Ten field trials were conducted during the year 1963-64 with different formulations of 11 insecticides to find out the control measures of flush-worms infesting young tea shoots. Observations were first noted on 3rd/4th day after spraying and thereafter at weekly intervals. Folidol (E605 & M50), Diazinon (60E & 40W), Gusthion 20E. C., Dipterex (FL1/90, E50, SP80 and WP 50), Lebaycid 50 E.C., Rogor 40 and (Endrin 20E.C.) gave control of the pest about a week after spraying. Four sprayings at weekly intervals with Folidol E605 & M50, Gusathion 20, Diazinon 60E, Dipterex E50, SPRO & WP50 gave highly significant control of the pest upto a fortnight after 4th spray, after which the infestation again increased indicating that weekly sprayings must be continued to check it.
