Content of Elementary Copper in Hops after Repeated Applications of Copper Fungicides
Original language description
Contents of elementary copper in hop cones are up to 500 mg/kg if total amount of applied copper does not exceed amount of 15 kg/ha. Contents of copper 1n leaves are 2-5 times higher at the same application dose. Application of 5 kg copper per one hectare of vigorous growth of Agnus variety increases content of copper on hop leaves by 1000 mg/kg at least. The same amout of copper increases its content in hop cones by 300 mg/kg at the ripening period. Copper content in hop cones shows decreasing trend, which is given by gradual increase of cones size during ripening period. Similar trend on hop leaves shows that washing and dissolving of copper compounds by atmospheric water can participate in this process as well. Common content of copper in hop conesand leaves is up to 20-25 mg/kg.
