Crop Cautions
Avoid spray drift onto neighbouring crops.
Only use on crops at risk of lodging.
Do not apply if rain or frost is expected or if the crop is wet.
Do not spray crops under stress or to crops suffering from water logging, pest attack, disease or frost.
Take particular care to avoid overlapping of sprayed strips.
Treatment may lead to cereal ears remaining erect through to harvest.
MIXING AND APPLICATION
For use by tractor mounted/trailed sprayers only.
Water volume
Apply OPTIMUS in 200-400 L/ha water. The higher water volume may be used if the crop is dense and increased penetration of spray is required. Apply as a MEDIUM (BCPC definition) quality spray.
Mixing
Half-fill the spray tank with water and begin agitation. Add the required quantity of OPTIMUS. Add the remainder of the water and continue agitation until spraying is complete.
