Abstract

Studies on estimation of loss due to Anguina tritici in wheat cv. S 308 under field conditions and incidence of cookles in market grains were undertaken. The per cent infestation, on earhead basis, of earcockle and tundu ranged from 2.5 to 6.2 and 2.3 to 8.2 respectively. The per cent loss due to A. tritici, based upon number and weight of grains, ranged from 3.8 to 8.7 and 3.3 to 8.0 respectively. With artificial inoculation under field conditions, maximum loss (52.23%) was observed in 64% infestation (W/W). The per cent incidence of galls in 103 wheat samples ranged from 0.06 to 0.19, averaging 0.11%.
