Abstract/Contents: | "Herbicide mixtures often provide greater control of perennial weed species than the single components alone. For example, picloram plus 2,4-D provides a 20 to 30% increase in long-term leafy spurge control compared to either herbicide applied alone. Timing of herbicide application also affects herbicide efficacy on leafy spurge. For instance imazapic fall-applied provides 80 to 90% leafy spurge control 1 yr after treatment, but only 20 to 30% control when the same treatment is applied in the spring. The purpose of this research was to evaluate long-term leafy spurge control with several herbicide mixtures applied either alone or with diflufenzopyr an auxin transport inhibitor. The first study evaluated leafy spurge control by imazapic applied in the spring (or fall) followed by picloram plus 2,4-D in the fall (or spring), picloram plus 2,4-D applied in the srping (or fall) followed by imazapic in the fall (or spring) , and all three herbicides applied tank-mixed together in the spring (or fall). The three herbicide mixture of picloram plus 2,4-D plus imazapic applied at 280 + 1120 + 70 g/ha once in the sping provided the best long-term control and averaged 98% 24 MAT (months after treatment) compared to less than 60% when the herbicides were applied alone. The same three herbicide treatment applied in the fall only averaged 15% control 24 MAT. The best split treatments were picloram plus 2,4-D applied in the spring followed by imazapic in the fall and imazapic fall-applied followed by picloram plus 2,4-D in the spring. These treatments averaged 85 to 61% control in August of 1999 and 2000, respectively. No grass injury was observed following any of the rotational treatments." |
