Spartan Charge for Lima Beans

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

There is a 24c Label for use of Spartan Charge for lima beans in Delaware (not available in other states in the region). It is for control of ALS-resistant pigweed (Group 2 herbicides). It is a lower rate of the active ingredient (sulfentrazone) than is used in soybeans. The rate will provide early-season control of pigweed, but do not expect to see significant control of most species on the label due to this lower rate. The level of crop safety is marginal with Spartan Charge and so overlaps will cause injury. Also, sandy soils or sandy knolls in fields are likely to show injury. Injury is also likely if used early-season. Under conditions of cool soils and sandy soils, less than the labeled rate is suggested. We do not have experience with Spartan Charge on lima beans under a wide range of conditions, so be cautious and consider using it only in fields with known history of ALS-resistant pigweed.
