Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants I am not lazy, but I am

I have Curly Leaf PW in the pond and I just spent some quality time weed razoring it. I have purchased Sonar AS and am now ready to put it in the pond. I swear that when I bought it, the ad showed a guy just dumping it in his pond. I thought, "great," just like my pond dye. The label says that it needs to be sprayed.

I guess my lazy question is can I just dump it it several places and it will dissipate and fill the pond, or do I have to set up the sprayer and hit all of the little areas (some in the center)? Sonar is expensive, so I do not want to waste it.
