Injury by the herbicide increased with increasing application of oxyfluorfen; as soil content increased and clay content decreased, herbicide damage increased. These was no correlation of the diameter of the cutting to the germination rate or plant height. Fifty days after planting, the upper leaves of some plants showed N deficiency. Leaf application of 1 and 2 percent urea caused damage at the same degree of severity. (CIAT)
