(1) A minimum of two phytosanitary field inspections of a trial ground must be conducted by the department. These inspections must take place at a minimum:

(a) During the seedling stage; and

(b) At the bloom stage.

(2) The phytosanitary field inspection application must include:

(a) A detailed varietal planting plan;

(b) A description of the exact location of the trial ground;

(c) For seed not treated with a fungicide that controls black leg disease, the manner in which the trial ground will be isolated from other known crucifer production;

(d) The distance by which the trial ground is isolated from other known crucifer production; and

(e) The method by which volunteers will be controlled in the following year.

(3) The person responsible for the trial ground must monitor the trial ground at a frequency of at least twice monthly. The responsible person must maintain records of these inspections and must make these records available to the department upon request.

If regulated diseases are identified, the responsible person must notify the department within twenty-four hours.

(4) If the field inspections by the department or the person responsible for the trial ground detect any suspect symptoms of regulated pathogens, and identification is confirmed by pathology testing, the trial ground is subject to destruction in whole or in part upon the order of the director.

(a) Infected plant residue must be promptly destroyed by chopping and incorporating it into the soil or by other means approved by the director.

(b) As a further precaution, the department recommends that, to the extent practical, crop residue be destroyed even when a regulated disease is not detected.

(c) The department will consult with pathologists, university personnel and appropriate subject matter experts in determining control measures and appropriate mitigation activities to prevent the spread of regulated diseases from the trial ground site. Such recommendations may be, but are not limited to, foliar applications of fungicides.

(5) A disinfectant must be applied to the:

(a) Machinery used in the production of the crucifer crop;

(b) Footwear of all persons entering the trial grounds; and

(6) The department will conduct at least one inspection of the trial ground location the following year to ensure control of volunteer crucifer plants has been achieved.
