The effects of growth retardants on infestation by Potyphagotarsonemus tatus (broad mite) on cotton (Gossypium hirsutum L. cv. IAC-17) plants was studied. Cotton plants were sprayed with (2-ch1oroethy1) trimethylammonium chloride (CCC) 250, 350 and 450 ppm, and with 1,1-dimethyl-piperidinium chloride (Pix) at concentrations of 84, 167 and 250 ppm. Growth retardants did not give effective control of Potyphagotarsone mus tatus but application of Pix 167 ppm showed a tendency to reduce mite attack.
