General Info
Key Benefits
- Novel formulation facilitates rapid uptake of trinexapac-ethyl for improved performance with good rain fastness
- Early applications are less temperature sensitive than chlormequat
- Treatments at the beginning of stem extension reduce crop height and strengthen stems for reduced lodging risk

Application Information
Water volume
Apply STEMPER 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 and spraying
For use by tractor mounted/trailed sprayers only.
Half fill the spray tank with water and begin agitation. Add the required quantity of STEMPER. Add the remainder of the water and continue agitation until spraying is complete.
Spray tank cleaning
Thoroughly wash all spraying equipment and measuring equipment with water and a wetting agent using an integrated pressure rinsing device or manually rinsing three times immediately after use.
Restrictions
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.
- Crops should not be re-entered until spray residues are dry.
