Prothioconazole 丙硫菌唑

Introduction: Prothioconazole is a synthetic compound of the triazolinthione family of compounds. It is a broad spectrum systemic fungicide, with curative, preventative and eradicative action. It can be used as both a seed treatment and a foliar treatment. After absorption it moves into cells of the target organisms, effecting sterol biosynthesis and thereby disrupting membrane structure. This ultimately effects hyphal growth and germ tube elongation. Fungi susceptible to prothioconazole include Early leaf spot (Mycosphaerella arachidis), eyespot, Fusarium spp., powdery mildew, net blotch, phoma leaf spot, Rhynchosporium secalis, Sclerotinia sclerotiorum, Sclerotium rolfsii, Septoria tritici, Septoria nodorum, rust and tan spot. Prothioconazole is approved for use on barley, durum wheat, oats, oilseed rape (winter), rye (winter), and wheat.

ENVIRONMENTAL FATE

In animals: Prothioconazole is rapidly and extensively absorbed and rapidly eliminated, predominantly via faeces. It does not show potential for accumulation. Prothioconazole is extensively metabolised, with the major metabolic reactions being conjugation with glucuronic acid, oxidative hydroxylation of the phenyl moiety and desulfuration. In plants: The metabolism of prothioconazole proceeds through oxidative and cleavage reactions. The major metabolites are prothioconazole-desthio and triazolylalanine, triazolylhydroxypropionic acid and triazolylacetic acid. No free 1,2,4-triazole was detected in any plant matrix. In the soil: Prothioconazole is rapidly degraded to prothioconazole-desthio and prothioconazole-Smethyl. Parent compound and metabolites show low potential for leaching or accumulation. For prothioconazole, prothioconazole-desthio and prothioconazole-S-methyl, soil DT50 (lab., 20) 0.07-1.3d, 7-34 d, and 6-46 d, respy.; Koc 1765 ml/g, 523-625 ml/g and 1974-2995 ml/g, respy. Prothioconazole degraded rapidly in water/sediment systems under aerobic conditions (DT50 for total system 2-3 d); major metabolites are prothioconazole-desthio and 1,2,4-triazole (detected in the water layer) and prothioconazole-S-methyl (in sediment).

Usage: Prothioconazole was developed by Bayer Crop Science. It is used to protect Wheat, barley, rapeseed, peanut, rice and beans crops against a wide spectrum of fungal diseases. Also control the rapeseed and peanut soil borne disease, such as Sclerotinia sclerotiorum, and foliar diseases, such as Botrytis cinerea, black spot, brown spot, black shank, Sclerotinia sclerotiorum and rust. 
Application: Biochemistry Steroid demethylation (ergosterol biosynthesis) inhibitor. Mode of action Systemic fungicide with protective, curative, eradicative and long-lasting activity. Uses Under development for control of diseases such as eyespot (Pseudocercosporella herpotrichoides), Fusarium ear blight (Fusarium spp., Microdochium nivale), leaf blotch diseases (Septoria tritici, Leptosphaeria nodorum, Pyrenophora spp, Rhynchosporium secalis, etc), rust (Puccinia spp.), and powdery mildew (Blumeria graminis) by foliar application in wheat, barley and other crops. As a seed dressing, for control of Ustilago spp., Tilletia spp., Fusarium spp. and Microdochium nivale.
