greetings, i live in central indiana (zone 5) and have already applied "step 1" pre-m to my roughly 1/3 acre yard. this was done about 2 wks. ago. over the past couple of weeks, i'm noticing many (a variety) broadleaf weeds...some that appear to be leftover from last year as well as weeds (chickweed???) that seem to be new for 2008. 2 days ago, I bought some weed-b-gone max in both the pre-mixed form (it came in 1/2 gal container with spray gun/wand) as well as some of the weed-b-gone concentrate. I applied the pre-mixed but was only able to "spot treat" some of the areas (buckhorn???) due to the spray-stream coming out of the gun. after a couple days...it appears this did not produce the desired results. My problem is I need a more complete coverage and thought I could use one of those Ortho dial-a-spray contraptions and fill the container with the concentrate weed-b-gone max. this is the thing that hooks to your garden hose and allows for a greater/wider distribution....higher volume of liquid weed killer. This is the only thing i know to do to attack the chickweed that seems to be spreading all over the place. does anyone have experience using the Ortho dial-a-spray with weed-b-gone max???? will this work better for me???
