Obviously, the use of Panther SC in cowpea would provide great weed control but what about crop injury? Our research over several years, has suggested there is too great of an injury potential to use this product. The table below shows the level of injury (cowpea, snap bean, lima bean) that occurs with Valor at low use rates; look closely at the data as Valor rates used in our studies are well below that on the Panther SC label. Injury results are quite variable and are almost certainly tied to the amount of rainfall/irrigation occurring during the first 10 days after planting as well as soil type (% sand and organic matter). If growers do decide to use Panther SC in field peas, make certain that they understand that this is not our recommendation. In these same studies, a system of Treflan plus Dual Magnum injured each bean type less than 4% while providing excellent weed control.
