Abstract

CU II hydroxide, (Cu(OH)₂) a fungicide, produces injury as a result of "chemical burn" or phytotoxicity on some plants. Scanning electron microscopy and energy dispersive X-ray analysis were used to characterize chlorosis on red maple leaves following foliar applications of Cu(OH)₂. Copper was located with X-ray mapping in foliar mesophyll cells of trees sprayed with Cu(OH)₂ but not in leaves of trees sprayed with distilled H₂O.
