UNRRA farm experts examines diseased trees in Greece. C.J. Alexopoulos, farm expert of the United Nations Relief and Rehabilitation Administration, examines cancer on branches of a clive tree in Greece. This disease, plus damage by olive fly and olive scalo, had made much of the Greek olive harvest unfit for table use. The diseases are common and widespread because the Greeks were unable to spray their trees during the Nazi occupation.
