Abstract/Contents:"Indaziflam (BCS-AA10717) is a new herbicide being developed for pre-emergence control of annual monocot and dicot weeds in turf, ornamentals, and industrial areas. Indaziflam is a cellulose biosynthesis inhibitor (CBI) and is classified as a HRAC Group L herbicide. Indaziflam is the most active CBI herbicide discovered to date, and therefore requires very low rates for effective weed control. It works by inhibiting crystalline cellulose deposition in the cell wall which severely affects cell wall formation as well as cell elongation and division. Thus, only actively growing meristematic regions are affected by Indaziflam. Indaziflam acts primarily as a pre-emergent herbicide, but has early post-emergent control of some weed species such as annual bluegrass (Poa annua). However, best weed control of most weed species is achieved when indaziflam is applied prior to weed germination. Perennial weeds emerging from rhizomes or roots will not likely be controlled. Indaziflam has a water solubility of 2.8 mg/L with low soil mobility and moderate soil degradation rates. Use rates of indaziflam range between 30 and 100 g ai/ha depending on the weed species, use-site, and pattern of use. Since 2003, indaziflam has been evaluated in over 150 trials for turfgrass tolerance and weed control. Sprayable (WP and SC) and fertilizer granular formulations have been evaluated at rates of 12.5 to 150 g ai/ha. Warm season turfgrasses such as bermudagrass (Cynodon dactylon), centipedegrass (Eremochloa ophiuroides), seashore paspalum (Paspalum vaginatum), St. Augustinegrass (Stenotaphrum secundatum), and zoysiagrass (Zoysia spp.) show excellent tolerance to indaziflam. Cool-season turfgrasses generally do not have sufficient tolerance to indaziflam and will not be labeled for use. Primary weeds controlled include large and smooth crabgrass (Digitaria spp.), goosegrass (Eleusine indica) annual bluegrass, annual sedges (Cyperus spp.) and kyllinga (Kyllinga spp.) as well as many broadleaf weeds. In ornamentals, indaziflam was safe when applied as a directed spray in field grown ornamentals or sprayed over-the-top of dormant, woody deciduous plants and conifers. Several granular formulations of indaziflam have been evaluated for weed control in newly planted container ornamentals. Woody plants show very good tolerance of indaziflam at rates up to (60 to 90 g ai/ha). Indaziflam also provided excellent residual control of many annual weeds including several difficult to control weeds such as eclipta (Eclipta alba) and doveweed (Murdannia nudiflora). Initial uses for industrial vegetation management include forestry, roadside, and railroad rights-of-way. Trials have been conducted for several years evaluating indaziflam at rates from 50 to 150 g ai/ha alone and in combination with other residual and postemergence herbicides for weed control in bareground situations. Indaziflam is currently pending an expected registration with EPA in 2010."
