Crop Protection

  • Among the borer pests, early shoot borer (Chilo infuscatellus) causes damage in young shoots during March to June. Trash mulching on ridges during 10 days after planting and intercropping green gram reduces the shoot borer incidence. Increasing the sett rate by 30% over the recommended rate effectively compensate the yield loss due to shoot borer damage in the late planted sugarcane crop
  • Release of egg parasitoid Trichogramma chilonis @ 2.5 cc/ha at fortnightly intervals for six times commencing from fourth month onwards effectively checks the incidence of internode borer.
  • Detrashing of cane during 5th and 7th months decreases the infestation of internode borer, mealy bugs, white fly, scales and Pyrilla.
  • Soil drenching of imidacloprid17.8 SL@ 250 ml / ha in root zone of affected cane was very effective in reducing white grub population to a tune of 83.64 per cent and recorded highest cane yield of 105.42 t /ha.
  • Application of press mud @ 15 t/ha or neek cake @ 2t/ha or poultry manure @ 2 t/ha before last ploughing is recommended for reducing the nematode population.
  • Application of Paecilomyces lilacinus or Pochonia chalamydosporia @ 20 kg /ha at the time of planting mixed with moist FYM or cured pressmud is recommended for reducing the nematode population.
  • Sett treatment with 125 g of carbendazim 50 WP in 250 litre of water along with 2.5 kg of urea for 5 minutes to manage red rot and sett rot.
  • Sett treatment with Trichoderma viride (tv 1) @ 4 g/l or Pseudomonas fluorescens (Pf1) @ 10 g /l of water for 10 minutes to manage red rot disease.
  • Smut disease (Sporisorium scitaminea) has two epidemic periods viz., May to June and October to November and can be managed by treating the setts with aerated steam therapy @ 50°C for 1 hour.
