Abstract

Purple nutsedge response to various rates and timings of imazosulfuron was evaluated in 2007 and 2008 in Abilene, TX. Bermudagrass phytotoxicity never exceeded 4% throughout the duration of the trial and all bermudagrass recovered within 7 d of herbicide application. Imazosulfuron (0.56 kg ai ha−1) followed by (fb) imazosulfuron 1 wk after initial treatment (WAIT), imazosulfuron at 1.12 kg ai ha−1, and trifloxysulfuron at 0.03 kg ai ha−1 exhibited 94 to 96% control 4 WAIT. Imazosulfuron (0.56 kg ai ha−1) fb imazosulfuron 2, 3, and 4 WAIT exhibited 99% control 4 WAIT. Eight weeks later (12 WAIT), imazosulfuron (0.56 kg ai ha−1) fb imazosulfuron 3 WAIT controlled purple nutsedge 91%, whereas similar control (82 to 84%) was observed with a single application of trifloxysulfuron and imazosulfuron (0.56 kg ai ha−1) fb imazosulfuron 2 and 4 WAIT. A single application of imazosulfuron at 1.12 kg ai ha−1 and sequential treatment with imazosulfuron (0.56 kg ai ha−1) on a 1-wk interval only controlled purple nutsedge 51 to 69% 12 WAIT. Timing of sequential imazosulfuron application was identified as an important component of the purple nutsedge control program. Waiting 2, 3, or 4 WAIT for sequential imazosulfuron applications, rather than 1 WAIT, increased purple nutsedge control 31 to 40% 12 WAIT. The highest level of purple nutsedge control (91%) was observed with applications of imazosulfuron (0.56 kg ai ha−1) fb imazosulfuron 3 WAIT applied during midsummer. However, control with this treatment was statistically similar to control with a single application of trifloxysulfuron (82%).

La respuesta de Cyperus rotundus a varias dosis y tiempos de aplicación de imazosulfuron fue evaluada en 2007 y 2008 en Abilene, Texas. La fitotoxicidad de Cynodon dactylon nunca excedió 4% a lo largo de la duración del estudio y se recuperó antes de 7 días después de la aplicación del herbicida. Imazosulfuron (0.56 kg ia ha−1) seguido por imazosulfuron 1 semana después del tratamiento inicial (SDTI), imazosulfuron a 1.12 kg ia ha−1 y trifloxysulfuron a 0.03 kg ia ha−1 lograron de 94 a 96% de control 4 SDTI. Imazosulfuron (0.56 kg ia ha−1), seguido por imazosulfuron 2, 3 y 4 SDTI alcanzaron 99% de control 4 SDTI. Ocho semanas más tarde (12 SDTI), imazosulfuron (0.56 kg ia ha−1) seguido por imazosulfuron 3 SDTI controlaron el C. rotundus 91%, mientras que un control similar (82 a 84%) se observó con una sola aplicación de trifloxysulfuron e imazosulfuron (0.56 kg ia ha−1) seguido por imazosulfuron 2 y 4 SDTI. Una sola aplicación de imazosulfuron a 1.12 kg ia ha−1 y tratamiento secuencial con imazosulfuron (0.56 kg ia ha−1) con 1 semana de intervalo, solamente controló C. rotundus de 51 a 69% a las 12 SDTI. El tiempo de la aplicación secuencial de imazosulfuron fue identificado como un componente importante del programa de control de C. rotundus. Esperar 2, 3 o 4 SDTI para las aplicaciones secuenciales de imazosulfuron, en lugar de 1 SDTI, incrementó el control de C. rotundus de 31 a 40% a las 12 SDTI. El mayorcontrol de C. rotundus (91%) se observó con aplicaciones de imazosulfuron (0.56 kg ia ha−1) seguido por imazosulfuron 3 SDTI, aplicado a medio verano. Sin embargo, el control con este tratamiento fue similar estadísticamente al control con una sola aplicación de trifloxysulfuron (82%).
