Organic amendments in management of Meloidogyne javanica on groundnut

Pot experiments with organic amendments for the management of Meloidogyne javanica infesting groundnut revealed all plant products viz. Azolla (Azolla pinnata R.Br). powder of dry leaves of pink ancl white flower periwinkles (Catharanthus roseus (L.)G Don.) and vilayati mendi (Clerodendron inerme L.) and cakes viz, castor, karanj, mahuva, mustard, neem and piludi, fresh and dry Azolla. FYM and poultry manure showed improved growth of the crop and also reduced nematode population in comparison to control. Treatment with ‘Azolla’ was the best in these respects as compared to all other amendments. Higher dose, of 3000 kg/ha was more effective than the lower dosages tried.
