    How much Optrol do I need to purchase for a one time application per tree ? I have four mature (40 year old) Ash trees which so far do not show any signs of being infected with Ash Borer.

    • The Tree Geek says:

      The amount you’d need would depend on the size of the trees in question. We measure dosages based on the tree’s diameter at 4.5 feet above the ground. One bottle of Optrol treats 20 diameter inches.

    • The Tree Geek says:

      It depends on the product, We have products like Xytect 2F, 75WSP and Optrol which would work better in the spring or falls, and Transtect which would work better in the early summer/ late spring. Which one you go with would depend on the level of infestation in the tree, the current infestation pressure around the tree, and when you would prefer to treat.

    I have been applying Optrol in every March for 4 years for my white birch tree. Could I apply Optrol twice a year, like one more time in September? Or could you please recommend any other products? My white birch has been doing good, but I see a little loss of the top leaves this year. These couple of years I have been witnessing ALL other white birch trees around my area died and disappeared, none left other than mine. I know Optrol has been protecting my tree very well, but I would like to have a full protection.

      Hello,

      It is not recommended to treat trees other than the suggested label rate. Some dieback is expected in years of heavy insect pressure, but if you maintain tree vigor it should have no problem bouncing back.
