Special artificial light sources have been designed and constructed to investigate the photo‐decomposition of rotenone in controlled conditions. The various factors that affect the decomposition are investigated, and the rates of decomposition of rotenone and derris deposits on exposure to sunlight and the artificial light sources are determined. The rates of decomposition indicate the reaction to be of the first order. From the data obtained, the period over which the deposits are likely to remain active under field conditions is estimated.
