Distribution, persistence and translocation of Orthene® in spruce trees after simulated aerial spray application / by K.M.S. Sundaram and W.W. Hopewell. : Fo64-37/121-1976E-PDF
"A sensitive GLC analytical technique has been developed and described for the extraction of Orthene® (acephate) and its metabolite Ortho 9006 from conifer foliage. Using this method, the dissipation rate of the insecticide on spruce foliage was determined after a simulated aerial spray application. Applied dosage of 0.28 kg AI/ha (4 oz AI/acre) yielded a mean initial deposit of 55.15 ppm on the foliage which decreased rapidly to 2.92 ppm within 5 days and disappeared completely after 32 days. The metabolite was found only in traces and the mechanism of dissipation is primarily through physical processes. There was no indication of any translocation of the chemicall into the untreated parts of the foliage"--Abstract, page i.
