Control of the Nantucket Pine Tip Moth, Rhyacionia frustrana (Comstock), on Nursery-Grown Pine with Granular Systemic Insecticides

Container-grown mugo pine, Pinus mugo Turra. Mughus, and field-grown loblolly pine, Pinus taeda L., were utilized in 3 experiments to evaluate the effectiveness of granular systemic insecticides for control of the Nantucket pine tip moth, Rhyacionia frustrana (Comstock).

In the 1981 mugo pine study, Temik^® 10G (aldicarb), Furadan^® 10G (carbofuran) and Di-syston^® 15G (disulfoton) provided complete protection from tip moth attack 11 weeks after application. Phytotoxicity was highly visible on all trees treated with Furadan.

During the 1982 mugo pine study, Temik, Furadan and Di-syston granules applied on either November 6, 1981, or March 2, 1982 provided effective control when evaluated on May 20, 1982. Early March appeared to be a more effective application date than November for year-long control on container-grown pines.

In the 1982 loblolly pine experiment, December applications of Di-syston and Temik granules provided good control when evaluated through July. Only Di-syston provided control through August.
