Active ingredient	Copper hydroxide
Chemical name	copper hydroxide (Cu(OH)2)
Classification	Fungicide / Agrochemical
Formulation	77% WP
Biochemistry	Non-specific thiol reactant, inhibiting respiration. Copper-II-ion (Cu++) is taken up by the spores during germination and accumulates until a sufficiently high concentration is achieved to kill the spore cell; the activity is limited to the prevention of spore germination.
Mode of action	Protectant fungicide and bactericide. Deposits must be on the crop before fungal spores begin to germinate.
Usage	For control of Peronosporaceae in vines, hops, and brassicas; Alternaria and Phytophthora in potatoes; Septoria in celery; and Septoria, Leptosphaeria, and Mycosphaerella in cereals
Toxicology	Oral: Acute oral LD50 for rats 489 mg/kg (tech.). Skin and eye: Acute percutaneous LD50 for rabbits >3160 mg/kg. Severely irritating and corrosive to eyes, mild skin irritant. Inhalation: LC50 > 2 mg/l air.
