Field studies were conducted in North Carolina to determine the critical period of weed control (CPWC) for Italian ryegrass winter wheat. Soft red wheat was planted late fall 2017 and 2018 no-till fields near Salisbury, NC. Treatments consisted allowing weeds grow from crop emergence different intervals until removal (“weedy”), maintaining “weed-free” conditions same intervals, then letting emerge compete with duration season. In 2017, occurred two-week up 18 weeks after (WAE) three-week WAE...
Abstract Field experiments were conducted at Clayton and Rocky Mount, North Carolina, during the summer of 2020 to determine growth fecundity Palmer amaranth plants that survived glufosinate with without grass competition in soybean crops. Glufosinate (590 g ai ha −1 ) was applied early postemergence (when 5 cm tall), mid-postemergence (7–10 cm), late (>10 cm) orthogonal combinations those timings. Nontreated grown weedy (i.e., intraspecific competition), weed-free in-crop (WFIC), fallow...
Abstract Field experiments were conducted at Clayton and Rocky Mount, NC, during summer 2020 to determine the growth fecundity of Palmer amaranth plants that survived glufosinate with without grass competition in cotton. Glufosinate (590 g ai ha −1 ) was applied early postemergence (5 cm tall), mid-postemergence (7 10 late (>10 tall) orthogonal combinations those timings. Nontreated grown weedy, weed-free in-crop (WFIC) fallow (WFNC) conditions for comparisons. control decreased as larger...
Field experiments were conducted at two locations in North Carolina (Clayton and Rocky Mount) to determine the influence of row spacing planting date on critical period weed control (CPWC) grass weeds ALS-tolerant grain. Grain sorghum was planted May June 2019, with either a 38 or 91 cm using an variety. Treatments consisted “weedy” “weed-free” plots up 2, 3, 5, 7 weeks after crop (WAP) treatments weedy weed-free all season. Selection species achieved by controlling broadleaf premix...
Abstract Amaranthus tuberculatus (waterhemp) is a pervasive weed of the Mid‐west and ‐south United States not native to North Carolina but infestations in crop fields have been reported recently. has evolved resistance seven herbicide groups multiple herbicide‐resistant populations are common where species native. The A. controlled with herbicides no formal characterisation conducted date. Glasshouse dose–response experiments were determine susceptibility population collected from Surry...
