Differential Tolerance of Cotton (Gossypiumsp.) Cultivars to the Herbicide Prometryn

Obtaining a Monoclonal Antibody against a Novel Prometryn-Like Hapten and Characterization of Its Selectivity for Triazine Herbicides

“…These residues accumulate in soil and water, posing a serious threat to biological diversity and human health [5]. For example, using prometryn in cotton fields often negatively impacts cotton growth and reduces production [6,7]. It was previously reported that the detection rate of prometryn in some waters was as high as 12.5%.…”

Protecting non-target plant species; suggested improvements to current pesticide registration guidelines

“…This study did not attempt to explain why the differences in herbicide sensitivity between cultivars or crop species were occurring. However, the idea that differences in the absorption, translocation, and metabolism of herbicide could be responsible for cultivar/species variation in regards to herbicide sensitivity has been investigated (Rowe et al, 1990;Burton et al, 1994;Bauer et al, 1995;Molin and Khan, 1996;Dayan et al, 1997). Environmental factors such as soil type and temperature, when coupled with the application of metribuzin, have also been shown to result in differences in yield among pepper cultivars (Schroeder, 1992).…”

“…For any given crop species, there are many different cultivars, some of which may exhibit varying levels of sensitivity to a particular herbicide. It is known that levels of herbicide tolerance differ among cultivars of various crop species; for example: corn (Keifer, 1989;Rowe et al, 1990;Burton et al, 1994), soybean (Wax et al, 1976;de Weese et al, 1989;Dayan et al, 1997;Hulting et al, 2001), potato (Graf and Ogg, 1976;Friesen and Wall, 1984;Aresenault and Ivany, 1996;Arsenault and Ivany, 2001), several kinds of beans (Bauer et al, 1995;Urwin et al, 1996), cotton (Abernathy et al, 1979;Molin and Khan, 1996), wheat (Bacon et al, 1986;Garcia-Baudin et al, 1990), peppers (Schroeder, 1992), pumpkins (Harrison and Keinath, 2003), cabbage (Hopen et al, 1993), collard and kale (Harrison et al, 1998), and peas (Jensen, 1993). This range in herbicide tolerance may result in an inaccurate representation of the phytotoxicity of the herbicide being tested depending on which cultivar is used during the registration process.…”

Nicosulfuron tolerance and population dynamics of woolly cupgrass (Eriochloa villosa)

“…Herbicide tolerance is the inherent ability of a species to survive and reproduce after herbicide treatment (WSSA 1998). When tolerance comparisons were made either among weeds or among weeds and crops, differences were typically attributed to absorption, translocation or metabolism (Cottingham and Hatzios 1992;Green et al 1992;Molin and Khan 1996;Risley and Oliver 1992). Herbicide tolerance sometimes involves more than one of the above mechanisms Since triazine-resistant common groundsel fSenecio vulgaris L.) was first discovered in 1968 by Ryan (1970), herbicide resistant weeds have received considerable attention.…”
