic, 4oz of Metribuzin, and Glyphosate following the planter. Used my group 14 this fall so I'd better not use the Authority in Sonic. Should I assume most of the Valor will still be active in the spring? We've had snow cover for a month already. Most of the Zidua premixes also have a group 14 in them. Should I go with a group 15 - plain Zidua? Dual? Acetachlor? or Prowl? Have had some problems with not getting enough rain after planting and spraying to get the pre's activated-part of the reason for fall spraying. Will post with Gly, Enlist, and Liberty
