170. RESIDUEREPORTONAPPLESHARVESTED FROMTREESWHEREAMINOTRIAZOLE SPRAYSHAVEBEENAPPLIEDTO THEGROUNDCOVER. Oscar E. Schubert l . In 1957, an experiment was initiated at the West Virginia University Horticulture Farm near Mo~antown, to ascertain the effects of several herbicides on .apple trees (a), With more t'requent use of herbicides addi tiona! int'ormation would be needed regard1ng their harmful or beneficial effects q>on tree and fruit growth. Since the tolerance of plants to herbicides is often critical, herbicides were applied at the cODIlIOnly recommended rates and a.t rates five times greater. An orchardist or r~ 'WOrkers would be more likely to overspray) by trying to cover the area thorougb.ly or by a calibration error, than he 'WOuldby adding five times as much of the herbicide to the spray tank. For these reasons the application rates were 200 gallons per acre for the basic rate and 1

According to the C. W. England Laboratories, "The U. S. Food and Drug Administration considered any sample which bas a response of less than 0.15 p.p.m. as negative. Apple pigments and other material in apples are known to come through and give low false positive responses . 11 If Stayman samples 5,,6, and 1 are compared with each other, disregarding sample 2 and 8 with 0.00 residues, it may appear that a relationship exists between rate of ATAapplication and ~ residue in the fruit. In these three samples from 0,4, and 20 pound per acre tree plots the ATAresidues were 0.00" 0.051 and 0.09 p.p.m., respectively. '!'his might indicate an uptake and translocation of' smll ammmts of ATAto the fruit. With this possibility in mind, chemists at the Food and Dl'ug Administration developed a more sensitive method for ATA determinations known as the FDARapid Method using the Bratton-Marshall procedure.
