You may have noticed recently that some previously listed products are no longer on the OMRI (Organic Materials Review Institute) Products List. This past year, OMRI has been re-reviewing all products on their list for NOP compliance. The USDA National Organic Program (NOP) has recently revised its requirements for products to be approved for use in organic. The new requirements no longer allow the use of some inert ingredients (see full list below). Consequently, OMRI has withdrawn certification of a lot of products. Listing status is renewed annually, and another reason a product may fail to stay on the list is that some companies decide not to pay the listing fee. For companies with a small volume of sales, it can be a lot of money.
Two Rincon-Vitova products no longer listed as of September 2008 are BioStart Rhizoboost and Defensor. Bio-Cat, the manufacturer, is currently working on finding a preservative that will meet the new NOP standards. They haven’t given us a specific time frame, but testing a new formulation will take a few months and getting the products recertified by OMRI will take a few more months after that. We’ll keep you updated on their progress. We will continue to carry these products, but be aware that they are no longer approved for use in USDA certified organic production. If you need an OMRI listed microbial inoculant, we also carry Natural Resources Group’s Activate line of products. Hopefully a new formulation will be approved for organic soon because we have seen the benefits of these products extend beyond improving and maintaining soil biodiversity and promoting balance in the soil foodweb. Rhizoboost is especially helpful for farms in the first year of transition off of fumigated and chemically treated soils before moving the land towards organic certification.
Inert ingredients no longer allowed by NOP standards:
acetylated lanolin alcohol
acrylic acid methyl ester, polymer with acrylonitrile and 1,3-butadiene
polyglyceryl phthalate ester of coconut oil fatty acid
