Atrazine 480
Trade Name
Active Ingredient atrazine

Rate per hectare (active) 1.01 to 1.49 kg/ha
Rate per hectare (product) 2.1 to 3.1 L/ha

Precautions

  • Apply PRE.
  • Weeds will normally emerge and die within a few days; atrazine can persist for varying lengths of time; longer under dry, cool weather and coarse textured soils. See tank-mixes for reducing rates and avoiding residues, and for treatments to provide annual grass control.
  • Can be tank-mixed with Gramoxone for PP burndown of emerged annual and perennial weeds, see Chapter 6, for more information.
