Crops Treated and Time of Applications
1. Winter wheat
Apply 0.4 litres/ha between the leaf sheath erect stage (GS 30) and before flag leaf sheath extending stage (GS 41).
2. Winter barley
Apply 0.4 litres/ha between the leaf sheath erect stage (GS 30) and the second node detectable stage (GS 32) or 0.6 litres/ha between the flag leaf just visible stage (GS 37) and before flag leaf sheath extending stage (GS 41).
3. Spring barley
Apply 0.5 litres/ha between the leaf sheath erect stage (GS 30) and the second node detectable stage (GS 32).
4. Winter and spring oats
Apply 0.4 litres/ha between the leaf sheath erect stage (GS 30) and the first node detectable stage (GS 31).
5. Rye, Triticale, Durum wheat
Apply 0.4 litres/ha between the leaf sheath erect stage (GS 30) and the second node detectable stage (GS 32).
6. Ryegrass (seed crops)
Apply 0.8 litres/ha between the leaf sheath erect stage (GS 30) and the first node detectable stage (GS 31).
Water Volumes
Apply FREEZE in 200- 400 litres water/ha. Increase the volume of water in dense crop stands if necessary, to improve penetration.
Mixing and Spraying
Charge the sprayer with half the required volume of water and begin agitation. Add the correct quantity of FREEZE to the tank. Complete the filling with the rest of the water, and maintain agitation until spraying is completed. Apply without delay on the day of mixing. Do not allow the spray mixture to stand without agitation. Apply as a ‘medium’ spray (BCPC definition) at a pressure of 2-3 bar. Take particular care not to overlap spray swaths. Wash all spraying equipment thoroughly after use using water and a suitable detergent or wetter.
