DECONTAMINATION AND DISPOSAL
For information on disposal of unused, unwanted product, contact the manufacturer or the provincial regulatory agency. Contact the manufacturer and the provincial regulatory agency in case of a spill, and for clean up of spills.

DIRECTIONS FOR USE
SHAKE WELL BEFORE USING.
Workers must wear coveralls over a long-sleeved shirt and long pants, and chemical-resistant gloves during mixing, loading, treating, clean-up, and repair.
For post-harvest treatment of commodities, apply using mechanical sprayer only.
A limit of 500,000 kg potato tubers may be treated per day per worker.
Clean all mixing and application equipment before using MERTECT SC Fungicide. Fill the mixing tank 3/4 full with water and begin mechanical agitation. Add the required amount of MERTECT SC Fungicide and fill the tank to the required level. Do not allow the suspension to stand without continuous agitation. If agitation is halted, stir and re-mix the fungicide suspension and resume agitation before using.

DOSAGE RATE - WHOLE POTATOES POST-HARVEST
For the post-harvest control of storage rots caused by Fusarium spp., Phoma spp., Helminthosporium spp., Oospora spp., and Rhizoctonia spp., prepare a suspension of 7.5 L of MERTECT SC Fungicide per 170 L of water. Spray 2 L of this suspension per metric tonne of potatoes. Potatoes must rotate along the conveyor line into storage to ensure complete coverage.

POME FRUIT (apples and pears)
For the control of Penicillium spp. and Botrytis cinerea on apple and pear fruit; dip, flood or spray the harvested fruit with a suspension of 0.5 L of MERTECT SC Fungicide in 500 L of water (a 500 ppm solution). Since the level of disease control in fruit is related to coverage of the fruit surface with the spray solution, the dip method of application is preferred. If using the spray application method, installation of additional spray nozzles at various locations along the conveyor belt may aid in improving spray coverage and hence disease control. The suspension is to be applied as a post-harvest dip or spray without waxing.
