Chickpea Cyst Nematode (Heterodera cajani)

Chickpea Cyst Nematode (Heterodera cajani)


  • Heterodera cajani is a widely prevalent parasite of mainly leguminous crops.
  • The second stage juveniles attack the roots and develop to produce lemon shaped white females
    protruding out of root.
  • The female deposits many eggs in a large gelatinous eggs but retains some in body, which after death turns into a brown cyst.
  • The nematode completes the life cycle in 3-4 weeks and has several generations in a single crop season.


  • The crop shows yellowing and stunted growth with poor pod formation.

Cultural Control

  • Summer ploughing of the field and crop rotation for 2-3 years with cereals may reduce nematode population densities.

Chemical Control

  • Application of carbofuran or phorate @ 1-2 kg a.i./ha may also reduce crop damage.
