What the Sil Matrix Registration Actually Covers
Three registrations in one product is unusual, so it is worth being precise about the claims. The EPA label covers it as a fungicide, a miticide and an insecticide under registration number 70051-127.
Purchase directly from Growers HouseWhat the Sil Matrix Registration Actually Covers
Three registrations in one product is unusual, so it is worth being precise about the claims. The EPA label covers it as a fungicide, a miticide and an insecticide under registration number 70051-127. The active ingredient is potassium silicate at 29 percent, with other ingredients making up 71 percent. The signal word is CAUTION, re-entry is four hours, and it may be applied up to the day of harvest. On the disease side the label names powdery mildew and gray mold rot on blueberry. Suppression claims cover Asian soybean rust, plus gray leaf spot, brown patch, dollar spot and snow mold on turf. On the pest side it names spider mites, aphids and whiteflies. It is OMRI Listed for organic production.
How a Potassium Silicate Spray Does Two Jobs
The mechanism explains why one material covers both columns. Applied to foliage before infection, the silicon is taken into the plant cuticle and builds a mineral matrix inside the leaf surface. A fungus trying to push a penetration peg through that surface meets a harder barrier than it would on an untreated leaf. As the spray dries, residual silicate crystallises on the outside as well. That physical deposit is what disrupts soft bodied mites and insects on contact. Two consequences follow from that mechanism. Preventative timing matters far more than curative timing on the disease side, because a barrier built after infection protects nothing. And coverage matters on the pest side, since a contact deposit only works where the spray landed. The rate is 1 to 4 quarts per 100 gallons, which is a 0.25 to 1 percent solution. Run a jar test before tank mixing and a phytotoxicity trial watched for seven to ten days.
