The EPA has granted a crisis exemption Section 18 for Gramoxone Extra for preharvest application in dry and green field pea.
Some weeds controlled are lambsquarter, nightshade, mustard, pigweed and mayweed.
The above-normal rainfall in many parts caused ideal weed growth and warrented the Section 18. Gramoxone Extra as a dessicant will burn down weeds and speed harvesting operations. A maximum of 3,000 acres may be treated. EPA has been approached to extend the use of Gramoxone Extra beyond the crisis exemption's Aug. 4 expiration date. A series of chemical and DNA tests confirm the weed are resistant to Roundup, Liberty and Pursuit chemicals.
