Complete use directions to ensure that foliar application will be effective and useful for each recommended purpose, under Wisconsin conditions. Use directions shall identify recommended application sites, rates, frequency, timing, and methods.(b) Paragraph (a) does not apply if the foliar fertilizer label includes all of the following that apply: 1. The following clear and conspicuous written statement if the fertilizer label guarantees primary plant nutrients: "Foliar fertilization with primary nutrients will not provide the quantities of nutrients required for normal plant growth. This product may cause foliar burn if applied in higher than recommended rates or concentrations. Use only as a supplement to a regular fertilization program."
2. The following clear and conspicuous written statement if the fertilizer label guarantees secondary nutrients or micronutrients: "Foliar fertilization can be an effective remedy for diagnosed plant deficiencies of secondary nutrients and micronutrients, but may cause plant damage if applied at more than recommended rates or concentrations. Use of this product is recommended only as a supplement to a regular fertilization program and only on plants with confirmed secondary nutrient or micronutrient deficiencies."
(6) USE DIRECTIONS. (a) The label of a fertilizer product for which a permit is required under s. ATCP 40.12(1) shall clearly disclose all of the following:1.

(a) may be deceptive or misleading. A failure to require supplementary disclosures does not constitute a finding, by the department, that the product is properly labeled. Note: For example, if a label implies that a product is effective for an entire season, but the product does not provide enough nutrients for season-long effectiveness when applied according to label directions, the department might require supplementary disclosures to remedy the deceptive or misleading implication. Disclosures might include, for example, a limitation of efficacy claims or a disclosure of nutrient amounts compared to annual plant nutrient needs.

The person shall have that scientific evidence before making the performance claim. Testimonials are not scientific evidence under this subdivision.(b) The department may require a person to submit substantiating information under par. (a). The department may require the person to submit the information before or after the department issues a license under s. ATCP 40.04 or a permit under s. ATCP 40.12. The issuance of a license or permit does not create any finding or presumption that the license or permit holder has complied with par. (a).(8) TERMS AND DEFINITIONS.
