Management of Brown Plant Hopper [BPH] in Paddy crop

Brown plant hopper [BPH] is a small sized brown insect found mainly on the base of paddy plants above the water level. Adults and young nymphs suck the plant sap from leaf sheathes, causing yellowing of lower and then upper leaves. High population of planthoppers cause leaves to initially turn orange-yellow and turns brown burnt like later. Infestation will be in groups and areas the plants in those particular areas may in patches and called “hopper burn”. Severe uncontrolled infestation causes much losses.

BPH

Usually two species of planthopper infest paddy. These are the brown planthopper (BPH), Nilaparvata lugens (Stal); and the whitebacked planthopper (WBPH), Sogatella furcifera (Horvath).

Brown plant hopper [BPH] pest is favoured by moist, humid and warm conditions, staggered paddy planting, presence of ratoons from the previous paddy crop and high doses of urea. Planthoppers can be a problem in rainfed and in irrigated wetland environments. It also occurs in areas with continuous submerged conditions in the field, high shade, and humidity.

Brown plant hopper [BPH]  can also transmit Paddy Ragged Stunt and Paddy Grassy Stunt diseases. These diseases cannot be cured.

Symptoms of the Plant hoppers infestation

  • White eggs with crescent-shape inserted into the midrib or leaf sheath
  • Whitish brown nymphs
  • Brownish  or white adults feeding near the base of tillers
  • Yellowing , browning and drying of plants- hopperburn symptom
  • Egg laying marks exposing the plant to fungal and bacterial infections
  • Presence  of honeydew and sooty molds in the bases of areas infected

Management:

Sprays:

Osheen 0.5 gm/L + Econeem plus 1 % - 1 mL/L or Odis 2 gm/L + Econeem plus 1 % 1 mL/L may effectively control the Brown plant hopper [BPH]

Other precautions to be taken to manage the Brown plant hopper [BPH]

  • Draining the rice field for 3-4 days is recommended during the early stage of infestation.
  • Nitrogen application may be given split doses to reduce Brown plant hopper buildup.
  • Avoid close planting and provide 30 cm rogue spacing at every 2.5 to 3.0 m to reduce the pest incidence
  • Resisitant varieties cultivation may be an option to keep check on Brown plant hopper [BPH]
