Aug 16, 2018

Boscalid is an agricultural fungicide active against a broad range of fungal pathogens such as alternaria blight, botrytis, powdery mildew, purple blotch, rust, leaf spot, target spot, brown spot, white mold, gray mold, stem rot and sclerotinia. It is applied to a variety of crops and vegetables including beans, brassicas, onions, garlic, shallots, peas, carrots, turnips; soybeans; fruits including grapes, apples, pears, strawberries; and tree nuts.

Boscalid is also used as a seed treatment and protectant. The pure compound is characterized as a white crystalline powder. It is often supplied as soluble granules which are mixed with water and applied as a spray. It has a molecular formula of C18H12Cl2N2O.

The United States Environmental Protection Agency (EPA) classified boscalid as “suggestive evidence of carcinogenicity, but not sufficient to assess human carcinogenic potential.”

Boscalid has a low toxicity in animal studies. Boscalid generally caused side effects on the liver as well as on the thyroid.

Boscalid may be found in related substances such as epoxiconazole, pyraclostrobin and fatty alcohol ethoxylate. In addition, some products like Filan, Signum, Splice, Tracker, Venture, Emerald, Bosco WG may contain boscalid as an active ingredient.

Manufacturers such as BASF and Goldengrass may supply such products historically or actively.
