This looks very interesting indeed, but the price may exclude a lot of people from buying it. I do like the fact that natural predators are not affected. Not available outside the US after searching the Web.
Available in Canada since late 2019. Will be interesting to hear if any UBC forum members have used it. BioWorks’ SuffOil-X horticultural spray oil is now available in Canada
Hmm. Smallest size 2.5 gallons on this Arizona page: SuffOil-X - Miticide, Insecticide and Fungicide (arbico-organics.com), which lists about 45 pests it's good for. That seems to contradict the initial impression given that it's so specifically targeted. Maybe none of the pests listed is a natural predator of spider mites.
As so often said, the devil is in the detail or smallprint. Wonder if @Junglekeeper has used it or knows anyone who has !!?
I was thrilled to learn that there's such a product to treat spider mites but I wonder how it differs from other horticultural oils. Would love to hear from someone who has used it. However given its price I doubt many have. Here is the link for the product on Bioworks Canadian site: SuffOil-X®- Canada - Canada | BioWorks
TetraCURB Concentrate, it seems, is more effective against mites: Evaluation of biorational insecticides against two-spotted spider mite (Acari: Tetranychidae) on Tomato. TetraCURB™ Concentrate - Rosemary oil-based biopesticide
Even more fascinating @Junglekeeper. Thanks for the added link. Price might stop a lot from trying this though.
