The EPA?EUR??,,????'?????<????????????EUR??,,??s Web site now has enhanced information about pesticides in the pyrethrin/pyrethroid class of insecticides. These include a new consolidated Web page on these chemicals; a paper and related fact sheet on the agency?EUR??,,????'?????<????????????EUR??,,??s analysis of whether an association exists between pyrethrin/ pyrethroid exposure and asthma and allergies; and a description of new environmental hazard and general labeling for non-agricultural outdoor use of pyrethroid products, including tips for consumers to use in reducing the potential for pesticide runoff and drift.
Pyrethrins are commonly used on golf courses and are labeled for a number of insect pests found on golf courses. One of the most important target insect pests is annual bluegrass weevils. Pyrethrins are applied using a boom sprayer, or if a granular formulation, applied using a drop spreader or a rotary spreader.
The use of pyrethrins and pyrethroids has increased during the past decade with the declining use of organophosphate pesticides. This new Web site is available at www.epa.gov/oppsrrd1/reevaluation/pyrethroids-pyrethrins.html.
Included on this Web site is a new paper on pyrethrin/pyrethroid products and asthma/allergy effects. Differing from previous reviews, this review uses a ?EUR??,,????'?????<????????weight of the evidence approach?EUR??,,????'?????<???????? to determine whether there is a clear and consistent association between pyrethrins/pyrethroid exposure and asthma and allergies. From this analysis, the Agency has concluded that there is no clear evidence of an association. For more information on this paper, visit www.epa.gov/oppsrrd1/reevaluation/paw-factsheet.html.
Also included on the new Web site is a page on Environmental Hazard and General Labeling for Pyrethroid Non-Agricultural Outdoor Products. This page describes the revised ?EUR??,,????'?????<????????Environmental Hazard Statements?EUR??,,????'?????<???????? and general ?EUR??,,????'?????<????????Directions for Use?EUR??,,????'?????<???????? language for pyrethroid pesticide products used in non-agricultural outdoor settings, which affects over 2,000 end-use pyrethroid pesticides. The revised label language will reduce the potential for pesticide runoff and drift of pyrethroid pesticides. Consumers can begin using these improved practices to protect water resources.
