I'm trying to understand 2,3,4,5 and 8 #2, stronger concentrations will kill better. That's why roundup for brush and ivy is a stronger concentration so I have to assume it's going to kill grass and weeds better #3, the direrctions tell us to spray the entire plant, underside too. I assume that could be called drenching or soaking. #4, if a plant is in a drought condition, any water detected will be absorbed faster and better for the plant to survive. With chemical in the water, I have to assume the plant will absorb the chemical faster also and will die quicker. #5, I'll go back to what I said in #3 #8, Roundup quick pro is a highly concentrated product designed to be mixed to lesser dilutions. How can that product be "the bomb" if you're diluting it to the correct dilution rate as you recommend in #2, making it no better that any over the counter premixed Roundup product?
