# Handy Hints When Using Passtox® Clear

• Allow a minimum 24 hours before irrigation or likelihood of any rain to ensure that the spray will be absorbed into the weed.
• Avoid spraying in very hot conditions (above 30°C), as inadequate absorption by weeds will occur. Also this product may be ineffective below 21°C
• The timing of sprays can be crucial. Weeds are always best sprayed when they are young; at this stage they are most susceptible to herbicides. As weeds age they are increasingly difficult to control, as well as possibly leaving unsightly marks on turf.

DO NOT use on Kikuyu, Queensland Blue Couch, Carpet or Centipede grass as injury will occur.
