• Apply with groundboom equipment only. Do not apply using aerial application equipment.
• Laudis herbicide can be applied broadcast in a minimum of 100 litres of water per hectare (10 gal./ac.). For weed control in dense weed populations or under adverse growing conditions, 150 to 200 litres of water per hectare is recommended (15 to 20 gal./ac.). Good coverage is essential to achieve optimum weed control.
• Uniform, thorough spray coverage is important to achieve consistent weed control. Select nozzles and pressure that deliver medium spray droplets as indicated in nozzle manufacturer’s catalogues and in accordance with ASAE Standard S-572. Nozzles that deliver coarse spray droplets may be used to reduce spray drift provided spray volume per hectare (L of water/ha) is increased to maintain coverage of weeds.
• Flat fan nozzles of 80° or 110° are recommended for optimum post emergence coverage. Do not use nozzles that produce fine (e.g. cone) or extra coarse (e.g. flood jet) spray droplets.
• Typically, flat-fan nozzles operated at 200-400 kPa will deliver medium spray droplets, providing optimum spray coverage and canopy penetration. Lower pressure operation and/or higher volume flat fan nozzles typically deliver coarse sprays. Refer to nozzle manufacturer catalogues.
• Boom height should be based on the height of the crop – at least 33 centimeters above the crop canopy
• Air induction nozzles should be used at or near 550 kPa to produce a medium droplet size
• Proper agitation should be maintained within the tank to keep the product dispersed

¹ Includes ALS inhibitors (Group 2), Synthetic Auxin (Group 4); Photosystem II inhibitors (Group 5); EPSP synthase inhibitors (Group 9); PPO Inhibitors (Group 14) resistant biotypes

² For glyphosate-resistant biotypes use 220 mL/ha

³ Suppression only

⁴ Use higher rate within the labelled rate range of Laudis herbicide for weed control in dense weed populations or under adverse growing conditions

⁵ For improved control of Canada fleabane – field corn only: apply Laudis herbicide in tank mix with one of the dicamba-containing tank mix partners recommended on the label

⁶ For control of common groundsel (up to the 4 leaf stage) and improved control of volunteer canola apply Laudis herbicide at 220 mL/ha in tank mix with 500 mL/ha of Pardner herbicide

⁷ For improved control of volunteer canola and control of wild buckwheat: Laudis herbicide may be tank mixed with 1.2 L/ha of AAtrex^® Liquid 480 Herbicide. Maximum of one (1) application per season. Apply at the 2 to 5 leaf stage of field and sweet corn.

Application Tips

• For best results, apply to emerged, young, and actively growing weeds
• Do not apply more than 2 applications of Laudis herbicide to field corn or more than 1 application to sweet corn, per growing season
• Laudis is to be used in conjunction with a Methylated Seed Oil (MSO) based surfactant or Crop Oil Concentrate (COC) applied at 1% v/v, High Surfactant Oil Concentrate (HSOC) at 0.5-1% v/v or Hasten^TM Spray Adjuvant applied at 1.75 L/ha
• Use of a spray-grade liquid nitrogen fertilizer is recommended:
  • UAN (28%) at 3.5 L/ha or AMS at 1 kg/ha (99%) or 2 L/ha (49% solution) or 2.5 L/ha (40% solution)
• For ground application:
  • Boom height should be based on the height of the crop – at least 33 centimeters above the crop canopy
  • Apply in a minimum of 100 litres of water per hectare (10 gal./ac.). For weed control in dense weed populations or under adverse growing conditions, 150 to 200 litres of water per hectare (15 to 20 gal./ac.) is recommended.
• Restricted Entry Interval (REI) is 12 hours
• Pre-harvest interval: 45 days for grazing and harvested grain or forage
• If tank-mixing, always respect the maximum pre-harvest/grazing interval stated on the labels of all the tank-mix products.

Always read and follow label directions.

Water Volumes

Laudis herbicide can be applied broadcast in a minimum of 100L/ha (10 gal./ac.) of water. For weed control in dense weed populations or under adverse growing conditions, 150 to 200 L/ha (15 to 20 gal./ac.) of water is recommended. Good coverage is essential to achieve optimum weed control.

Resistance Management

Laudis herbicide contains an active ingredient from Group 27 which helps manage herbicide-resistant weeds. Laudis should be used as part of an integrated pest management system.

Mix Groups

Use tank mixtures with herbicides from a different Group when such use is permitted. To delay resistance, the less resistance-prone partner should control the target weed(s) as effectively as the more resistance-prone partner.

Herbicide use should be based on an integrated weed management program that includes scouting, historical information related to herbicide use and crop rotation, tillage (or other mechanical control methods), cultural (for example, higher crop seeding rates; precision fertilizer application method and timing that favors crop and not weeds), biological (weed-competitive crops or varieties) and other management practices. Weed size should also be considered, as the product is more effective on smaller weeds.

Monitor Weed Populations

After all herbicide applications check weeds in your fields for signs of resistance development (for example, one weed species on the herbicide label may not be controlled). If resistance is suspected, prevent weed seed production in the affected area if possible, by using an alternative herbicide from a different Group. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and always plant clean seed. Have suspected resistant weed seeds tested by a qualified laboratory to confirm resistance and identify alternative herbicide options.
