Yes I am licensed to apply pesticides in Va. and I did read the label. Here is the link to the label. http://www.pbigordon.com/product_labels_turf/Trimec_Classic_Brand_Label.pdf I use a 5 gallon back pack sprayer to spot treat for weeds. How many ounces of Trimec Classic do I mix with one gallon of water? The label says mix 1.2 - 1.5 ounces with .5 - 6 gallons of water. To me that is too broad of a range. Thanks for your help.
