EPA conducted a re-registration review of mancozeb along with the FQPA assessment. As a result of that review, mancozeb registrants were advised that the continued registration of five current uses will require substantial data. These uses are residential turf, foliar application to cotton, pineapple propagation, athletic fields, and pachysandra.
In a June 1, 2005 Federal Register Notice, EPA announced that each of the mancozeb registrants voluntarily advised EPA that they (the registrants) would not support the continued use of mancozeb on residential turf, foliar application to cotton, or the pineapple propagation treatment. A similar notice regarding athletic fields and pachysandra was published on November 2, 2005.
Why Withdraw these Uses?
- Mancozeb is currently seldom-used for disease control in these areas –
- For disease control on home lawns, athletic fields, and pachysandra – other disease management tools have replaced this use;
- For disease control on cotton – mancozeb is registered only for rust control on cotton in the Southwest United States, and rust does not occur frequently;
- For one method of pineapple propagation treatment – which involves dipping the plant material in the fungicide solution prior to planting.
- Supporting these uses would have required EPA and Task Force Members to expend resources on little-used treatments.
Each of the Task Force members independently determined that support of these uses was not economically justified so all registrants voluntarily withdrew the uses. Actions such as this are quite common during reregistration activities. The mancozeb registrants continue to support use on sod farms, seed farms, golf courses, and industrial and commercial lawns. All of the other crops will remain on the label.
