Abstract/Contents:"Downy brome (Bromus tectorum L.), rattail fescue (Vulpia myuros (L.) C.C. Gmel.), alkali grass (Puccinellia distans (Jacq.) Parl.), and annual bluegrass (Poa annua L.) are problematic grass weeds in the Kentucky bluegrass and perennial rye grass seed production systems in the Inland Pacific Northwest. Management relies extensively on currently labeled herbicides for PRE and POST emergence control especially in the first year of crop establishment. Recent research identified two promising active ingredients, pyroxasulfone and indaziflam, for use in turfgrass, and suggested both were effective for grass weed control when applied PRE. However, the specific effects on Kentucky bluegrass and perennial ryegrass seedling emergence and stand establishment remained unclear. When following a PRE-application of mesotrione, POST applied herbicides like glufosinate also appeared to be safe for both Kentucky bluegrass and perennial ryegrass once seedlings were established while providing some control of weedy grass species. We evaluated the safety and efficacy of PRE-applications of pyroxasulfone or indaziflam in combination with mesotrione in field trials of Kentucky bluegrass, perennial ryegrass, downy brome, rattail fescue, alkali grass, and annual blue grass at Central Ferry, WA and Othello, WA, in 2017. Results indicate that both pyroxasulfone and indaziflam with or without mesotrione provide partial to complete control of all four grass weed species eight weeks 25 after treatment. Treatments also reduced Kentucky bluegrass and perennial ryegrass seedling emergence and stand establishment compared to untreated checks. However, perennial ryegrass was less sensitive than Kentucky bluegrass to herbicide treatments suggesting there may be some natural variation among species."
