Fields and border areas should be scouted in early summer while grasshoppers are small. Borders to sorghum fields may need treatment if grasshopper nymphs are abundant (15 to 20 per square yard) to prevent their migration into the sorghum. In the field, populations of five to eight nymphs per square yard justify treatment.
Please refer to the most recent version of the Sorghum Insect Management Guide for specific control recommendations.
