Thiophanate-methyl Chemical Properties,Usage,Production

Description

Thiophanate methyl is a member of benzimidazole and a systemic fungicide with protective and curative activity against a broad spectrum of fungal diseases including leaf spots, blotches, blights, fruit spots, rots, sooty mould, scabs, bulb/corn/tuber decays, blossom blights, powdery mildews, certain rusts, and common soil borne crown and root rots. It is used on a variety of tree, vine, root crops, canola, and wheat, as well as on lawns and ornamentals. Thiophanate methyl is absorbed by the roots and leaves. Thiophanate-methyl has a low mammalian toxicity. But, it is an irritant and a skin sensitizer. It may also be mutagen. Moderate toxicity of thiophanate methyl is observed for aquatic organisms and earthworms. In EU, thiophanate methyl is approved to control fungal diseases on crops, while in Australia it is not registered for use on food-producing species, while it is only for the control of soil-borne diseases of ornamentals plants. For application, Thiophanate-methyl is formulated into wettable powders containing 50 and 70% active ingredient.

Chemical Properties

Methyl thiophanate is a colorless crystals, prisms or light brown powder.

Uses

Thiophanate methyl is a fungicide/wound protectant used to control plant diseases in stone fruit, pome fruit, tropical and subtropical fruit crops, grapes and fruiting vegetables. Thiophanate methyl is effective against a wide variety of fungal diseases such as leaf spots, blotches and blights; fruit spots and rots; sooty mould; scabs; bulb, corn and tuber decays; blossom blights; powdery mildews; certain rusts; and common soil borne crown and root rots.

Uses

Thiophanate-Methyl is a systematic fungicide of the thiophanate class. Thiophanate-Methyl is commonly used in agriculture to protect against powdery mildew, rot and other fungal diseases in fruits, ve getables and other crops.

Uses

Systemic fungicide.

Potential Exposure

Methyl thiophanate is thiocarbamate ester, used in the synthesis of polymers and in agriculture as pesticides, soil fumigants, and seed disinfectants.

Carcinogenicity

Those long-term studies evaluated a variety of toxicity end points including carcinogenicity. Both benomyl and carbendazim were weak carcinogens in some in vivo studies. Rats of the SpDxAug strain were fed 80, 400, and 2000 ppm for 2 years and no evidence for an increase in tumors was seen. In carcinogenicity studies in mice with carbendazim, similar liver tumor finding were found in CD-1 or Swiss strains. On the other hand, no evidence of tumors was seen in a similar study conducted using the NMRKf mouse strain, a strain that has a low incidence of spontaneous tumors.

Metabolic pathway

Thiophanate methyl degradation in water (hydrolytic/ photolysis), soils, plants and animals follows a common pathway that involves the initial conversion into methyl benzimidazol-2-ylcarbamate (carbendazim). Prior to benzimidazole ring formation, at least one side chain undergoes an oxidative desulfuration reaction and partial hydrolysis (even to the substituted aniline). Once formed, carbendazim is degraded primarily via an oxidative mechanism (in animals) or through hydrolysis to 2-aminobenzimidazole (in soils). Possible metabolism pathways of thiophanate methyl are depicted in Scheme 1.

Degradation

Thiophanate methyl (1) is susceptible to alkaline hydrolysis. The principal degradation product is carbendazim (2). Thiophanate methyl degraded slowly in water (pH 7-7.4, Noguchi et al., 1971), and in fruit juice (grape homogenate, Shiga et al., 1985) to primarily carbendazim, but also to 1-(3- methoxycarbony1thioureido)-2-(3-methoxycarbony1ureido)benzene (3) and dimethyl 4,4'-(o-phenylene)bis(allophanate) (4). Thiophanate methyl underwent photolysis in aqueous solution to carbendazim (DT50 <1 day) when illuminated with UV light (254 nm) or natural sunlight. A similar photolytic transformation occurred on moist cotton foliage, although no photolysis occurred when thiophanate methyl was exposed as a dry film to light (Buchenauer et al., 1973). Thiophanate methyl on wet filter paper decomposed in sunlight to yield carbendazim and small amounts of compounds 3 and 4 (Ono and Tohyama, 1982).

Incompatibilities

Thiocarbamate esters are combustible; dust may form explosive mixture with air. Decomposes163℃Thiocarbamate esters are combustible. They react violently with powerful oxidizers such as calcium hypochlorite. Poisonous gases are generated by the thermal decomposition of thiocarbamate compounds, including carbon disulfide, oxides of sulfur, oxides of nitrogen, hydrogen sulfide, ammonia, and methylamine. Thio and dithio carbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids. Flammable gases are generated by the combination of thiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates are incompatible with acids, peroxides, and acid halides.

Waste Disposal

In accordance with 40CFR 165 recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
