Test your pest management knowledge by clicking on the GUESS THE PEST logo and submitting your best guess. For the 2019 season, we will have an “end of season” raffle for a $100.00 gift card. Each week, one lucky winner will also be selected for a prize and have their name entered not once but five times into the end of season raffle. A lucky winner will also receive a heavy duty sweep net.
This week’s guess the pest challenge comes from a sorghum field near you. While looking for headworms and aphids, this leaf discoloration was observed on lower and some mid-canopy leaves of boot stage to head stage sorghum. What is causing it?
