What is the best time of year to treat aphids in pecan trees using Prime Source Imidacloprid 2F T/I?

Using soil drench method on large 2-3' trees, should I spread solution evenly between trunk and drip line?

Answer:

Prime Source Imidacloprid 2F T/I is applied at 1.5 fl oz per 100 gallons of water for pecan tree applications. Make foliar applications as pests begin to build before populations become extreme. Two applications at a 10 to 14 day interval may be required to achieve control. Scout and retreat if needed. Thorough uniform coverage of foliage is necessary for optimal control. Addition of an organosilicone-based spray adjuvant at a rate not to exceed the adjuvant manufacturer’s specified use rate may improve coverage. RESTRICTIONS:  Do not apply more than a total of 18.0 fluid ounces of this product per acre per year.  Do not make more than 3 applications per year.  Allow 6 or more days between applications. Allow 7 days between last application and harvest.
