### § 74-03-13-03. Field standards.

1. Isolation. Prior to inspection, a field must be isolated from inseparable crops by a fence row,
natural boundary, or by a strip of at least five feet [1.52 meters] wide which is either mowed,
sprayed, or uncropped.
2. Specific field standards.
Maximum Tolerance

Other varieties or classes * .01 percent 0.05 percent 0.1 percent
Inseparable other crops none none none
Prohibited noxious weeds ** none none none
Objectionable weeds *** none none none
Bacterial bean blights + .01 percent .05 percent .1 percent
Anthracnose none none none
Wilt none none none
Common bean mosaic none 0.5 percent 1.0 percent
*Other varieties shall not include variants characteristic of the variety.
**Prohibited noxious weeds include only field bindweed, leafy spurge, yellow starthistle, and Russian knapweed.
The tolerance for prohibited or objectionable weeds, or both, will be determined by the inspector.
***Objectionable weeds include nightshade species and cocklebur.
+ 1. The grower shall isolate and not harvest within a one hundred-foot [30.5-meter] radius of all staked

(flagged) plants. A grower must leave in place any stakes or flags by plants with blight-infected pods. The
inspector may recheck the field to ensure that these blighted areas were not harvested. Failure to leave
the rejected area will result in total field being rejected.
2. Areas to be isolated must be mapped out on field inspection report.

alyssum, horsenettle, quackgrass, wild oats, wild vetch species, giant foxtail, wild radish, nightshade species,
and cocklebur.
***The grower is responsible for having a bacterial blight test and anthracnose test, performed by a seed
department-approved laboratory, on the harvested seed of each field of dry field beans. If seed from more
than one field is commingled prior to testing, a bacterial blight test and anthracnose test must be performed on
each separate seed lot. Lot size is restricted to two thousand bushels.
A seed treatment to reduce surface bacterial contamination of the seed coat is recommended.
