Pheromone traps can be used to estimate the timing of peak flight. These traps should be placed at about 4 to 6 feet above the ground for optimal catch. Placement much higher or lower in the tree may cause as much as a fivefold decrease in catch.See full list on extension.psu.eduAlthough NAA can be used to control burr knots, this is not desirable because it forces the larvae to feed into healthy cambium at the edges of burr knots. Also, other borers, such as the American plum borer, may establish in the dead burr knots. Rootstocks M.9, M.9/MM.106, M.26, MM.106, and MM.111 show some difference in susceptibility, but only M...See full list on extension.psu.eduDogwood borer can be controlled with trunk applications of a long-residual insecticide.
