herbicides for roughstalk bluegrass control are bispyribac-sodium {2,6-bis[(4,6-dimethoxypyrimidin-2-yl)oxy] benzoic acid} and sulfosulfuron (1-[4,6-dimethoxypyrimidin-2-yl]-3-{[2-ethanesulfonyl-imidazo(1,2-a)pyridine-3-yl] sulfonyl}) urea. Bispyribac-sodium

NaN 3 treatments and LD 30 and LD 50 at 2 weeks. LD = lethal dose; NaN 3 = sodium azide; ROW = reverse osmosis water. NaN 3 has been used successfully in many plants. The effects and permeation of NaN 3 depend on the plant genotypes, nature of

an optimized concentration of PGR for producing compact plants. Dikegulac sodium [18.5% dikegulac sodium (Augeo ® ; OHP, Mainland, PA)] is a PGR labeled to reduce or break apical dominance in plant shoots and to enhance lateral branching by disrupting

PRG injury ( Dernoeden and Turner, 1988 ; Lee, 1981 ). Safe and effective annual bluegrass control with ETHO and other herbicides in CBG, however, has been inconsistent ( Dernoeden, 2002 ; Vargas and Turgeon, 2004 ). Bispyribac-sodium [2,6-bis({4

( Prunus avium ) fruit production ( Bhatti et al., 1995 ). Bispyribac-sodium is widely used in California rice fields for the control of grass species such as early watergrass ( Echinochloa oryzoides ), late watergrass ( Echinochloa oryzicola

with unacceptable Kentucky bluegrass injury ( Adams, 1989 ; Dernoeden and Turner, 1988 ). Aside from ethofumesate, there are currently no selective herbicides labeled for control of established annual bluegrass in Kentucky bluegrass. Bispyribac-sodium

accumulate sodium ( Grieve and Suarez, 1997 ). Purslane ( Portulaca oleracea L.) is not only a salt-tolerant plant ( Kilic et al., 2008 ; Shannon and Grieve, 1999 ), but also a good salt-removing crop ( Aksoy et al., 2003 ; Grieve and Suarez, 1997

). Bispyribac-sodium is an acetolactate synthase (ALS) inhibitor, which is used for pre- and postflood grass and broadleaf weed control in rice ( Oryza sativa ). It is sold under the trade name Regiment ® for use in rice at rates of up to 32 g·ha −1 ( Valent U
