Abstract:
Avocado trees suffering frcra chlorosis due to iron deficiency are found quite often in many orchards in Israel. Various iron compounds and methods of application have been tried, with differing levels of success. Excellent results were obtained with soil application of the iron chelate Sequestrene-138, (FeEDDHA), both in avoiding lime-induced chlorosis and in curing it in commercial avocado orchards. Foliar applications of all iron compounds tried (including FeEDDHA) did not produce good results, probably because of poor penetration and translocation through avocado leaves. Direct pressure injection of 0.5-1% FeEDDHA solution into the trunk or main branches of severely chlorotic adult trees brought about a very rapid greening of the leaves and recovery of the trees within 7–10 days. The present common practice in most avocado orchards planted on calcareous soils in Israel is to supply 1–2 ppm of FeEDDHA via the water of the irrigation system. © 1982, Taylor & Francis Group, LLC.
