Much sorghum throughout north central Kansas is at least in the soft dough stage and thus has passed through the most susceptible stages for sorghum headworm infestations. However, any sorghum yet to head out will still be susceptible to these headworms as there will still be at least one more generation.
All four aphids species, corn leaf, greenbugs, sugarcane, and yellow sugarcane, are still in every sorghum field we sampled throughout north central Kansas. All populations seem to be increasing but there are relatively healthy populations of beneficials present as well.
