I have used the 1.47% imidacloprid as a drench for trees and shrubs with success for 3 yrs.
I see that you have Dominion which is 21.4% conc. of imidacloprid. Can this be diluted to the 1.47% for safe drench for trees and shrubs. If so, what is the dilution rate and wouldn't this be more cost efficient for me.
Dominion 2L would be mixed following the instructions on the product label. You should use 0.10.2 fl. oz. (3 to 6 mL) of Dominion 2L per inch of trunk diameter (or foot of shrub height) (D.B.H.) diluted in 1 pint - 1 gallon of water per inch of trunk diameter or foot of shrub height. You would not be able to dilute to a 1.47% as it is a stronger product and the percentage of active is different when diluted.
