Sampling for Botrytis cinerea in Harvested Grape Berries

摘要: The effect of aggregation disease on estimating the amount Botrytis cinerea in harvested winegrapes was simulated using computer models. As degree increased, estimated increased. This error reduced when more samples were obtained. When multiple (90) taken from gondolas containing machine- or hand-harvested berries and B. -specific antigen quantified with an immunoassay, machine-harvested had a uniform distribution than did berries. To obtain same confidence estimation level disease, one would take at least two per each gondola for
