FAQ

Questions arborists ask

What is IMA-jet?

What is the IMA-jet rate per inch of DBH?

How often can IMA-jet be applied?

Label frequency: Annual. Minimum retreatment interval 365 days. Expected protection about 12 months. Time to effect about 21 days.

What does IMA-jet treat?

The label lists 102 target pests or diseases. The treatment guides on this site that use it: sycamore anthracnose, bronze birch borer, crape myrtle bark scale, diplodia tip blight, dutch elm disease, emerald ash borer, hemlock woolly adelgid, japanese beetle, oak wilt, scale insects, spotted lanternfly, two lined chestnut borer. Each guide has the rate, the timing window, and the alternatives.

Where do these numbers come from?

The PHC Rx product catalog, built from the IMA-jet label linked above, and synced to this page from the app. The label is the legal document; if the two disagree, the label wins and the catalog gets fixed.
