Nothing in these weed sheets should be interpreted as superseding pesticide laws or the LABEL on a pesticide product. The LABEL is a legal document describing the proper and allowable use of a pesticide product. ALWAYS READ THE LABEL to determine the requirements for a product's use, and whether it may be used in a particular location or situation.

The weed sheets were developed by reviewing the scientific and trade literature. The information in them was reviewed by a weed scientist and by persons actively managing these plants in the field. The information in the sheets is correct to the best of our knowledge but may not apply in every situation. For some of the weed species, available information is limited.
