Allowed with Restrictions
Crop Pest, Weed, and Disease Control
Synthetic
For use as an algicide in aquatic rice systems with documented need and for tadpole shrimp control in aquatic rice systems; use is not to exceed one application per field during any 24-month period. Application rates are limited to those which do not increase baseline soil test values for copper over a time frame agreed upon by the producer and accredited certifying agent. When used for plant disease control must be used in a manner that minimizes accumulation of copper in the soil. May only be used as an algicide, insecticide, or disease control if the requirements of 205.206(e) are met. When used as a plant or soil amendment it may be used as a micronutrient fertilizer, but may not be used as a defoliant, herbicide, or desiccant. Soil deficiency of copper must be documented by testing. See also COPPERS – MICRONUTRIENT.
