After early research on Fusilade in the 80s with UCCE in CA for crop use, I (aswell as my friends) now find it useful in my flower garden for selective control of annoying annual and perennial grass in Seattle's wonderful gardening climate. But it doesn't control annual bluegrass or fescues. It has some odor so wear plastic gloves. It takes more than a week to get control, but rest after that week. Prompt shipping by this online company.
