Change in Pre-Harvest Interval for Dual Herbicide on Spinach, Reminder on Waiver

Gordon Johnson, Extension Vegetable & Fruit Specialist; gcjohn@udel.edu

The pre-harvest interval for Dual Magnum on spinach has been changed from 40 to 50 days. Growers are reminded that a Special Local-Needs Label 24(c) has been approved for the use of Dual Magnum 7.62E to control weeds in spinach in Delaware, Maryland, New Jersey, Pennsylvania, and Virginia. The use of this product is legal ONLY if a waiver of liability provided by the local growers association has been signed by the grower, all fees have been paid, and a label has been provided by the association.

In Delaware, the Fruit and Vegetable Growers Association of Delaware is the entity that holds these labels and waiver forms. Contact Gordon Johnson, Extension Vegetable and Fruit Specialist, University of Delaware, for waiver forms and copies of the revised label:
