AzaSol: rate per inch, label facts, and uses

The dose is set by DBH band on the label, not by a flat rate per inch, and the table below is the app's copy of that label table. What it is labeled for, when it goes in, and how the label check reads it.

What does AzaSol treat?

The label lists 80 target pests or diseases. The treatment guides on this site that use it: bagworms, crape myrtle bark scale, pine wilt, scale insects. 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 AzaSol 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.
