Abstract

Few herbicides are available that will selectively control annual bluegrass in a polyculture of bermudagrass overseeded with perennial ryegrass. Research was conducted to evaluate multifaceted annual bluegrass control programs in overseeded bermudagrass. Treatments included various combinations of four herbicides: foramsulfuron applied 2 wk prior to overseeding (WPO); ethofumesate and bispyribac-sodium (bispyribac) applied 12 or 12 followed by (fb) 15 wk after overseeding (WAO); and prodiamine applied 15 WAO to provide continued PRE annual bluegrass control. Foramsulfuron at 0.03 kg ha−1 applied 2 WPO controlled annual bluegrass 63% 28 WAO. Foramsulfuron fb ethofumesate or bispyribac applied 12 or 12 fb 15 WAO improved control to 91% or greater. Ethofumesate or bispyribac applied with prodiamine at 1.1 kg ha−1 at 15 WAO did not improve annual bluegrass control compared with ethofumesate or bispyribac treatments alone according to pairwise contrasts. Only bispyribac-containing treatments induced unacceptable perennial ryegrass injury. Bispyribac applied with prodiamine reduced perennial ryegrass cover greater than bispyribac alone according to pairwise contrast. These data indicate that ethofumesate or bispyribac applied sequentially 12 and 15 WPO can effectively control annual bluegrass in bermudagrass turf overseeded with perennial ryegrass.

Existen pocos herbicidas que pueden controlar selectivamente Poa annua en un policultivo de Cynodon dactylon sobre-sembrado con Lolium perenne. Se realizó una investigación para evaluar programas multifacéticos de control de P. annua en C. dactylon sobre-sembrado con L. perenne. Los tratamientos incluyeron varias combinaciones de cuatro herbicidas: foramsulfurón aplicado 2 semanas antes de sobre-sembrar (WPO); ethofumesato y bispyribac-sodio (bispyribac) aplicados 12 o 12 seguidos por (fb) 15 semanas después de sobre-sembrar (WAO); y prodiamina aplicado 15 WAO para proporcionar un control continuo preemergente de P. annua. El foramsulfurón a 0.03 kg/ha aplicado 2 WPO controló P. annua en 63%, 28 WAO. El foramsulfurón seguido por ethofumesato o bispyribac aplicado 12 o 12 fb 15 WAO, mejoró el control en 91% o más. El ethofumesato o bispyribac aplicado con prodiamina a 1.1 kg/ha a 15 WAO, no mejoró el control de P. annua comparado con ethofumesato o bispyribac solos, de acuerdo a contrastes en pares. Únicamente los tratamientos que contenían bispyribac, provocaron un daño inaceptable en L. perenne. El bispyribac aplicado con prodiamina redujo en mayor grado la cobertura de L. perenne comparado con solo bispyribac, de acuerdo al contraste en pares. Estos datos indican que ethofumesato o bispyribac aplicados secuenciadamente 12 y 15 WPO pueden controlar de manera eficaz P. annua en césped de C. dactylon sobresembrado con L. perenne.
