Environmental effects of new herbicides for vegetation control in forestry

Fate and persistence of aquatic herbicides

“…Loss was mainly attributed to microbial breakdown. An 8 to 19 week persistence was observed in a review of glyphosate environmental fate (Ghassemi et al 1982).…”

Is site preparation necessary for bur oak receiving post-planting weed control?

“…Toutefois, la croissance était supérieure lorsque la préparation mécanique était combinée à l'application de l'herbicide simazine. La hauteur et le diamètre des plants de chênes étaient supérieurs avec l'utilisation de paillis de (von Althen, 1987;Cogliastro et al, 1990Cogliastro et al, , 1993Truax and Gagnon, 1993 (Frochot and Levy, 1980;Davies, 1988;Marineau, 1992;Cogliastro et al, 1993;Truax and Gagnon, 1993 (Ghassemi et al, 1982). (Rowe, 1972 (Bouchard et al, 1985), including geomorphology and land-use patterns, guided the selection of an experimental site which is typical of the zones with underused forestry potential.…”

Weeds in Forestry and Possibilities of Their Control

“…Single applications of forestry herbicides at stand initiation have minor and temporary impacts on plant communities and wildlife habitat conditions . Studies carried out on the effect of herbicides hexazinone fosamine ammonium and glyphosate in forestry have revealed that these herbicides have minimal effects on soil microorganisms and exhibit little or no potential for bioaccumulation (Ghassemi et al, 1982). If herbicides are properly used, current research indicates that the negative effects on wildlife usually are short-term and that herbicides can be used to meet wildlife habitat objectives (Wagner et al, 2004).…”
