Sweet Potato Herbicide Trials - Dargaville

This study evaluated the effectiveness of a range of herbicides for use on sweet potato in the Dargaville region. The three herbicide treatments applied all produced various degrees of leaf chlorosis or leaf burn in the sweet potato plant without causing plant death. None of the other herbicide treatments or the hand-weeded treatment showed evidence of any damage to the sweet potato plants.
