Abstract
The DUPONT™ product CORAGEN®, (chlorantraniliprole) was labeled for use to control insects in flue-cured tobacco production in the United States in 2010. Coragen is recommended for use on tobacco to control tobacco budworm (Heliothis virescens), tobacco hornworm (Manduca sexta) and tobacco splitworm (potato tuberworm) (Phthorimaea operculella). Research trials have been conducted in Georgia in 2010, 2011 and 2012 to evaluate the use of Coragen for control of a variety of worms which attack tobacco. Trials have demonstrated the effectiveness of Coragen applied with the water at transplanting for control of tobacco budworms, cutworms and most recently tobacco splitworms. Although populations of tobacco budworms and tobacco hornworms occur annually and require management by tobacco growers, the occurrence of cutworm and tobacco splitworm varies with the season. Cutworm and splitworm populations have recently been encountered in areas where trials have been conducted and valuable data have been accumulated on these insects as well. In this trial transplant water treatment with Coragen was found to give control of tobacco splitworm.
