| Abstract/Contents: | Discusses the proliferation of moss infestations, which are caused by decreasing mowing heights. Describes the biology of mosses, explaining that "mosses do not have roots and, in their absence, the plants anchor to a surface with rhyzoids attatched to a substrate. . .neither do mosses have a defined vascular system for water and nutrient delivery or, conversely, as a pathway to facilitate control or eradication." Describes the resilience of mosses, which are able to survive against long periods of dehydration. Discusses the morphology, ecology, electrochemistry, metal electrode potentials and chlorophll of mosses, especially Bryum argentium, the most common species of moss. Presents a hypothesis, which is that "silver, developing at least the same relative electrode potential as mercury, would galvanically destroy the chlorophyll in Bryum argentium as effectively as mercury." Details experiments and field trials done to test this hypothesis. Reports that "the assembly of a working Bryum argentium/silver nitrate battery cell experimentally confirmed both the hypothesis and the forecast." |
