Product label says mix "12-24 oz/gal depending on bark." But which one is for thicker bark, the more dilute 12 oz/gal or the more conc 24 oz/gal? Label doesn't say.
Safari 20SG Systemic Insecticide is labeled to be used as a basal bark spray on trunks of trees for borer control and the label states: "Depending on bark type and thickness, one gallon of spray solution will typically cover 65-85" of cumulative trunk diameter (1.5-2.0 fl oz per inch of trunk diameter) when applied to trunk between soil surface and 4-5 feet above soil surface." Typically the thicker the bark and more active the infestation, the higher use rate would be recommended.
