Symptoms and damage

Green plant hoppers are sap-sucking insects. The young insects feed on plant leaves and the older insects feed on the stem. Feeding can cause leaf speckling damage and transmission of plant diseases.

Prevention and control tips

  • Do not usually require control.
  • Chemical insecticides.
  • Neem.
  • Organic pyrethrum.
  • Spray oil.

Natural predators
