ENVIRONMENTAL FATE

Animals Copper is an essential element and is under homeostatic control in mammals. Plants Plants resist copper accumulation and translocation to stems, leaves or seeds. Most plants growing on soils containing up to 1000 ppm copper showed only slight elevation in copper content compared to plants grown in normal soils. Soil/Environment Copper is a basic chemical element and does not dissipate in the soil. Soluble copper ions in the soil water are rapidly complexed by organic matter, precipitated as hydroxides, or insolubilised as precipitates with sulfides, hydroxides, carbonates, or phosphates.

Usage: Fungicide introduced in USA (1968) by Kennecott Corp. Manufacturers:  Crystal; Griffin; Ingeniería Industrial; Sulcosa

Application: 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. Protectant fungicide and bactericide. Deposits must be on the crop before fungal spores begin to germinate. For control of Peronosporaceae in vines, hops, and brassicas; Alternaria and Phytophthora in potatoes; Septoria in celery; and Septoria, Leptosphaeria, and Mycosphaerella in cereals, at 2-4 kg/ha or 300-400 g/100 l.
