Host range<\/strong>: Rice<\/a>, sugarcane<\/a>, grasses
\nDamage symptoms: <\/strong>Nymphs and adults congregate at the base of the plant above the water level and suck the sap from the tillers.  The affected plant dries up and gives a scorched appearance called \u201chopper burn\u201d.  Circular patches of drying and lodging of matured plants are typical symptoms caused by this pest.  It is the vector of grassy stunt, ragged stunt and wilted stunt diseases.
\nETL:<\/strong> 8-10 Nos.\/hill or 20 Nos.\/hill  when spider is present at 1 No.\/hill<\/p>\n

Management<\/strong><\/p>\n

    \n
  1. Use resistant varieties.<\/li>\n
  2. Avoid close planting and provide 30 cm rogue spacing at every 2.5 m to reduce the pest incidence.<\/li>\n
  3. Avoid use of excessive nitrogenous fertilizers.<\/li>\n
  4. Control irrigation by intermittent draining.<\/li>\n
  5. Set up light traps to monitor and control pest population.<\/li>\n
  6. Release of natural enemies like wolf spider, Lycosa pseudoannulata and green mirid bug Cyrtorrhinus lividipennis.<\/li>\n
  7. Avoid use of insecticides causing resurgence such as synthetic pyrethroids, methyl parathion, fenthion and quinalphos.<\/li>\n
  8. Drain the water before the use of insecticides and direct the spray towards the base of the plants.<\/li>\n
  9. Spray neem seed kernel extract 5% (25 kg\/ha) (or) neem oil 2% (10 L\/ha).<\/li>\n
  10. Spray imidacloprid<\/a> 17.8 SL 125 ml or buprofezin<\/a> 25 SC 325 ml or or acephate<\/a> 75 SP 625 g or or \/ha.<\/li>\n<\/ol>\n
