FAQ
Questions arborists ask
What is Vigor 53™?
Vigor 53™ is a nutrient from Mauget with Monopotassium phosphite as the active ingredient. It is applied by trunk injection.
What is the Vigor 53™ rate per inch of DBH?
The label sets the dose by DBH band, not a flat rate per inch. A 8 inch tree takes 30 to 38 mL low, 30 to 38 mL medium, 30 to 38 mL high (label band 8 to 10 in). The PHC Rx calculator reads the band for the tree in front of you and sets the number of injection sites.
How often can Vigor 53™ be applied?
Label frequency: As needed during the growing season. Minimum retreatment interval 365 days. Expected protection about 12 months. Time to effect about 14 days.
Where do these numbers come from?
The PHC Rx product catalog, built from the Vigor 53™ 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.
