We normally would not recommend to apply Talstar P over the same area a Dominion drench has been applied. It could cause the Dominion to pick up some repellency. Now, if you are only looking to apply a foliar spray to a tree or shrub you drenched with Dominion that would be just fine as long as that plant is non-edible.
When using Dominion 2L Termiticide Concentrate for a soil drench, you typically start drenching about 12 inches from the base of the tree and out to the drip line. In Texas, you will apply this product as a soil drench before the pollen has shed around mid April. You can contact your local cooperative extension for specific timing.
Dominion 2L should not be used on any citrus fruits such as lemon or lime. You can use Monterey Fruit Tree and Vegetable Systemic Soil Drench as a systemic treatment for lemon, lime, and other listed fruit trees.
Dominion 2L is a great option for a soil drench on your trees. There are no resistance issues with this product that we have encountered.
We do also have products such as Zylam and Safari that can be used for emerald ash borers.
When using Dominion 2L as a soil drench to trees and shrubs it should last for a full 12 months, however if you have a heavy pest problem you can retreat the soil after 6 months.
