Oregon’s New List Of Pesticides OK For Marijuana Means Changes For Some Growers

OREGON: Oregon on Monday issued a list of more than 250 pesticides cannabis growers may be able to use on their crops.

The list represents the first clear guidance from Oregon agriculture officials on what chemicals the state’s marijuana industry may use to defeat mites, mold, mildew and other common pests and problems. Top state agriculture officials made clear that the list is a “starting spot” for marijuana growers, who still have to follow pesticide labels.

Lauren Henderson, assistant director of the agency, said regulators combed through more than 12,000 pesticides registered with the state to see which had labels broad enough to include cannabis. Ultimately, the agency came up with about 250 products. The list will be reviewed quarterly, said Henderson.

University of New Haven Developing New Method To Test Marijuana For Mold, Other Contaminants

CONNECTICUT:  The microscope at the University of New Haven, set at 10-times magnification, shows a marijuana leaf covered with dozens of tiny bumps. It’s mold, and someone, somewhere could be smoking similarly contaminated pot and not have a clue.

Heather Miller Coyle, a forensic botanist and associate professor at the university, says all sorts of nasty things not visible to the naked eye have been found in marijuana — mold, mildew, insect parts, salmonella and E. coli, to name a few.

That’s why Coyle and her students earlier this year began developing a new process to detect contaminants in marijuana through DNA profiling and analysis. The aim is to be able to identify potentially harmful substances through a testing method that could make the analysis easier and quicker for labs across the country in the developing industry of marijuana quality control testing.
