The sugarcane aphid has become a chronic pest of forage and grain sorghum in Alabama. Best management practices for this pest include planting as early as soil temperatures permit, using an insecticide seed treatment, using a tolerant hybrid, then scouting sorghum weekly for sugarcane aphid. Dr. Brent Bean, Director of Agronomy, United Sorghum Checkoff Program, says that "most agronomists suggest waiting to plant sorghum until the minimum daily soil temperature is 60°F and the forecast for the next 10 days is for warm weather." Information on tolerance of sorghum hybrids to sugarcane aphid can be found at the United Sorghum Checkoff Program website. (www.sorghumcheckoff.com) When sugarcane aphid populations exceed threshold (when 20-30% of plants have an average of 50 aphids per leaf), two insecticides are available for use: Sivanto Prime and Transform WG. Transform WG in 2017 is available because of a special Section 18 label. More information on sugarcane aphid can be found in this ACES publication:
