Grain Sorghum Many insects attack sorghum and small grains in Mississippi. Some producers let insects rob them of profit because they do not use adequate pest control. Planting at the proper time is important.
Check fields weekly or more often, depending on pest and damage.
Apply proper control measures according to economic thresholds for optimum economic returns. Insecticides are most effective if you apply them when insects are in early growth stages and the economic threshold is reached. They are pale green with a darker green stripe down the middle of the back. The legs and cornicles are also green, except for the tips that are usually black. Greenbug infestations in small grains are often first detected by the red- spotted, yellow, or orange leaves that appear on a few plants in localized spots within a field.
