title: Deterioration of DDT 50 per cent water dispersible powder packed in hessian bags during storage.
abstract: One hundred seventeen samples of DDT 50% WP received from field where supplies were effected, were tested during 1988-89 for suspensibility without accelerated storage treatment (ATS) as per ISI specifications and compared with their suspensibilities after ATS obtained during the initial testing to know the stability status of the insecticide during transit and tropical storage in the field when packed in hessian bags. Out of 117 samples tested 95 (81.2 per cent) failed and only 22 (18.8 per cent) passed the test for suspensibility indicating deterioration of the formulation in the field.
