When is the optimum timing for Arylex?

Arylex based products will work in all weather conditions though weed death may be slow under very cold conditions. Control is influenced by weed size with smaller stages of weeds more easily controlled. However, unlike herbicides the activity of Arylex on target weeds is not significantly influenced by temperature. This means that control can be achieved under cold (inactive periods of weed growth) and warm conditions with active growth.
