While it may not be top of mind for every landowner, corn leafhoppers are back on our radar this season—and they’re worth watching. These tiny insects can carry and spread corn stunt disease, which affects not just commercial corn fields but also hobby plots and forage crops.

🪲 What You Should Know:

• The Pest: Corn leafhoppers feed on corn sap and carry pathogens.

• The Risk: They transmit Spiroplasma kunkelii, the cause of corn stunt disease.

• The Spread: Recent rains in parts of Texas (like Burleson County) helped suppress populations, but warm weather could bring them back quickly.

  
  

🌽 What You Can Do:

• Inspect your corn plants for leafhopper activity—look for yellowing, curling leaves, and stunted growth.

• Plant resistant corn varieties if possible.

• Remove infected plants quickly to slow transmission.

• If necessary, contact an expert about approved insecticidal options (we recommend integrating biological controls whenever feasible).
