I'm going to use Barricade for beds this year and possibly lawn as I've got a Dimension barrier now that will probably wear off in early summer depending on rainfall. I'm a homeowner with 6,800 sq. ft. of lawn and 10,000 sq. ft. beds. Using a solo 4 gallon backpack spreader, I've calibrated it to 1.25 gallons for 1,000 sq. ft. KBG lawn (with some Fine Fescue in shade), beds are perennials and annuals with shrubs/trees. I'm on LI in NY. I've read the label a few times; should I be using 1 tablespoon per thousand (.37 rate)? If I use 4 tablespoons for 4 gallons I'll end up with 1/3 extra per thousand sq. ft. On the lawn, crabgrass is no longer my enemy, its all about poa. Last year I got a lot of poa in May/June with the huge rainfalls and even got some in the fall notwithstanding a Dimension app last weekend in August. We had a very warm November and December and I think the Dimension wore off. If I switch to Barricade on the lawns I think I can get year-round coverage. One app in the beds in the spring will probably make a huge difference, I do all the work myself and spent way too much time weeding the beds last year. Any help would be appreciated.
