Sugar Cane Aphids have become an increasingly problematic pest for sorghum growers both grain sorghum and forages. There are a few existing varieties with varying levels of resistance. MG 4595 has maintained very good resistance so far in plots and in fields in side-by-side situations. MG 4748 has some moderate resistance as well. We are evaluating other hybrids and in the next year or two should have several options to combat this pest.
Another approach that is being looked at, especially in double-crop situations, is to plant flowering “companion” species with the sorghum to attract beneficial predatory insects such as lacewings and ladybugs to feed on the aphid populations.
