Herbicide applications: finding a balance between drift control and efficacy

The effectiveness of a herbicide application relies on two factors, (i) maximizing the
biological effect, and (ii) minimizing environmental contamination through off-target spray movement. These two factors are often in competition with one another, like being on opposite sides of a seesaw. As a result, herbicide applications have become more challenging and reductions in weed control have been observed due to the current emphasis on reducing spray drift through more restrictive herbicide labels and increasing spray droplet size.
