Plain Language Analysis
“Prohibited noxious weed seeds” are defined in Wis. Admin. Code § ATCP 20.01(27) as the seeds of weeds that are highly destructive and are difficult to control by means of good cultural practices and the use of herbicides. Palmer amaranth and Waterhemp meet this definition, but neither are currently listed in the rule. Therefore, it is not currently a violation for these weed seeds to be distributed in seed mixes in Wisconsin. Adding Palmer amaranth and Waterhemp to the list of “Prohibited noxious weed seeds” in Wis. Admin. Code ch. ATCP 20 will prohibit the distribution of these weed seeds as part of pure seed or seed mixtures in Wisconsin.
Implementation of this rule will help protect Wisconsin’s cropland. Adjacent states, including Iowa, are facing the potential loss of thousands of acres of crop land traceable to the distribution of seed mixes that inadvertently included the cited weeds. If this rule is not enacted, Wisconsin potentially faces a similar fate.
Summary of Factual Data and Analytical Methodologies
Department program staff obtained information and data related to Palmer amaranth and Waterhemp from agriculture agencies in other states, including Minnesota and Iowa, both of which are currently experiencing the adverse effects of the introduction of those weed seeds.
Analysis and Supporting Documents used to Determine Effect on Small Business
Department staff consulted licensing information on file at the Department for seed labelers in Wisconsin, as well as information from the Wisconsin Crop Improvement Association (WCIA) and the Wisconsin Agribusiness Association (WABA), in order to identify stakeholders. The Department solicited feedback on the concept of prohibiting the inclusion of the two species within packaged seed that is labeled in Wisconsin. The stakeholders who were consulted expressed no opposition to the referenced additions to the prohibited weed seed list.
Business Impact
The Department expects the proposed rule to have minimal economic impact.
Environmental Impact
Prohibiting Palmer amaranth and Waterhemp will have a positive environmental impact in Wisconsin. This rule will assist in limiting the spread of weed seeds that have caused crop devastation in other states, including Iowa.
Federal and Surrounding State Programs
This rule proposal would update the Federal Seed Act (7 USC §§1511-1611), which governs the labeling of agricultural seed intended for interstate commerce. The list of State Noxious-Weed Seed Requirements Recognized in the Administration of the Federal Seed Act would be updated to reflect the changes instituted by the present rule.
Minnesota has listed Palmer amaranth as a prohibited noxious weed seed. Iowa has made Palmer amaranth a primary noxious weed in both seed and weed laws.
