White Peas

Mark VanGessel, Extension Weed Specialist; mjv@udel.edu

There are a number of fields in the area with white peas due to carryover or residue of Callisto in the tank. Peas are very sensitive to Callisto and, as many are now aware, carryover is a concern. If Lumax, Lexar, Halex, or Callisto has been used this year, be sure the tank is cleaned out well before spraying peas (or any other vegetables) with a postemergence herbicide. Syngenta recommends using ammonia (at 1 gallon per 25 gallons of water) or a commercial tank cleaner. In addition, do not use any of the above products on fields where you are considering growing peas next year.
