ABSTRACT
BACKGROUND: The readability of restricted-use pesticide labels is an important element in preventing misuse and unsafe application practices. METHODS: An optometric analysis of 54 pesticide labels was conducted to determine the visual acuity required to read the average general use label. Additionally, a survey of 1623 Wyoming residents was conducted to determine the extent label directions are read, understood, and adhered to. RESULTS: A visual acuity of 20/30 and 20/40 is required to read the average general use and restricted use pesticide label, respectively. The mean and mode cognitive reading level required is the 11th grade. About half of the sample population read the label and two thirds reported always following label directions. CONCLUSIONS: A significant proportion of the American public can not or does not read or understand pesticide labels and does not follow the label instructions. Essential pesticide use and safety information is not being effectively communicated to the public.
