These vendors are in Portland, but it’s possible that some Marion Co. suppliers may have used the same source, so heads up.
Shared by our state MG Coordinator:
Yesterday, the Oregon Department of Agriculture issued a press release related to clopyralid-contaminated compost and soil traces to two Portland-area suppliers. Clopyralid is an herbicide that can damage plants at low levels, and that can persist in soil for 2+ years.
The press release can be accessed, below. I’ll link a useful article on clopyralid damaged plants (with photos) in the comments. If your plants are showing signs of herbicide damage, the press release gives options for what to do, next.
Editor: And this is the link to the article on KOIN.com.
Plus supplemental information in one of the comments posted by our Coordinator: “Clopyralid can cause symptoms in plants at very low levels and only affects certain groups of plants, including legumes (peas, beans, lupine), composites (sunflowers, marigolds, lettuce), nightshades (tomatoes, potatoes, peppers), and buckwheat. Clopyralid does not affect grasses, corn, berries, cole crops (includes cauliflower, brussels sprouts, and kale), tree fruit, or the vast majority of woody and perennial ornamental plants.” https://www.einpresswire.com/…/oda-discovers…
