Application Notes
Pentachloronitrobenzene (PCNB) is known as a broad spectrum contact antimycotic. According to the Fungicide Resistance Action Committee (FRAC), PCNB is listed as a lipid and membrane synthesis inhibitor (Fishel 2006).
PCNB has been documented to have activity against soil-borne bacteria, such as Rhizoctonia solani, Sclerotium rolfsii and Streptomyces scabies. It will also suppress the growth of actinomycetes and Rhizopus (Katan & Lockwood 1970).
PCNB can be used as a seed treatment, and is noted for this use by the International Seed Testing Association (ISTA) in method 7-009: Detection of Fusarium circinatum on Pinus spp. (ISTA 2011).
