Goatweed ( Scoparia dulcis), also referred to as sweet broom and licorice weed, is a perennial plant that is becoming a serious problem in pastures. A problematic weed in citrus groves for many years, goatweed now appears to be proliferating in improved pastures as the calls for its identification and control have increased greatly over the past couple of years. The spread of goatweed in Florida can be attributed to a number of things including prolific seed production, movement of seeds from citrus groves to pastures through mowing equipment or wildlife, and the tolerance of goatweed to several herbicides utilized in citrus groves and pastures. Goatweed is particularly dense in areas that have been overgrazed or previously harvested for sod.

Mexican prickly poppy (Argemone mexicana), also known as goatweed, Mexican thistle, prickly poppy, and yellow thistle, is a member of the poppy family.

Coral ardisia, also known as coral berry, spice berry, and scratchthroat, was introduced to Florida in the early 1900's for ornamental purposes. Since then, it has escaped cultivation, and it is found in hardwood hammocks and other moist, natural-wooded areas and grazing lands. Although there is no published literature supporting the theory that coral ardisia is toxic, it is suspected that the berries and/or foliage are poisonous to livestock, pets, and humans.

The progression of trees and other woody plants into pastures, fencerows, ditch banks, rights-of-way and other areas is a common occurrence. These woody species can be particularly troublesome and require control since they will compromise fence intregrity, impede canal drainage, interfere with transmission of electricity, and some species (such as cherry trees) are highly poisonous to livestock. The aim of this publication is to detail the techniques for the removal of woody plants.
