Green Leaf hopper management in organic basmati rice

Green leaf hopper

Green leaf hopper is found on the foliage of plants and feed there. In Northern India they appear in June-July and peak attack in September-October.The nymphs and adults of green leaf hopper are green in colour, suck sap from leaves and also inject some toxins into the plant. In Eastern and Southern India green leaf hopper are active in both Kharif and Rabi crops. The affected leaves turn brown from the tip downwards exhibiting 'hopper burn' symptoms. The adults have black spot and black patch on wings. The females lay eggs in batches on the inner surface of leaf sheath. Several weeds serve as alternate hosts for the pest. Mild infestations reduce the vigour of the plants while severe infestations cause withering and complete drying of the crop. Besides direct damage green leaf hopper (M. virescens) also transmits 'tungro' virus disease. Therefore, economic threshold level for green leaf hopper is 2 hoppers/hill in tungro endemic areas while 10 hoppers/hill in other areas. N. nigropictus acts as a vector of rice transitory yellowing, yellow-dwarf and yellow-orange leaf diseases.


  • Remove excess nurseries and weeds from the field and bunds.
  • Ensure alternate wetting and drying of the fields.
  • Avoid excess use of nitrogen.
  • Set up light traps to monitor and control population.
