Express® PRO was developed specifically for Western Canadian growers and applicators who demand professional strength control of the toughest broadleaf weeds – ones that often escape glyphosate alone. Using Express PRO as an add-in with your glyphosate brings 2 active ingredients to provide a powerful second mode of action for effective resistance management with up to 15 days of extended broadleaf weeds like cleavers, dandelion, narrow-leaved hawksbeard and volunteer canola. By choosing Express PRO, growers select pre-seed weed control to fit their key weed targets, agronomic requirements and cropping plans.

Aim-Express PRO


Post Harvest Information Sheet






Adding Express® PRO herbicide to your glyphosate burn-down delivers up to 15 days of extended control on key broadleaf weeds like cleavers, dandelion, narrow-leaved hawk’s-beard and volunteer canola (excluding Clearfield® varieties).

Chemical Group: Group 2. Registered and Supported Tank Mixes: Express® PRO herbicide must be tank-mixed with glyphosate. Timing: Wait a minimum of 24 hours after the application of Express® PRO herbicide and glyphosate before planting wheat (spring, durum, winter) or barley. Note: Do not use on highly variable soils that have gravely or sandy areas, eroded knolls or calcium deposits. Heavy rainfall soon after application may result in visual crop injury or possible yield reduction. Conditions such as thin crop stand, sandy soil or low soil organic matter may increase the severity of injury.   Chemfallow: Allow at least 10 days after treatment before tillage. Post-harvest: Apply to fields where wheat, barley or oats will be seeded next spring. Note: Limit of one (1) application of metsulfuron products per growing season.   Crop Rotation:

Twenty-four (24) hours: Wheat (spring, durum and winter) and spring barley.

Ten (10) months: Canola, peas, faba beans, field corn, soybeans and flax. Oats may be seeded anytime in the following season.

Twenty-two (22) months: Lentils.

Application Information: Rates and Packaging: 7 g/ac. One (1) jug treats 80 acres. Water Volume: 22 L/ac (5 imp. g/L). Mixing Instructions:

  1. Start with a clean empty sprayer. Ensure sprayer is equipped with 50 mesh screens or filters.
  2. Fill sprayer tank 1/2 full with clean water.
  3. With agitator running, add the FMC products according to their formulation as shown below in the WAMLEGS chart. Add the products slowly. Ensure agitation reaches all parts of the tank.
  4. If using a mix & fill tank, add the FMC product to as large a volume of water as possible in a chemical handler.
  5. Add product to tank and agitate for 10 minutes
  6. Proceed with adding additional products as per the WAMLEGS chart and water while maintaining agitation. Ensure each product is agitated sufficiently, before proceeding to the next tank mix partner.
  7. For repeat tank loads, start off with an empty tank or ensure spray solution is reduced to 10% or less, of the original volume.
  8. (Recommended) For the last load of the day, add 10 L of household ammonia (containing at least 3% ammonia) to the tank heel PRIOR to the addition of the FMC product, water and glyphosate. Follow steps 2 through 6.
  9. (Recommended) When spraying an FMC product, for multiple days in a row it is important, at the end of each day to fill the sprayer with water, overnight, to prevent any film from developing on the tank walls.

Wettable powders, dispersible granules, soluble granules (WG, DF, SG, WP, SP)

Complete filling the spray tank to the desired level

Special mixing instructions for soluble granule (SG) herbicides when using a CHEM HANDLER:

  1. Ensure the chem handler is clean (rinsed with ammonia).
  2. For best results, add the SG herbicide to the top of the sprayer tank.
  3. If you do use a chem handler, make sure that all of the SG herbicide is completely dissolved and injected into the main tank with agitation, before adding other chemicals.
  4. Low water volumes in some chem handlers can cause the water to become saturated with soluble granules, leaving undissolved granules. In that case, rinse the chem handler with clean water before adding any other chemicals.
  5. Always dissolve the soluble granules with agitation in the main tank before adding a tank-mix partner.

Note: Follow the clean-out procedure recommended for sprayer tanks for the chem handler.
