Guthion Label Change

Farmers Urge Congress to Keep COOL

New Label Approved for Guthion

From: The Vegetable Growers News, Sparta, MI

Aug. 28, 2003 - In the continued phase-out of Guthion (azinphos-methyl), the Environmental Protection Agency (EPA) has approved a new label for the product effective Aug. 21.

The new label contains changes in crop uses as follows: Guthion is no longer available for use on alfalfa, beans, birdsfoot trefoil, broccoli, cabbage, cauliflower, celery, citrus, clover, cucumbers, eggplant, filberts, grapes, melons, onions, pecans, peppers, plums and dried prunes, quince, spinach, strawberries and tomatoes.

Guthion remains until 2005 for caneberries, cotton, cranberries, nectarines, peaches, potatoes and southern pines seed orchards. Guthion remains for almonds, apples and crabapples, blueberries, brussels sprouts, cherries, nursery stock, parsley, pears, pistachios and walnuts.

With this action, Guthion Solupak will be the only formulation supported by Bayer CropScience. All crop uses formerly on Guthion 2L exclusively have been transferred over to the Guthion Solupak label.

In addition to spray drift language changes, the newly approved label reflects previously agreed upon changes in buffer zones, use in u-pick situations, lower use rates, etc. Review the new label for specifications about particular usage patterns.
