Method of treating a plant or crop

摘要

A method of treating a plant or crop includes exposing the plant or crop to an aqueous treatment stream which contains a wetting agent and calcium hypochlorite. Calcium hypochlorite is introduced into an aqueous flow stream to produce a treatment stream. The calcium hypochlorite produces hypochlorous acid, hypochlorite ions, calcium ions and hydroxyl ions and it is introduced so as to produce a treatment stream having a calcium hypochlorite concentration of between about 0.19 and 0.38 mM and a calcium ion concentration of between about 0.19 and 0.38 mM. The wetting agent is added to the water from which the flow stream is generated or to the flow stream or to the treatment stream and the plant or crop is exposed to the treatment stream.
