Abstract/Contents: | "Amicarbazone and methiozolin are herbicides with efficacy for annual bluegrass (Poa annua L.) control in creeping bentgrass (Agrostis stolonifera L.). Research was conducted to determine the effects of rooting depth and soil type on creeping bentgrass injury following amicarbazone and methiozolin applications. 'Penncross' creeping bentgrass was established in sand- and soil-based rootzones using mini-rhizotrons. Plants were treated with amicarbazone (49, 98, 196 g ha-1) or methiozolin (500, 1000, 2000 g ha-1) once root growth reached depths of 5, 10, or 15 cm. Amicarbazone was more injurious than methiozolin in both rootzones. Creeping bentgrass injury with amicarbazone measured 38% in the sand-based rootzone compared with 62% in soil. This injury was accompanied by 54 to 69% reductions in root-length density in the sand-based rootzone and 42 to 81% reductions in soil. Methiozolin resulted in <=12% creeping bentgrass injury, regardless of rootzone type or application rate, and reduced root-length density 0 to 25%. Amicarbazone applications to plants rooted to 15 cm were less injurious than those rooted to 5- and 10-cm depths. Responses indicate that methiozolin is less injurious to creeping bentgrass than amicarbazone and that rooting depth and soil type affect creeping bentgrass injury with amicarbazone." |
