ENVIRONMENTAL FATE
Animals In mammals, propargite is hydrolysed at the sulfite ester linkage to 1-[4-(1,1-dimethylethyl)phenoxy]-2-cyclohexanol and subsequent hydroxylation of the tert-butyl side-chain. Additional metabolites are formed by further oxidation or sulfation of the tert-butyl group and oxidation of the cyclohexyl moiety. Plants Although propargite is considered a non-systemic pesticide, a small portion of the applied dose penetrates the outside layer of the foliage and undergoes the same metabolism as is observed in animals. In most fruits (apples, citrus), propargite stays mainly on the surface and, to a lesser extent, in the peel; only trace residues are detected in the pulp. Soil/Environment DT50 40-67 d (aerobic soil, pH 6.0-6.9, o.c. 1.0-2.55%, 22-25 ºC). Log Koc 3.6-3.9; no leaching in aged column study or in field dissipation studies. DT50 in water-sediment studies 1.7-2.5 d (water phase), 18.3-22.5 d (whole system). Half-life in atmosphere 2.155 h (Atkinson calculation).
Usage: Propargite was introduced by Uniroyal Inc. (now Crompton Corp.). It control of many species of phytophagous mites (particularly motile stages) on a variety of crops, including vines, fruit trees (including top fruit, stone fruit, citrus fruit), hops, nuts, tomatoes, vegetables, ornamentals, cotton, maize, peanuts, and sorghum, etc.
Application: Biochemistry Inhibits mitochondrial ATPase, which results in interruption of normal mite metabolism and respiration. Mode of action Non-systemic acaricide with predominantly contact action; some additional action by inhalation. Uses Control of phytophagous mites (particularly motile stages) on a variety of crops, including vines, fruit trees (e.g. top fruit, stone fruit, citrus fruit), hops, nuts, tomatoes, vegetables, ornamentals, cotton, maize, peanuts, and sorghum. Used at rates from 0.75-1.8 kg/ha on row crops and foliar sprays of 0.85-3.0 kg/ha on perennial fruit and nut crops. Phytotoxicity Phytotoxic to pears, strawberries, roses, and cotton under 10 inches in height. Citrus fruit and beans may also show some injury.
