Chemical Action and Usages: General use organophosphate insecticide. The products listed are all for outdoor use on non-food crops. Orthene controls a wide range of insects, especially aphids on certain ornamental flowers, roses, shrubs and trees. Active ingredient is acephate which is absorbed by plant roots (soil treatment with granulated form) or by foliage (foliar sprays) and translocated throughout the plant. Chewing and/or sucking insects are killed on contact when they feed on plant foliage. Acephate attacks insect nervous systems. Systemic insecticides generally have longer residual persistence than non-systemic. In addition systemics are less subject to breakdown by environmental factors such as rain, wind or sunlight exposure. The Orthenex product also contains resmethrin and triflorine for an expanded label for addition insect and disease control.
