2015 Lima Bean Herbicide Chart
Julie Kikkert, Team Leader, Extension Vegetable Specialist
Cornell Vegetable Program

Serious injury can be caused to lima beans if Eptam, Reflex, Assure II/Targa, or PostEmergence applications of Pursuit are used.
Herbicides that are labeled for lima beans in New York are given in the table below. Mark VanGessel from the University of Delaware provides the following information: on our loamy soils (approx. 1% organic matter) growers use 1.0 to 1.25 pints/A of Dual Magnum (rates similar for snap beans) and 1.5 to 2.0 oz of Pursuit at planting. They can be used pre-plant incorporated (PPI), but most farmers are applying them immediately after planting (PRE). Sandea is also labeled, but Pursuit is a better fit for the weeds in DE. Basagran, Sandea, Poast and Select Max are labeled for post-emergence control, with the choice depending on the weeds that emerge. We have a lot of Pursuit/Sandea resistant pigweeds in DE so be sure to rotate away from this mode of herbicide action in years that you are not growing lima beans in these fields.
