An Mg-N formulation (RES-20482) used as a 0.25 or 0.50% spray solution or when trunk injected at 5 ml/2.54 cm of trunk circumference did not significantly increase leaf Mg of pecan (Carya illinoensis (Wang.) K. Koch).
Pressure trunk injection of Zn sulfate solutions rapidly increased leaf Zn levels of Zn deficient trees in pecan (Carya illinoensis (Wang.) K. Koch). Injection of 2270 g/tree killed foliage and twig terminals within one week. New foliage growth appeared normal but was high in Zn. Injected Rhodamine B dye indicates that solutions move rapidly to the extremities of the tree. Injected wood preservative “Osmose” killed trees within 10 days.
