Wiregrass Research and
Extension Center

A variety of soil types and land characteristics typical of the Coastal Plain allow the Wiregrass Research and Extension Center to address problems that challenge farmers in this region. While the center has been a leader in all types of agronomic research, it is reknown for its focus on peanuts.

Current Research Updates

  • Subsurface drip irrigation continues to show great potential in providing consistent increases in cotton, corn and peanut yields. Research has documented that growers can double their yields on corn and cotton in dry years.
  • The sugarcane aphid is a pest that was first seen in Alabama in 2013 and has wreaked havoc on grain sorghum. Research has identified a few varieties with tolerance to the aphid. Also, research has shown at least three insecticides that will give adequate control of the sugarcane aphid.
  • Significant progress has been made in the control of glyphosate-resistant Palmer amaranth (pigweed). Research has confirmed that the soon-to-be-released dicamba- and 2,4-D–tolerant cotton will give producers another viable option in the control of glyphosate-resistant pigweed. Also, further research has shown that slight changes in the timing and rates on existing herbicides in the cotton arsenal will give longer residual and overall better control of this stubborn and costly weed.
