HERBICIDES for NOXIOUS WEEDS

Noxious Weed Recommendations: Herbicides for pasture, range, and non-crop areas, including roadside and other right-of-way that may be harvested for hay or grazed, are given a priority.

Non-Crop Areas: Non-cropland is defined for herbicide purposes as areas not used to produce food or feed crops during the time herbicide residue remains in the soil. Non-crop areas include parking lots, utility storage areas and some rights-of-way. Pasture, range and hay land are cropland.

Herbicides: Herbicides are listed by trade name except where the active ingredient is available in several products. The common name (in parentheses) follows the first listing of the trade name. Product labels for the same active ingredient vary. Herbicides included are those considered for most situations and those generally available. The order in which herbicides are listed does not reflect control results. Right-of-ways are frequently grazed or used for hay, therefore grazing and haying restrictions should be considered when selecting herbicides.

Video: Designing a Robotic Berry Picker

Since blackberries must be harvested by hand, the process is time-consuming and labor-intensive. To support a growing blackberry industry in Arkansas, food science associate professor Renee Threlfall is collaborating with mechanical engineering assistant professor Anthony Gunderman to develop a mechanical harvesting system. Most recently, the team designed a device to measure the force needed to pick a blackberry without damaging it. The data from this device will help inform the next stage of development and move the team closer to the goal of a fully autonomous robotic berry picker. The device was developed by Gunderman, with Yue Chen, a former U of A professor now at Georgia Tech, and Jeremy Collins, then a U of A undergraduate engineering student. To determine the force needed to pick blackberries without damage, the engineers worked with Threlfall and Andrea Myers, then a graduate student.
