I purchased Tengard SFR from you as a pre-treatment against Pine Bark Beetles. How much per gallon?

The trees are extremely stressed due to Calif drought in the Sierra Nevada Mts, at about 4500ft. We are prohibited from watering the trees, making the situation worse. There are many infested trees in the immediate area. I will be spraying from a hand held hose sprayer, trying to reach as high as possible. Thanks for your expert advice.

Answer:

Tengard SFR is a permethrin based product and would be a great choice for helping to prevent an infestation.  The tree should be sprayed from the ground to 15 ft up the trunk to prevent future infestations. You will mix an ounce per gallon of water per 1,000 sq ft. We do carry a Chapin Slide Pump Sprayer that will reach over 30 ft! Please let us know if you need anything else.
