Buttercups in Pastures and Hayfields
A field full of dainty, bright yellow buttercups may look pretty, but those tiny flowers pose a threat to horses. When ingested, the leaves and stems of buttercups release a toxic oil called protoanemonin, which can cause excessive salivation, mouth blisters, diarrhea and mild colic.21 мая 2012 г.
Buttercups can cause mouth pain and blisters, drooling, oral and gastric ulcers, colic, and diarrhea. Horses are one of the most sensitive species to Ranunculus’ gastrointestinal effects. These effects can be severe if horses ingest buttercups in large quantities, but their acrid taste usually deters further grazing.
Dig or grub out daisies from lawns using an old kitchen knife or a spike-like daisy grubber. Alternatively, slash though the mats of foliage with a knife at weekly intervals to weaken and loosen the plants. Collect mowings from the lawn, as this can help spread daisies. Pull or dig out daisies in borders by hand.
Fertilizer and lime doesn’t kill the broomsedge, but instead creates an environment that is more favorable to desirable grasses such as tall fescue and orchardgrass. Grazing management is another component of controlling broomsedge in pastures.

The plants contain the chemical ranunculin, which, when crushed or chewed, becomes the toxin protoanemonin. Protoanemonin is a bitter-tasting oil that irritates the mucous membranes of the gastrointestinal tract, and is poisonous to horses, cats, and dogs. The flower part contains the highest amount of toxin.
If you have only a small patch of creeping buttercup, you might be able to kill it with vinegar before it spreads. To do this in an area where other plants are growing, use a spray guard such as the one in “How to Spray Weeds and Insects Without Killing Everything Else.”
Roundup is the winner except care needs to be taken, as it’s not a selective weed killer, so will also kill the grass. The horses only need to be kept off the grass until the roundup has dried for their own safety, or a bit longer to ensure the weeds are killed.
