Will Dominion 2L work to kill hemlock wooly adelgids?

2 trees badly infected. Big trees so I have to do the soil drench method.


Dominion 2L is labeled for adelgids and will be able to help with hemlock wooly adelgid infestations. Because hemlocks are shallow rooted, a soil drench with Dominion can be effective. Whatever method is being used to make a soil drench, whether using power equipment, a bucket or watering can, it is important to make sure the application is evenly distributed and does not run off. Soil treatments should be made when the soil is moist. Fall to early winter and spring to early summer are recommended periods for making soil applications for the HWA. It can take 2-3 months for imidacloprid products to be translocated through trees that are about 15 inches in diameter. This process may be faster or slower, depending upon the size and health of the hemlock and other environmental conditions during and after the application.  It is advisable to make soil applications of imidacloprid products to hemlocks before they become heavily infested and stressed by the HWA— to ensure good translocation through the tree.
