The standard use rate of Apron XL LS depends upon the disease being controlled:
Pythium damping-off in wheat, barley*, oats*, rye*, grasses and soybeans: 20-40 mL per 100 kg of seed. Apply the higher rates when conditions are conducive to high disease pressure.
Pythium damping-off in lentils: 7 mL per 100 kg of seed
Phytophthora root rot in soybeans: 40 mL per 100 kg of seed
Downy mildew in sunflowers: 80 mL per 100 kg of seed
*Export use only.
See label for a complete list of diseases controlled and applicable use rates.
Commercial Seed Treatment
Apron XL LS is registered for use in commercial seed treating plants only. See the label for seed tag information that is required for seed treaters.
Apron XL LS is a liquid suspension formulation (LS) which, when mixed with water, forms a stable microemulsion.
Apron XL LS is designed to be mixed in water and applied through standard slurry or mist type commercial seed treatment equipment. To obtain optimum coverage, international experience suggests that a minimum slurry volume of 520-780 mL per 100 kg of seed (8-12 US fl oz per cwt) be applied to ensure good uniform coverage.
Apron XL LS should not be used in hopper-box, planter-box, slurry-box or other non-commercial seed treatment equipment.
Apron XL LS may be applied in a water based slurry with other seed treatment insecticides and fungicides approved for use on those crops on which Apron XL LS is registered. Apply through standard slurry or mist-type commercial seed treating equipment. Always conduct a jar test to confirm physical-chemical compatibility, before mixing different seed treatment products.
Apron XL LS is a colourless formulation. A suitable colourant must be added to the slurry mix prior to application to the seed. Follow instructions on the colourant package for proper mixing. According to the "Seeds Act", users are responsible for ensuring that the treated seed, when dried and ready for bagging, has been thoroughly stained with a conspicuous colour to show that the seed has been so treated.
Confirm "trip volume" (flow rate) of the liquid seed treatment through treater.
Confirm "trip weight" of seed flow through treater.
Calculate slurry volume applied per 100 kg of seed (see formula below):
Trip Volume (TV) = [Volume of Liquid Collected (mL)] ÷ [# of trips counted]
Trip Weight (TW) = [Weight of Seed Obtained (kg)] ÷ [# of trips counted]
Slurry Volume (SV) = [TV (mL) x 100 = mL per 100 kg seed] ÷ [TW (kg)]
Example: You have collected a total of 300 mL of liquid seed treatment at the end of 20 trips of the weighpan trip. Let us say that the corresponding weight of the seeds transported at the end of 20 trips is 100 kilograms.
Trip Volume (TV) = 300 mL ÷ 20 trips = 15 mL/trip
Trip Weight (TW) = 100 kg ÷ 20 trips = 5 kg/trip
Slurry Volume (SV) = [15 mL x 100] ÷ 5 kg = 300 mL/100 kg seeds
Include as part of the total slurry volume, the recommended amount of seed treatment per 100 kg of seed.
Confirm batch size to be treated and re-calculate total slurry volume.
Apply Apron XL LS as a water-based slurry utilizing standard slurry seed treatment equipment which provides uniform seed coverage. Uneven or incomplete seed coverage may not give the desired level of disease control. Thoroughly mix the recommended amount of Apron XL LS into the required amount of water for the slurry treater and dilution rate to be used. Follow the manufacturer’s application instructions for the seed treatment equipment being used. Maintain constant agitation of the slurry during the seed treatment process. Allow the seed to dry before bagging.
For treatment of seed for export, treater should verify actual registered rate in country of destination and/or use before exportation. Seed treated in accordance with the export use pattern must be labelled or tagged as follows: “FOR EXPORT ONLY - NOT FOR DOMESTIC SALE OR USE IN CANADA. This seed has been treated with APRON XL LS Fungicide which contains metalaxyl-M and S-isomer. Use chemical resistant gloves when handling treated seed. Do not use for food, feed or oil processing. Store away from food and feed.”
