Incidence of leaf scorch of Ace lilies as influenced by fluoride applications

Applications of sodium fluoride will induce greater amounts of leaf scorch than would otherwise be the case. Leaf scorch can be minimized by incorporating adequate limestone, maintaining a high pH level, fertilizing with calcium and potassium nitrate and avoiding use of materials containing fluoride. Although low phosphorus levels appear beneficial, a deficiency must be avoided. Plants with equivalent quantities of phosphorus from triple superphosphate had less fluoride in the leaves and less leaf scorch than with ordinary superphosphate. Dicalcium phosphate was even more effective in reduction of the fluoride content of lily leaves. 19 references, 1 table.
