History Has been used as a pesticide for many years.
Manufacturers Agrochem; Aimco; BASF; Cerexagri; Crystal; Drexel; Excel; FMC; Sharda; Syngenta

Biochemistry Non-specific thiol reactant, inhibiting respiration.
Mode of action Non-systemic protective fungicide with contact and vapour action. Secondary acaricidal activity.
Uses Control of scab on apples, pears, and peaches; powdery mildews on a range of crops, including fruit (at 1.75-6.25 kg/ha), vines (4-10 kg/ha), hops (1.75-6.25 kg/ha), beet (6 kg/ha), cereals (8 kg/ha), citrus (c. 6 kg/ha), ornamentals, cucumbers, vegetables, and in forestry (1.2 kg/ha); shot-hole of stone fruit; and acarinosis of vines. Also controls mites (particularly eriophyid mites) on a range of crops.
Phytotoxicity Phytotoxic, to some extent, to a number of crops, including cucurbits, apricots, raspberries, and certain other 'sulfur-shy' varieties.
Formulation types DP; MG; SC; WG; WP.
Compatibility For reasons of phytotoxicity, mixing with oils should be avoided.

Product analysis is by conversion to sodium thiosulfate which is determined by titration (CIPAC Handbook, 1992, E, 202-210; FAO Plant Prot. Bull., 1961, 9(5), 80).
Residues may be determined by colorimetry (H. A. Ory et al., Analyst (London), 1957,82, 189).

Oral Acute oral LD50 for rats >5000 mg/kg.
Skin and eye Irritating to skin, eyes, and mucous membranes; (not observed with 'Kumulus DF', 'Thiovit Jet').
Other Practically non-toxic to humans and animals.
Toxicity class WHO (a.i.) U; EPA (formulation) IV

Birds Acute oral LC50 (8 d) for bobwhite quail >5000 ppm.
Fish Non-toxic to fish.
Daphnia LC50 (48 h, static) >665 mg/l.
Algae EC50 (72 h) for Ankistrodesmus bibraianus >232 mg/l.
Bees Non-toxic to bees.
Worms LC50 (14 d) >1600 mg/l.
Other beneficial spp. Non-toxic to Coccinella septempunctata, Amblyseius potentilla, Amblyseius finlandicus, Anthocoris nemorum, Chrysoperla carnea. Toxic to Typhlodromus pyri, Trichogramma cacoeciae, Coccyfornimus turionellae.

Plants Degradation proceeds primarily by microbial reduction in and on plants.
Soil/Environment Insoluble in water, no leaching potential into ground water. When oxidised to sulfate, its contribution as sulfate ions from pesticidal sources is negligible in comparison with the natural occurrence of sulfates in soil and water.
