DENVER — A victory for The Denver Department of Environmental Health after a judge maintained the department’s hold on thousands of marijuana plants.

In March, the city quarantined thousands of plants from several cultivation sites because a pesticide may have been improperly used.

On March 25, the Denver Department of Environmental Health found evidence that plants at six locations had been contaminated by pesticides which are not approved by the Colorado Department of Agriculture. The businesses involved cannot sell the marijuana which has been placed on hold.

Grower Organic Greens Inc. asked Denver Court Judge John Madden to allow the marijuana to be cultivated. The debate centered over the use of a fungicide known as Eagle 20. The health department found logs at cultivation sites that show Eagle 20 was being used.

Sean McAllister, attorney for Organic Greens, said his client believes their product is safe and that they will explore all options to resolve the issue with the city of Denver.

Judge Madden heard arguments from both sides for four days before refusing to stop the pot quarantine.

Colorado’s Marijuana Enforcement Division has yet to establish testing of marijuana for the presence of contaminants. The state currently only requires testing marijuana for potency.

The Environmental Protection Agency (EPA) has yet to approve any pesticide/fungicide use on marijuana.
