Black pepper

Late onset of monsoon by 15 days
Established plantations 
  • Mulch the basins & interspaces with green leaves.
  • Spray lime 1% or kaolinite on foliage to reduce transpiration as well as heat load.
  • Postpone new planting/gap filling
  • Irrigate the crop @ 8–10 litres/day/vine (drip irrigation) or 50 litres/week/vine (hose irrigation)
  • To prevent termite attack on live supports, drench the soil with chlorpyriphos 0.075% and spray on support up to 1 m height; repeat spray after 21 days if necessary
  • Mulch the basins & interspaces with green leaves/coir pith compost.
  • Protect young vines by providing sufficient shade.
