Methiozolin is a new turf herbicide that controls annual bluegrass (Poa annua) in various cool and warm season turfgrasses.

Unquestionably, annual bluegrass is the single largest weed problem in golf courses, and there has been no working chemical solution particularly in cool-season grasses. Methiozolin controls both annual and perennial biotypes of annual bluegrass, by POST-emergence application.

Methiozolin has PRE-emergence activity, thus provides residual control of annual bluegrass, crabgrass (Digitaria sp.), and goosegrass (Elucine indica) as well.

Methiozolin does not belong to any existing chemical category and has a new mode of action; inhibits cell wall biosynthesis. It controls ALS herbicide-resistant annual bluegrass. Therefore, Methiozolin can be an essential component in herbicide rotation or replacement.

Methiozolin has excellent safety to virtually all established turfgrasses including creeping bentgrass, Kentucky bluegrass, perennial ryegrass, fine fescues, bermudagrass, zoysiagrass, centipedgrass, seashore paspalum, kikyuyugrass, St. Augustinegrass etc.

Methiozolin herbicide is extremely safe and environmentally friendly with excellent regulatory profiles. The active ingredient is practically non-toxic, non-mutagenic, non-teratogenic, rapidly degrades, and soil leaching is not a problem. The EC formulation (250 g/L) is easy to dilute, a small size to handle, produces no unpleasant odors, and contains no contaminating dyes or residues.

Methiozolin was launched in April 2010 in Korea and is presently being developed for use in the USA, Japan, and Australia.

Methiozolin was registered as a non-crop herbicide in turf as of March 31, and launched in April 2010 in Korea, under the brand name of ¡°POA-BAKSA¡±.

POABAKSA is currently a 25% (w/w) EC formulation, and a new SC formulation will be available soon.

POABAKSA uses were equally distributed among creeping bentgrass putting greens, Kentucky bluegrass fairway and tees, putting green-surrounds of zoysiagrass fairways.

The number of golf courses in South Korea is not large, but the environments are greatly diverse ranging from sub-tropical to mountainous. This range of micro-climates has potential to serve as prototypes for Methiozolin development in other countries.

Methiozolin was first tested in 2009 at Virginia Polytechnic Institute and State Univ., Blacksburg, Virginia and Auburn University, Auburn, Alabama. The test results will be openly accessible through University turf field days, academic societies, and various professional conferences,

The brand name of methiozolin will be PoaCure. PoaCure is in Experimental UsePermit since 2014. Full registration is on-going.

PoaCure obtained full registration in June 2016 and now commercially available through SDS Biotech KK.
