Of all invasive plants that the Texas Department of Transportation (DOT) must deal with in keeping their roadways safe and aesthetically acceptable to drivers, mesquite is by far the most difficult to manage. Herbicides were the first natural choice to come to Texas DOT officials, although the choice of finding the most appropriate chemical for their purposes required a nuanced understanding of context, including roadways and aspects of the mesquite plant. In addition, officials had to contend with the fact that there is only a small window of time in which such applications are successful in the climate of southwestern Texas. Since mesquite takes up most of its water during the time between early June and late August, this timeframe was used for the distribution of the herbicide. The article relates how a chemical agent that translocates throughout the entire plant’s stem and root systems was chosen as the most useful herbicide in terms of safety and ease of distribution. It describes how a truck-mounted sprayer was used to spray the herbicide to the target areas (within approximately 10 yards of the roadway). This system, which is entirely computerized to homogenize distribution patterns, allows for long-term plant removal and only requires spot treatments annually.
