Glyphosate resistance : pollen movement within a common ragweed (Ambrosia artemisiifolia L.) population and herbicide release from common waterhemp (Amaranthus rudis sauer) plants
(University of Missouri--Columbia, 2011)
Common ragweed and Common waterhemp are native, summer annual weeds distributed widely throughout the United States. Both weed species have developed resistance to the broad-spectrum herbicide glyphosate. Research was ...
Competition and management of volunteer corn (Zea Mays L.) in corn
(University of Missouri--Columbia, 2011)
(10, 20, and 40 cm) in glufosinate-resistant or imidazolinone-tolerant hybrids, respectively. Research was conducted during 2008, 2009, and 2010 at multiple locations throughout central and northeast Missouri. Harvest inefficiencies resulted in kernels...
Identification and management of glyphosate-resistant annual bluegrass (Poa annua L.)
(University of Missouri--Columbia, 2010)
bluegrass (hereafter referred to as CCMO1) in Columbia, Missouri survived an application of glyphosate following more than 10 years of continuous applications. Research was conducted in vitro to identify the extent of glyphosate-resistance in CCMO1...
Efficacy of oriental mustard (Brassica juncea L. Czern.) seed meal for weed and disease control in turf
(University of Missouri--Columbia, 2009)
Pest management in turf involves the use of fumigants such as methyl bromide, as well as selective pesticides. However, the loss of methyl bromide and development of disease resistance to fungicides suggests that more ...
Vegetation management along roadside and railroad right-of-ways
(University of Missouri--Columbia, 2018)
to restrict weed emergence. Field studies in central Illinois (three), Missouri (one), and Kansas (one) were established in 2015 and 2016 to compare fall single versus multiple application timings of residual herbicides from fall through the following summer...
Identification and characterization of glyphosate-resistant common ragweed
(University of Missouri--Columbia, 2007)
. With glyphosate's high efficacy rate and increased adoption over many hectares, it could be argued that where it is applied at least one or more times a cropping year, resistant weeds will occur frequently. In 2002, a Missouri population of common ragweed...
