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.
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.
