When using DRAs, it is essential to consider the labeled rate, the proper nozzle type and size, and the correct sprayer pressure. If drift control agents are used at a higher than recommended rate, the DRA pinch the spray pattern or create too large droplets, leading to insufficient coverage. An inefficient spray pattern can also be caused by using the wrong nozzle size or spray pressure. Following nozzle manufacturers’ guidelines is necessary to ensure an effective spray pattern.
Some active ingredients require DRAs in the tank mix. Examples include the herbicides with Engenia®, XtendiMax® with VaporGrip® Technology, or FeXapan® herbicide Plus VaporGrip® Technology.
