Oregon flags potential problem with popular pesticide used on marijuana
The Oregon Department of Agriculture on Friday temporarily removed a popular pesticide from its list of chemicals cannabis growers may use on their crop.
Rodger Voelker, a chemist with OG Analytical, a marijuana testing lab in Eugene, said he recently noticed that abamectin, a common insecticide, had turned up in a handful of cannabis samples submitted by growers who said they grew organically. One mentioned he used only Guardian Mite Spray. Voelker asked for a sample of the mite spray, tested it and detected abamectin, an active ingredient not listed on the product label.
