2,4-D; Festuca arundinacea subsp. arundinacea; application timing; crude protein; developmental stages; dicamba; dormancy; field experimentation; forage yield; hay; metsulfuron; nutritive value; pastures; pesticide application; picloram; spring; summer; weeds
Abstract:
... Field trials were conducted in 2009 and 2010 to investigate the effects of metsulfuron-containing herbicides on tall fescue growth, seedhead production, yield, and forage nutritive value. Several rates of metsulfuron-containing products and picloram plus 2,4-D were applied to a weed-free tall fescue hay field in the early spring vegetative, late spring boot, and late summer dormancy stages of grow ...

Abstract:
... Separate field trials were conducted in 2007 and 2008 to investigate the effects of increasing densities of common ragweed or common cocklebur on total yield and forage nutritive values in tall fescue pastures. Common ragweed densities ranged from 0 to 188 plants m⁻⁻², and common cocklebur densities ranged from 0 to 134 plants m⁻⁻². Total biomass yields (weeds plus tall fescue) were determined in ...
