ACETO SHIELD EC is an emulsifiable concentrate formulation of food grade chlorpropham for treatment of potatoes after store to inhibit sprouting. It is mixed with water and applied to potatoes in the packing line. A C E T O SHIELD EC inhibits sprouting by preventing cell division. Contact with the buds on the tuber is essential for results to be effective.

DO NOT APPLY IN THE FIELD.
DO NOT APPLY ON SEED POTATOES.

DIRECTIONS FOR USE
Potatoes must be clean and all bruises and cuts must have healed before treatment. Dirt on the potato may prevent the chemical from reaching the buds. Application before wounds have healed will prevent suberization and will leave the tuber open to infection by disease.
Normally a minimum of two weeks should elapse after harvest and before treatment.

APPLICATION EQUIPMENT
ACETO SHIELD EC is sprayed as a 1% emulsion to potatoes in the packing line. The spray nozzle should be set up in the packing line between the cleaning equipment and the packing equipment. In packing lines equipped with brushes, place the spray nozzle on the output side of the brushes. In wash lines, place the spray nozzle on the output side of the dryer rolls. Consult your Aceto Agricultural Chemicals Corp. representative for assistance in installing spray equipment.

MIXING DIRECTIONS
Prepare 10g/L solution by adding 1 litre of ACETO SHIELD EC to 34 litres of water. Form a uniform emulsion by stirring.

APPLICATION RATE

Apply 900 mL of the 1% emulsion per 20 bags of potatoes (45 kg per bag), or 25 litres per 25 tonnes.
