Toxicity: 

Reviews	CAG (see part 2 of Bibliography)
IARC ref.	30; 73  class 2B
Oral	Acute oral LD50 for rats >5000 mg/kg.
Skin and eye	Acute percutaneous LD50 for albino rabbits >10 000 mg/kg. Severe eye irritant; mild skin irritant (rabbits). Evidence in humans of contact dermatitis
Inhalation	LC50 (1 h) for rats >4.7 mg/l air; (4 h) for rats (nominal concentration) 0.6 mg/l air; (4 h) for rats (actual) 0.10 mg/l air
NOEL	Chronic administration of chlorothalonil has been associated with tumour formation in the kidney and forestomach of rats and male mice. The mechanism has been demonstrated to be epigenetic with a NOEL of 1.8 in rats and 1.6 in mice. In dogs, the pattern of toxicity is different from that in rodents, with a NOEL of at least 3 mg/kg b.w. (JMPR 1990)
ADI	(JMPR) 0.03 mg/kg [1994]
Toxicity class	WHO (a.i.) III (Table 5); EPA (formulation) II ('Bravo' SC)
EC hazard	Xn; R40

 

 

 

Application:

Biochemistry	Conjugation with, and depletion of, thiols (particularly glutathione) from germinating fungal cells, leading to disruption of glycolysis and energy production, fungistasis and fungicidal action.
Mode of action	Non-systemic foliar fungicide with protective action.
Uses	Control of many fungal diseases in a wide range of crops, including pome fruit, stone fruit, citrus fruit, bush and cane fruit, cranberries, strawberries, pawpaws, bananas, mangoes, coconut palms, oil palms, rubber, pepper, vines, hops, vegetables, cucurbits, tobacco, coffee, tea, rice, soya beans, peanuts, potatoes, sugar beet, cotton, maize, ornamentals, mushrooms, and turf. Application rates for food crops are 1-2.5 kg/ha.
