2024 Pea Herbicide Chart
Julie Kikkert, Team Leader, Extension Vegetable Specialist
Cornell Vegetable Program
It is important to select the proper herbicides for a particular crop. To be most effective, the herbicide must be applied at the correct stage of crop development and weed size. The Relative Effectiveness of Herbicides Available for Use in Peas, 2024 chart gives details on rates, pre-harvest interval (PHI), and weed species controlled. However, it is critical to read the product label thoroughly.
Post-Emergence herbicides have very specific language as to which stage of the pea crop it can be applied to. Click on the Pea Growth Stage file for help with counting nodes in peas.
