1Generation 1and 2 seed lots exceeding specified blackleg tolerances shall be downgraded to the next appropriate generation level. Roguing of these lots to restore them to blackleg tolerance will not be allowed.

Inspection Policy: Applicants of Generations 1through 3 seed lots may be given one additional opportunity to restore the seed lot to tolerance following the first and second scheduled inspections providing the following conditions are met:

  1. The applicant agrees to complete roguing of the field as soon as possible and
  2. Field conditions, plant development and other factors such as presence of insect vectors would not in the opinion of the inspector limit the accuracy and effectiveness of the roguing effort.

PVX (Lab Test): Will be performed on G1 through G3 seed lots with tolerances for G1=0 and G2=1.0. G1and G2 lots exceeding the PVX tolerances will be downgraded to the next appropriate generation level.

2At the applicant's option, Generations 4-6 seed lots may be tested for PVX and/or PVS. The Department will be notified at the time of application. Sampling procedures will be those used for Generation 3. PVX content of the tested lots may be listed on the label or bulk certificate at the applicant's option. Tolerances do not apply
