For management of:

Apron XL LS is a phenylamide fungicide that is used to control seed and soil borne diseases caused by fungi in the Oomycetes class, such as Pythium spp, Phytophthora spp. and certain downy mildews.

Pythium and Phytophthora Diseases:

  • Belong to the class Oomycetes.
  • Have the ability to "swim" in wet soil therefore can spread easily throughout a field.
  • Attacks many different crops, notably soybeans, coloured beans, pulse crops and alfalfa.
  • Responsible for damping off, seed rot, seedling rot, and root rots.
  • Found worldwide in all soil types.
  • Most damage done to seed and seedling but may also attack mature plants which results in a loss of vigour.
  • Attacks plants below soil surface but may spread to fruit and vegetables above the soil due to a "splashing affect" from rain.
  • Disease severity increases when crop grown for more than two consecutive years or grown in cool wet soils, as experienced during early planting, planting in poorly drained soils or no-till soils.
  • Decreases germination and emergence of seeds and seedlings.
  • Results in poor stands.
  • Only effective control is use of a systemic seed treatment fungicide.

For control of other soil-borne diseases, such as Rhizoctonia spp., Apron XL LS should be applied in combination with other registered fungicide seed treatments.

Application Information

Use Rates

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.

Application Method

Commercial Seed Treatment

Application Information

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.

Equipment Calibration

  1. Confirm "trip volume" (flow rate) of the liquid seed treatment through treater.
  2. Confirm "trip weight" of seed flow through treater.
  3. 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.

    Then:
    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
  4. Include as part of the total slurry volume, the recommended amount of seed treatment per 100 kg of seed.
  5. Confirm batch size to be treated and re-calculate total slurry volume.

Mixing Order

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.

Use Restrictions

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.”

Tank Mixes

This product does not contain a colourant. A suitable colourant must be added to the slurry prior to application to the seed. Follow instructions on the colorant package for mixing. Regulations pertaining to colouration of treated seed enforced under the "Seed Act" must be strictly adhered to when using this product. Users are responsible for ensuring that the treated seed, when dried and ready for bagging, has an unnatural colour.

Apron XL LS may be tank mixed with Maxim® 480FS for use in corn (field corn, sweet corn and popcorn).

Technical Information

Chemistry Group

Group 4 fungicide

Mode of Action

Metalaxyl-M, the active ingredient in Apron XL LS, is a phenylamide fungicide that is used to control seed and soil borne diseases caused by fungi in the Oomycetes class.

Apron XL LS is taken up very rapidly by the plant following seed germination and moves primarily acropetally (upward and outward) within the plant. This systemic movement protects new plant growth for several weeks.

Resistance Management

Experience has shown that strains of fungus resistant to metalaxyl-M and S-isomer may develop. Failure to control the disease will result in crop damage and/or yield losses. Since the occurrence of the resistance cannot be foreseen, Syngenta Canada Inc. accepts no responsibility for any loss of, or damage to, crops resulting from the failure of Apron XL LS to control the resistant fungus strains.

For resistance management, Apron XL LS contains a Group 4 fungicide. Any fungal population may contain individuals naturally resistant to Apron XL LS and other Group 4 fungicides. A gradual or total loss of pest control may occur over time if these fungicides are used repeatedly in the same fields. Other resistance mechanisms that are not linked to site of action but specific for individual chemicals, such as enhanced metabolism, may also exist.  Appropriate resistance management strategies should be followed.

 

To delay fungicide resistance:

Where possible, rotate the use of Apron XL LS or other Group 4 fungicides with different groups that control the same pathogens.

Avoid application of more than the maximum number listed in the label and consecutive sprays of Apron XL LS or other fungicides in the same group in a season.

Fungicide use should be based on an IPM program that includes scouting, historical information related to pesticide use and crop rotation and considers cultural, biological and other chemical control practices.

Monitor treated fungal populations for signs of resistance development. If disease continues to progress after treatment with this product, do not increase the use rate. Discontinue use of this product, and switch to another fungicide with a different target site of action, if available.

Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or IPM recommendations for specific crops and disease problems in your area.
