Cultural pest control in Groundnut

Cultural Practices for insect pest control

  • Wherever suitable, use KSS-II, ICGS 44, ICGS 11, ICGS 37, ICGV  86325,JCG 88, CSMG 884, Chandra and Kadiri 3 genotypes which are tolerant to bud necrosis and TPT -3 against Kalahasty malady.
  • Deep ploughing in summer to expose soil - borne pathogens, white grubs, nematodes, hibernating defoliators and under ground bulbs and rhizomes of perennial weeds.
  • Crop rotation with sorghum or pearl millet or rice or maize after Kharif      crop may reduce the incidence of early leaf spot, late leaf spot, rust and Peanut Bud Necrosis Disease (PBND).
  • Sowing early by coinciding with pre- monsoon showers to avoid damage due to white grub and bud necrosis (if protective irrigation is available
  • Inter-cropping with sorghum or pigeonpea or pearl millet 3-6 rows of' groundnut and one row of inter-crop.
  • Stray planting of cowpea or soybean as trap crops for leaf miner; castor or sunflower for Spodoptera. The Sunflower acts as bird percher as well.
  • Dense cropping; (increased seed rate) to reduce bud necrosis damage and weed population.
  • Two hand hoeings at 15-20 days and 30 to 45 days after sowing for effective weed control.
  • Soil application of' caster cake/Neon cake1000 kg/ha against stern rut/termite in endemic areas only. 
  • Rogue out bud necrosis affected clump and infected plants.
  • Avoid prolonged mid season drought (>20 days) during vegetative phase (if' irrigation is available) to prevent pre-harvest infection of A.,flavus(Aflatoxin contamination)
  • Harvest at optimum maturity stage to avoid pod infection by A.flavus(neither immatured nor over - matured stage)
  • Dry pods to optimum kernel moisture level of about 7%.
  • Store in polythene - lined gunny bags and fill the top of the bag with 3 cm ht. sand. The bag should not be scaled or stitched to avoid loss of germination.
