2,4-D is a selective systemic plant growth regulator herbicide primarily used for post emergence broadleaf weed control (for example: waterhemp, ragweed, horseweed) in a variety of crops grass (monocot) crops, including corn, small grains, sorghum, grass pastures, and 2,4-D tolerant soybeans. It is also used for weed control in turf such as residential lawns, sports fields, parks, and other areas. 2,4-D is Site-of-Action 4, synthetic auxin herbicide which is a type of growth regulator herbicide.

2,4-D has long been used in agricultural and nonagricultural herbicide products. The United States Environmental Protection Agency (EPA) has approved post-emergence use of two 2,4-D products, Enlist Duo (EPA Reg. No. 62719-649, DowDuPont) and Enlist One (EPA Reg. No. 62719-695, DowDuPont), on 2,4-D-tolerant (Enlist) corn and soybeans.

In Minnesota, waterhemp has evolved resistance to several herbicide classes (for example: glyphosate, ALS, PPO herbicides). These new 2,4-D products are approved for use in Enlist corn and soybeans to control herbicide-resistant weeds such as waterhemp. Also, palmer amaranth, Amaranthus palmeri, another aggressive species in the pigweed family has been found in a few Minnesota fields in recent years. Populations of this weed with resistance to glyphosate, ALS, PPO, and HPPD herbicides have been identified in other upper-Midwestern states.

2,4-D is a volatile chemical that may damage non-target plant species through spray drift and/or volatilization (vapor drift) or misapplication. Misuse of 2,4-D products may cause serious damage to sensitive plants species including non-2,4-D-tolerant crops like grapes, trees, ornamentals, etc. Some species are extremely sensitive to 2,4-D and show injury from low very low exposure.
