Annual weeds may be sprayed anytime they are activley growing. Use the lower rate on weeds up to 15cm tall; increase to the higher rate where weeds are over 15cm tall.
Visible symptoms develop in 3-7 days but complete desiccation may take 20-30 days under cool conditions. Apparent Glyphosate 360 Herbicide does not provide residual weed contol. Repeat treatments may be necessary to contol later germiniating weeds.
For residual control of annual weeds, Apparent Gluphosate 360 Herbicide may be tank mixed with Simazine or Altrazine flowable formulations.
