This causes the buttercup to reflect light under your chin better than any other flower on the school sports field. Events Public engagement Jobs Give to Cambridge.

However, legumes such as clovers interseeded with grass pastures can be severely injured or killed by these herbicide products. For optimum results apply a herbicide in the early spring February - March before flowers are observed, when buttercup plants are still small and actively growing.

For best herbicide activity wait until daytime air temperatures is greater than 50 F for two to three consecutive days. Consult the herbicide label for further information on grazing restrictions, precautions, or other possible limitations. For fields heavily infested with buttercup a variety of control tactics may be needed. Apply a herbicide to help reduce the population of buttercup plants in the spring plus use good pasture management techniques throughout the year to help improve and thicken the stand of desirable forages.

Though a sea of yellow flowers sprawling across an open pasture may be a beautiful sight to onlookers, this plant can be a real management headache for pasture and hay fields.

To name a few reasons, buttercup is toxic to livestock, spreads aggressively, and is difficult to control. Buttercup is toxic to all species of livestock. The toxin protanemonin is released when the plant is chewed or otherwise wounded and is present in all parts of the plant. Animals that eat buttercup may suffer from blistering of the mouth and internal parts of the gastrointestinal tract, diarrhea, colic, and, in severe cases, death.

Fortunately, most animals will not eat buttercup because it is unpalatable. The toxin becomes inactivated when dried, so buttercup is not a concern in hay.
