Abstract
IN 1961, protective spraying of tea plants with nickel chloride hexahydrate gave dramatic control of the blister blight disease1, and later certain salts of nickel were shown to possess eradicative control properties when applied in a dilute aqueous solution to tea foliage 3–5 days after inoculation with Exobasidium vexans Massee, the causal pathogen2. Very recently it has been observed that, in soils augmented with nickel ammonium sulphate and nickel nitrate, tea plants developed disease resistance.
