The first sighting of sugarcane aphids in sorghum was confirmed March 21 in Hidalgo County. The colonies found were small and the field had not reached an economic population, but farmers in the region are encouraged to start scouting all sorghum.
A Section 18 has been granted for the use of Transform in Texas. While other regions are only starting the pre-plant process, NSP encourages farmers to educate themselves on pre-plant considerations, which includes finding a tolerant hybrid.
The Sorghum Checkoff website updated a list of sorghum hybrids that have been identified over the last two years to have tolerance to the sugarcane aphid. The list is based on university and other independent trials and will continue to be updated as new data is made available. Producers are encouraged to check with seed companies on the adaptability of these hybrids for specific regions.
Research has clearly shown the advantage of planting a tolerant hybrid for sugarcane aphid management. However, these tolerant hybrids must still be scouted and sprayed for the sugarcane aphid if and when the threshold is reached.
