Is the mixing ratio the same for both types of trees when used as a soil drench? (3-12 gr/in DBH). As a rule of thumb, since I plan on going with 12 grams/inch to get the problems under control, is it probably ok to go with the lower end of the range for water (1-4 pints/in DBH) to save lugging too many 5 gallon buckets around?
When soil drenching using Safari 20SG Systemic Insecticide with Dinotefuran, it is important to use enough water to thoroughly saturate the roots from the trunk out to the end of the tree line. Water is the carrier so using too little amounts of water will not thoroughly disperse the active ingredient like it's intended to do.
Per the Soil Drench Remarks on page 12 of the product label, it is advised to adjust drench volume based on soil type, soil moisture and thickness of mulch so that product is moved into root zone
