Abstract/Contents:"Preharvest application of 1 and 2 litres ha-1 IPA glyphosate (glyphosate) to a seed crop of S24 perennial ryegrass with moisture concentrations of around 400 and 340 g kg-1 (40 and 34% moisture content w/w) failed to significantly lower seed and straw moisture concentration at harvest and consequently did not affect combine rate. Addition of extra surfactants and ammonium sulfate to glyphosate did not significantly increase the rate of desiccation. The quality of harvested seed was impaired at both rates and application times. Germination was significantly lowered through the production of abnormal seedlings. The germination of seed harvested in the previous year from glyphosate-treated plots decreased with storage. Seed vigor, germination rate and field emergence were also significantly decreased as a result of glyphosate application. The effect of glyphosate on seed quality precludes its preharvest use as a desiccant in the ryegrass seed crop. Harvesting difficulties due to the production of secondary vegetative tillers may be overcome by swathing rather than direct combining."
