Abstract:The relationship of 1st instar mortality of Grapholitha molesta (Busck) to visual coverage ratings by using fluorescent dye was established for pesticide:dye ratios of 5, 8, and 11, with phosmet at 4000 ppm AI. The deposit ratings were underestimated at mortalities ≥70% for the pesticide:dye ratio of 11 but not for ratios of 8 and 5. When the phosmet concentration was varied at one pesticide:dye ratio, the low mortalities due to sparse deposits could be offset by increased phosmet concentration.
