With the development of transgenic crops resistant to auxin herbicides will come an increase in the use of these herbicides for weed control. This new technology will greatly aid growers that have glyphosate-resistant weeds such as Palmer amaranth (Amaranthus palmeri S. Wats) in their fields. A challenge will be with farmers that choose not to use this new technology and have susceptible crops on their farm or adjoining farms. Auxin herbicides such as 2, 4-D and dicamba are well-documented as being very injurious to susceptible crops, even at low doses. It is for this reason that research is being conducted to compare the differences in the amount of particle drift with hooded boom sprayers compared to open boom sprayers. Along with this research, various droplet sizes will also be analyzed and compared between the two sprayers.
