3. Biological -The use of organisms such as sheep, goats, cattle, insects and plant diseases to disrupt the growth of undesirable plants. 4. Chemical -The use of herbicides of plant regulators to disrupt the growth of undesirable pleats. Pick one type of control method for each weed species that is on the property. This is what you will be implementing on a regular basis. Be sure it can be carried out. However, if the weed infested sites occur in different habitat types such as; pasture, riparian area, wetlands, etc. pick one type of control method for each area. Be sure to indicate where the methods will be used. Try to include the grass species that will be used, if reseeded and the chemicals that will be applied. Weed management of noxious weeds in range, pasture and non-crop sites is as follows: Canada Thistle A. Mechanical and Chemical Control -Mowing will occur throughout the growing season in order to keep the plants from going to seed. Mowing will be teaninated is late August followed by a herbicide treatment during late September through October - before a hard frost. B. Guttural and Chemical Control -Use of a short residual herbicide followed by a seeding with a competitive grass such as western wheatgrass or other sod forming species (indicate species). C. Chemical Control Only - A herbicide application will be applied from rosette to bud stage. This will be followed up with a fall application, if needed. The herbicides that can be used independently or is combination with other herbicides on Canada thistle include: Curtail, Redeem R&cP, Clarity, Tordoa 22K, 2,4D, Telar and Roundup Pro. You must read the label and use a herbicide labeled for the intended site. Musk sad Scotch Thistle A. Mechanical and Chemical Control -Mowing will occur several times throughout the summer, but no later than the bud stage of the thistle plants. This will keep the plants from going to seed. A herbicide will be applied in the fall, before a hard frost, on the new rosettes and any giants that have bolted. B. Mechanical Contra! Only - Multiple mowings will be conducted throughout the summer to keep the plants from going to seed. Potentially two to four times during the growing season. C. Chemical Control Oaiv - A herbicide will be used in the spring and fall when the plant is in the rosette stage. The herbicides that can be used independently or in combination with other herbicides on musk and Scotch thistle include: Curtail, Redeem R&P, Clarity, Tordon 22k, Telar, Escort, Roundup Pro and 2,4D. You must read the label and use a herbicide labeled for the intended site.
