Most sorghum throughout north central Kansas is past the soft dough stage, thus not susceptible to “headworms.” However, a few late-planted fields, just coming into the “boot” stage, have sporadic small colonies of sugarcane aphids (SCA) (see pic of SCA’s from Saline and Dickenson counties (pic3)). However, there seems to be significant numbers of beneficials, but these late developing fields should still be monitored as these populations can “explode” quite quickly.
