APPLICATIONS Biochemistry: Non-specific thiol reactant, inhibiting respiration. Mode of action: Fungicide with protective action. Uses: Control of many fungal diseases (e.g. blight, leaf spot, rust, downy mildew, scab, etc.) in field crops, fruit, nuts, vegetables, ornamentals, etc. Particular uses include control of early and late blights of potatoes and tomatoes (at 1.36 kg a.i./ha); Rhizoctonia solani and Streptomyces scabies on seed potatoes; leaf spot diseases on celery, cucurbits, beet, berries and currants; rusts on cereals, vegetables, roses, carnations, asparagus, beans, apples and plums (at 1.6 kg/ha); downy mildews on hops, vines, onions, leeks, lettuce, cucurbits, ornamentals and tobacco; Gloeodes pomigena, Glomerella cingulata, Microthyriella rubi and Physalospora obtusa on apples; scab on apples and pears (at 2.4-3.6 kg/ha); sigatoka disease (Cercospora musae) in bananas; shot-hole of stone fruit; anthracnose of beans and cucurbits; damping-off diseases of vegetables; black leg of beet; needle cast in forestry; and many seed-borne diseases of cereals. Used for foliar application or as a seed treatment. Formulation types: DP; DS; SC; WG; WP. MAMMALIAN TOXICOLOGY Oral: Acute oral LD50 for rats >5000 mg/kg. Skin and eye: Acute percutaneous LD50 for rats >10 000, rabbits >5000 mg/kg. Mild to moderate skin irritant; moderate eye irritant. Inhalation: LC50 (4 h) for rats >5.14 mg/l. ADI: 0.03 mg/kg b.w. (group ADI with maneb, metiram and zineb); ethylenethiourea 0.004 mg/kg b.w. Other: At very high levels, mancozeb has caused birth defects in test animals; ethylenethiourea, a trace contaminant and breakdown product of mancozeb, has caused thyroid effects, tumours and birth defects in laboratory animals. Toxicity class: WHO (a.i.) III (Table 5); EPA (formulation) IV EC hazard: Xi; R37| R43 ECOTOXICOLOGY Birds: In 10-day dietary studies, there were no mortalities in mallard ducks at 6400 mg/kg daily, and in Japanese quail at 3200 mg/kg daily.
