10th May 2002:Site was pegged and sprayed with Spray.Seed® 2 L/ha to kill a background population of 3 to 4 leaf ryegrass that had germinated on a previous rainfall. 14th May 2002 Sprayed all treatments using the Department of Agriculture boom spray. The boom spray was set up to apply 50 L water /ha at 12 kph, through 02 (blue) nozzles. Ryegrass was at the half leaf stage, approximately 240 plants /m2. Spray conditions were extremely overcast (ie. no sun visible), winds 5/8 km/h decreasing towards nightfall. Glyphosate treatments were applied from 2pm. Spray.Seed® treatments were applied from 5pm onwards. |
