Winged SCA in Hill County

Winged sugarcane aphids have been found in Hill County in the Johnsongrass where they overwintered. These aphids have the ability to move to sorghum fields, as well as other Johnsongrass patches and volunteer sorghum. It is recommended to being scouting sorghum for the aphids 3-4 weeks post-emergence. Most seed treatments should provide protection for at least 4 weeks, but varying environmental conditions (rain, soil moisture, ect) may affect their potency.

Because effective control depends on timing sprays according to population numbers, early scouting may be essential in preventing economic damage in fields.
