stages of crop growth can result in major yields losses resulting from the competition for nutrients, water, sunlight, and space. There are limited herbicide options available for Brassica growers ( Kemble, 2017 ). Controlling weeds PRE in turnips and

Growers and landscapers are often faced with weed problems in ornamentals that cannot be controlled with selective herbicides. In landscape situations, glyphosate is mainly used as a nonselective herbicide. However, researchers have reported that

Auxin herbicides have been registered for postemergence control of broadleaf weeds in agricultural crops for more than 50 years ( Peterson et al., 2016 ). Since their initial development, different formulations of auxin herbicides, such as 2,4-D
