Abstract

Studies on crop loss due to natural infection indicated that virus affected plants yield 38 per cent, 62 per cent and 68 per cent less cardamom in the first, second and third year of infection respectively. The quantity of crop loss is related to the duration over which the plant had been infected. The yield of a well-maintained plot was affected considerably from the very first year of infection. Production of cardamom in the disease-affected plot, experienced a loss of 16 per cent at 37 per cent infection level, 44 per cent at 84 per cent infection level and 59 per cent at 98.5 per cent infection level respectively in the first, second and third year of infection.
