Has anyone used Merit 2.5G with any success as a preventative app, on the very light side of application? We gave an estimate for treating 30 or so azaleas, and it came out to 120 per app, which I think scared the (potential) customer off. What I was wondring is, since it was to be a preventative app anyway (lace bugs will come), would it be a sound practice to apply, instead of the labelled rate, a much lighter rate, to make the azaleas less palatable to the lace bugs, so that they move on to the next target? If not, is there another systemic herbicide that could be used for ornamentals? I know Talstar stays in soil about 30 days, but isn't taken up by the plant, so that takes that out. What other options are there, or will this idea work?
