ATCP 21.15(4) (4) Enforcement.

ATCP 21.15(4)(a) (a) The department may issue pest quarantine and abatement orders under ss. 94.01 and 94.02, Stats., and s. ATCP 21.03, to prevent or control late blight infestations, or to remedy violations of this section.

ATCP 21.15(4)(b) (b) If the department finds any field infested with late blight, the department may order the person owning or controlling that field to treat it, in a manner specified by the department, in order to control or eliminate the infestation. Treatment may include pesticide applications specified by the department.

ATCP 21.15(4)(c) (c) The department may order the destruction of a potato crop infested with late blight if the department finds that alternative measures will not adequately prevent or mitigate the spread of late blight.

ATCP 21.15(4)(d) (d) The department may seek to prosecute violations of this section under s. 94.77, Stats.

ATCP 21.15 Note Note: The University of Wisconsin-Extension plant pathology and horticulture departments have developed integrated pest management procedures (IPM) that help protect against late blight. Growers are urged to follow these IPM procedures. IPM procedures and late blight forecasting information are available from the UW-extension county agricultural agent, or through a UW-extension computer program called the potato disease management plan under WISDOM.
