Is it too late to kill Japanese beetles with Fertilome Tree and Shrub Systemic Insect Granular 2.5%?

We have a 50 ft. tall River Birch

Answer:

Fertilome Tree and Shrub Systemic Insect Granular 2.5% takes several weeks to several months to be absorbed by the roots and then translocated throughout the tree. We recommend that this late in the season you use a topical foliage product such as Talstar P to help control the Japanese Beetle population on the tree and also on the surrounding vegetation.
