Abstract:

Azinphosmethyl, diazinon, or parathion applied at the pink- bud stage 'McIntosh' apple, and DDT applied at the petal-fall stage gave good control of the fruit-tree leaf roller, Archips argyrospilus(Walker), on McIntosh, 'Delirious,' and 'Spartan' apple trees. Dormant oil-ethion at the 1/2-inch green stage and endosulfan at the petal-fall stage were less effective and aldicarb as a soil treatment was ineffective. DDT and endosulfan as pedal-fall sprays gave excellent control of the white apple leafhopper, Typhlocyba pomaria McAtee.

A pink-bud spray of azinphosmethyl, diazinon, or parathion and a petal-fall spray of endosuIfan could be used in conjunction with a sterile-codling moth pro!(ram to control fruit- tree leaf roller and white apple leafhopper. In addition, the above materials and timing of sprays did not affect either phytophagous or predator mites.
