A greenhouse experiment was carried out with gladiolus and lily cultivars to determine the effects of additions to soil of a soluble F compound. NaF at 3 levels was mixed with virgin Myakka fine sand limed to 2 pH levels. Gladiolus and other test plants were grown in quadruplicate 9 inch plastic containers. Leaf scorch and foliar F data were collected on 6-7 inch leaf tip samples. F was determined by an adaptation of a method used in the analysis of feeds. Liming to the high pH reduced scorch and F uptake to a tolerable minimum. A trace of leaf scorch, however, appears to be associated with some other factors related to soil acidity for the low pH, 0 NaF treatment. NaF at the lower pH was toxic as shown by scorch. The high rate of NaF was more effective than the intermediate rate in causing scorch. A close positive correlation between leaf F and scorch is apparent on inspection of data.
