How long does it take for Fertilome Tree and Shrub Systemic Insect Drench to work?
I purchased baby twisted locust, both infected with locust borer applied this product two weeks ago. Lots of beetles on and around the trees.
When using a systemic it does take time to translocate up the tree. You can use a foliar spray like Bifen for the time being.
