Soil treatment

Soil treatment

  • Soil is moistened occasionally and covered during hot summer months (March-May), hen the soil temperature rises sufficiently, to destroy inoculum of soil-borne pathogens. Soil polarization is advocated in Madhya Pradesh, West Bengal, Andhra Pradesh and TamilNadu before establishing new gardens for better plant stand and to minimize initial inoculum levels.
  • For new plantations, application of Carbofuran@ 1.5kglha or neem cake (0.5 tonneslha) + Carbofuran (0.75kglha) is also recommended to minimize initial soil nematode population. However, Carbofuran should not be recommended in established gardens at any stage because a time gap of 65-70 days as safe waiting period is required between application and harvesting of leaves.
