Field trials with soil solarisation showed a reduction of 43.8 and 24.3 per cent in the population of Rotylenchulus reniformis and Helicotylenchus indicus respectively. Application of Calotropis leaves @ 80 t/ha in the first year gardens was found significantly better than neem and castor leaves which was proved as effective as carbofuran granules in reducing the nematodes populations.
In the second year gardens. significantly minimum root gall incidence (27 galls/5g root) was recorded when neem cake was applied @ 2 t/ha compared to check plots (70 galls/5g root). An increased leaf yield of 29.6 percent and 25.9, over check was recorded in the plots treated with saw dust @ 2 t/ha + N.P.K. and neem cake @ 2 t/ha respectively.
