  • Deep summer ploughing of nematode infested field 2-3 times at an interval of 10-15 days during hot summer. 
  • Avoid continuous growing of vegetable crops and use non-host crops like mustard, garlic, cereals at least for 2-3 years in suitable cropping system.  Use nematode-free transplants and raise nursery in nematode-free soil. 
  • Nursery bed treatment with carbofuran @ 0.3 g a.i./m2 + bare root dip treatment of seedlings with carbosulfan 25 EC in 500 ppm for one hour before transplanting. 
  • In direct seeded crops like okra, cucurbits seed treated with carbosulfan 25 EC @ 3% a.i. w/w along with deep summer ploughing of field.  
  • Nursery bed treatment with Purpureocillum lilacinum @ 50 g/m2 for management of root-knot nematode.
  • Deep summer ploughing 2-3 times during May & June and sowing of wheat in first fortnight of November. 
  • Use of non-host crop like mustard, chickpea, green gram and coriander continuously at least two to three year. 
  • Seed treatment with rhizospheric bacteria, Azotobacter chroocococcum (Strain HT-54). 
  • Application of carbofuran 3G @ 30 kg/ha in soil at sowing time.
  • Use of cockle-free certified seed or removal of cockle from the contaminated seed either by water flotation/salt sedimentation (Wheat seed dipped in 10% salt solution for 5-10 minute).

For the management of Meloidogyne graminicola and Hirschmanniella oryzae 

  • Crop rotation with potato, groundnut and black gram. 
  • Sumer solarization of nursery beds of rice for 15 days and nursery bed treatment of rice with carbofuran 3G @ 30 g/m2 and field application of carbofuran 3G @ 30 kg/ha after 40 days of transplanting. 
  • Soaking rice seeds in 0.1% (v/v) solution of carbosulfan 25 EC reduced eggs mass production of M.graminicola. 
  • Use of bioagents, Pseudomonas fluorescence @ 20 g/m2 in nursery bed treatment.
  • Deep summer ploughing of field and seed treatment with carbosulfan 25 DS @ 3% w/w. 
  • Intercropping of green gram + sesame, pigeonpea + sorghum, chickpea + mustard in 2:1 ratio. 
  • Seed treatment with Trichoderma viride @ 10 g/kg seed before sowing. 
  • Application of NSKP @ 5 g/kg + Trichoderma viride @ 5 g/kg seed is effective against Heterodera cajani. 
  • Use of bio-agents Pseudomonas fluorescence or Trichoderma viride @ 10 g/kg seed is effective against root-knot nematode, pigeon-pea cyst nematode and lesion nematode. 
  • Chickpea seed treatment with NSKP @ 10% w/w or Trichoderma viride @ 10 g/kg seed is effective against Pratylenchus thornei.
