A South-wide Rate Test of Esfenvalerate (Asana® XL) for Cone and Seed Insect Control in Southern Pine Seed Orchards

As many as five monthly applications may be required each year to protect southern pine seed orchards from coneworms, Dioryctria spp. Insecticides targeted to control coneworms usually provide control of two other pests, the leaffooted pine seed bug, Leptoglossus corculus, and the shieldbacked pine seed bug, Tetyra bipunctata. Esfenvalerate (Asana® XL) is a pyrethroid insecticide that is effective for both coneworms and seed bugs. Aerial application of the maximum labeled rate of esfenvalerate can cause outbreaks of secondary pests such as scale insects and mealy bugs. These secondary insect outbreaks promote growth of unsightly sooty mold and reduce tree vigor and growth.
