Abstract/Contents:"Methiozolin at 0.5 lb a.i./A was applied sequentially four times at 10-14 day intervals to compare timing of applications in the fall beginning in September versus October. Amicarbazone at 0.02 and 0.04 lb a.i./A and bispyribac-sodium at 0.01 lb a.i./A were applied sequentially 6 times at 10-14 days to evaluate and determine Poa annua control efficacy beginning in the fall of 2013 to the present. In December 2013 at 1 month after the final applications were made, methiozolin caused up to 75% P. annua injury, bispyribac-sodium caused 53% injury, and amicarbazone showed no evidence of injury. In the spring 2014, methiozolin applied beginning in October exhibited nearly acceptable control of P. annua at 83% while the early timing initiated in September was similar to amicarbazone and bispyribac-sodium at 36 to 58% control. The same treatments were re-applied in fall 2014, spring and fall 2015, and fall 2016. Methiozolin applications initiated in October consistently showed improved P. annua control at acceptable levels better than 80% compared to September initiation. Amicarbazone at 0.04 lb a.i./A performed better than the lower rate against P. annua. Amicarbazone caused phytotoxicity on the creeping bentgrass golf green while methiozolin and bispyribac-sodium caused slight discoloration of the turf."
