Carbofuran was evaluated for control of Heliothis virescens (F.) and its effects on yield and quality of flue-cured tobacco in South Carolina. Pretransplant broadcast and posttransplant sidedress treatments gave a range of control from inadequate to excellent. In all experiments, carbofuran aided in control of tobacco budworms, but yield data from carbofuran-treated tobacco was not consistent. When compared to untreated tobacco, yields from carbofuran treatments ranged from a reduction of ca. 31b/acre to an increase of ca. 500 lb/ acre. In all experiments, yields from carbofuran- treated tobacco were less than from tobacco treated with foliar applications of insecticides for tobacco budworm control. Although insect damage was sometimes apparent when carbofuran alone was used, a carbofuran combination treatment plus a nematicide such as Mocap® or Telone® increased yields, and the increases were comparable to combination treatments of standard nematicides plus foliar insecticides. Tobacco quality was good for carbofuran-treated tobacco and flowering dates were about the same as for standard nematicides plus foliar insecticides for tobacco budworm control.
