In states like Colorado and Washington, there is a tremendous amount of money riding on healthy cannabis crops these days. But unlike, say, a corn farmer, growers in the legal-marijuana industry don’t have a clear understanding yet of which pesticides and fungicides are safe to use – for workers or consumers. Though the Environmental Protection Agency (EPA) regulates pesticide use on other crops, it has not tested any for use on marijuana because the plant remains illegal at the federal level. And without federal approval, the use of non-registered pesticides is technically a violation of the law.
The result is a regulatory void in which, theoretically, anything goes.
