Crop Protection

  • Rice + sunflower (or) rice + cowpea (or) rice + sesame cropping system with soil incorporation of either FYM (12.5 t/ha) or vermicompost (2.5 t/ha) and amendment with neem cake 250 kg / ha and azophos (2 kg/ha) (If azophos is not available,  Azospirillum
    2 kg/ha + Phosphobacteria 2 kg/ha) can be applied.
  • Increased attraction, conservation and virulent activities of Entomophages, increased the natural suppression of pests, maximum pest defender and occurrence ratios, and minimum preference ratio, moderate yield and CBR.
  • Neemazol @1000ml/ha was found to be superior against major rice pests viz., stem borer, gall midge, leaf folder, whorl maggot, brown plant hopper and green leaf hopper and recorded maximum yield 6550 kg/ha as against the untreated control (4840 kg/ha).
  • Organic amendments (FYM and vermicompost based organic amendments along with neem cake (250 kg/ha), Azospirillum (2 kg/ha), Phosphobacteria (2 kg/ha), or azophos (2 kg/ha) recorded minimum incidence of major rice pests and maximum incidence of natural enemies.
  • Consortia of PGPB viz., Bacillus amyloliquefaciens (SrRB2), pumilus (TpRB1) and B. subtilis (TrRB3) can be applied through seed, soil and foliar for the management of rice sheath blight disease.
  • Next to the chemical treatment, reduction in bacterial leaf blight incidence was observed in the treatments receiving
    subtilis through seed, seedling and foliar than control.
  • Fungicide Tebuconazole 2.5% @ 1.5 ml/l was identified as effective chemical against sheath blight infection
  • Combination of Tricyclazole 20% + Tebuconazole 16% SC @ 2 ml/l was effective against sheath rot disease
  • Difenoconazole 25% EC @ 1ml/lit was effective in controlling false smut disease.
  • Combination fungicide Trifloxstrobin 25% + Tebuconazole 50% WG @ 0.4 g/lit was effective against sheath blight disease
  • Azoxystrobin 11% + Tebuconazole 11.4% w/w SC @ 1.5 ml/lit is effective against the management brown leaf spot disease.
