The Control of Small Tea Tortrix (Adoxophyes privatana WALKER) by Parathion (Part 1)

We examined some problems about the control.of the small tea tortrix by parathion.1.Parathion was more effective than the other organic phosphorous insecticides.2.The best result was obtained in controlling it, when 0.04-0.02% parathion was used at the rate of 160-230 gallons per acre.Parathion emulsion and wettable powder were nearly equal in effectiveness to control the small tea tortrix, and parathion dusting seemed not to be so effective as spraying.3.Parathion emulsion mixed with Bordeaux mixture (0.4%, ) or Zineb (1/50C) was so effective for controlling the small tea tortrix.
