Annual Tree & Shrub Insect Control Concentrate provides year long control to trees and shrubs for listed insects on the label. It will not offer immediate contact kill for those pests listed. Systemics take time to work through targeted area. We do carry a residual insecticides such as Talstar P or Demand CS that can be applied to listed areas once monthly to the exterior of the structure on non-edible foliage and will eradicate cankerworms (inchworms) as well as other listed insects on the product label. You will treat on a dry day when you are not expecting any rainfall.
You can use Annual Tree & Shrub Insect Control Concentrate on trees that are larger than 10" in circumference: you will just use more product. So you would still use 1 oz of concentrate per inch of trunk circumference diluted in water and applied around the base of the tree (not applied directly on the bark).
This product does have a low percentage of active ingredient. If you have large trees, then we suggest using a systemic product with more active ingredient in the concentrate so that you will not need as much product for each tree. Dominion 2L is a great option: you would use 0.1 - 0.2 oz of concentrate per inch of trunk diameter (not circumference) and apply the same way as a drench around the base of each tree.
If you are using Bonide Annual Tree & Shrub Insect Control Concentrate for your tree, you would use 171 ounces of the concentrate to treat a tree which has a circumference of 171 inches. The exact amount of water is not as important as using the correct amount of insecticide; you just want to be sure you are using enough water to apply the insecticide all the way around the base of the tree. We recommend a minimum of 2 gallons of water for a tree that size.
Annual Tree & Shrub Insect Control Concentrate is not labeled to control webworms, you can instead use Summit Biological Caterpillar and Webworm Control.
Annual Tree & Shrub Insect Control Concentrate should not be applied near a koi pond or where there is drift as it is toxic to aquatic life.
Annual Tree & Shrub Insect Control Concentrate is not labeled to be used on anything edible would not be recommended. Instead you can use the Fruit Tree and Vegetable Systemic Soil Drench on listed vegetables which has the same active ingredient at a lower percentage so is safe.
Yes, Bonide Annual Tree & Shrub Insect Control Concentrate is labeled to treat for psyllids.
