Procedures: Regulatory Treatment and Certification Sanitation and Treatment Sanitation Various sanitation procedures must be followed from the time a field is identified as infested with golden nematode until the field is officially surveyed and confirmed negative for golden nematode to prevent the spread of the pest. Procedures deemed appropriate by the officer will be implemented following each authorized activity on an infested field. See Sanitation on page 2-3-3 and . Authorized Pesticides Steam heat treatment is the established method of fumigating regulated articles. See T.406C & T.406D in the PPQ Treatment Manual. Methyl bromide is authorized for treatment of regulated articles for golden nematode. See Figure 3-1-1. Dosage 15 lb. per 1,000 square feet (ft.) 128 (g/m 3 ) (8 lb./1000 ft. 3 ) (grams/m 3 = oz./1000 ft. 3 ) Temperature and Exposure Time 24 hours (hr.) @ 15.5° C (60° F) or above 48 hours (hr.) @ 15.5° C (60° F) or above Reading 180 grams (g) ounce (oz.) minimum concentration reading at 1/2 hour 120 grams (g) ounce (oz.) minimum concentration reading at 24 hours 100 g oz. minimum concentration reading at 1/2 hour 75 g oz. minimum concentration reading at 24 hours 50 g oz. minimum concentration reading at 48 hours FIGURE 3-1-1 Methyl Bromide Fumigation at Normal Atmospheric Pressure (NAP) Certification Period Once the infested field is treated, the certification period lasts as long the treated area is protected from recontamination. 3-1-20 Golden Nematode Program Manual 07/2008-01 PPQ
Procedures: Regulatory Treatment and Certification Approved Treatments Approved Treatments Irish Potatoes, Grade A or Grade B (Except Seed Potatoes) Potatoes must be washed, brushed, or flumed to remove soil. Grade A or B Irish potatoes from golden nematode infested fields cannot be moved without certification. When Grade A or Grade B Irish Potatoes (except seed potatoes) meet the requirements below, the potatoes may be moved from golden nematode-regulated (but not golden nematode infested) areas without certification: 1. Fields that have received two years of a resistant variety treatment, followed by a negative post-treatment survey before the fields are replanted to potatoes. 2. Subsequent production from such fields would move as described below: A. Potatoes will be free of soil, including soil clods, soil clumps, soil peds, aggregates, etc. B. Shipping container will be free of soil. 3. Subsequent potato production from formerly-infested fields which have undergone successful resistant-variety treatment verified by intensive negative survey may move in accordance with procedures described above. See Survey to Release Land from Exposed Status on page 2-3-12. 4. Resistant varieties grown as a control treatment on infested fields must be graded and cleaned under the observation of an officer who will permit the movement of these potatoes when cleaned to the officer’s satisfaction, and transported for consumption in approved containers (see Approved Containers and Equipment on page 3-1-17). In some instances, satisfactory cleaning may require washing, grading, and/or fluming. 07/2008-01 Golden Nematode Program Manual 3-1-21 PPQ
