Integrated weed management (IWM) considers the overall management of a weed species with the objective of preventing the establishment of the weed from ever occurring, to prevent the spread or to minimize the impact. IWM relies on the combination of a variety of methods such as chemical, biological, mechanical, and cultural controls as well as overall preventative measures. Using IWM creates an opportunity to use herbicides more selectively, which reduces the impact on the environment as well as slow the development of weed resistance to herbicides.
Good pasture management will help prevent tall buttercup. Promote healthy grass by fertilizing and not overgrazing. Use grass and forage seed that has a “Certificate of Analysis” declaring it free of tall buttercup seed. Use hay that is free of tall buttercup. Clean mowers and other equipment to avoid spreading tall buttercup seed into uninfested areas.
Hand picking or digging up the entire plant, including the roots, before seed maturation will successfully eliminate the plant, but this practice is most effective for small infestations of Tall Buttercup.
Tall buttercup prefers wet soil so improving soil drainage will also discourage plant establishment.
Maintaining a vigorous grass stand in pasture and rangeland will provide good competition and help control tall buttercup and reduce the likelihood of an invasion.
Properly managed pastures where a competitive forage stand is maintained using fertilization will help control tall buttercup, but in poorly managed pastures, tall buttercup will use any nutrients that are added.
Tall buttercup will not survive cultivation so plowing and re-seeding to an annual crop for several years may reduce infestations.
Mowing prior to seed set can assist in reducing infestations. Mowing must be timely to prevent further spread of the seed.
Tall buttercup is toxic to domestic animals and wildlife therefore grazing is not a recommended practice for control of tall buttercup. Good grazing management that maintains a competitive and healthy grass stand will assist in preventing establishment of tall buttercup within the field.
