Abstract:14C-Monitor® (0, S dimethyl phosphoroamidithioate) was readily absorbed by the roots of 55- and 155-day-old Pinus taeda L. seedlings and translocated to the needles within 6 hours, of continuous uptake. Vermiculite-grown seedlings absorbed a significantly greater percentage of the radioactive Monitor than nutrient solution-grown seedlings. The high water content of the nutrient-grown seedlings probably accounted for the difference in the rate of absorption. In addition to Monitor, 0, S dimethyl thiophosphoric acid and two radioactive unknowns were detected. Biossay of seedlings with pales weevils, Hylobius Pales (Herbst), indicated that Monitor was present in the needles in insecticidally active quantities following6 hours of treatment.
