The publication of this PHYTOGUIDE would not have been possible without the excellent contribution and untiring efforts of staff of the Plant Protection Division, Ministry of Agriculture, TANZANIA. Much of the Field Verification Trials that established the technical content of the PHYTOGUIDE, would not have been possible without their able and very professional assistance. Special acknowledgment is extended to Mr. Valentine Ndibalema, Mr. William Menya, Mr. Gasana Rwabufigiri, Mr. Edmund T. Kasalile, Mr. Yusuf Nyakunga, Mr. R.L. Mashaka and Mr. William Riwa. Mr. Geoffrey I. Kirenga, ably assisted by Mrs Hossiana Mmbaga, have performed miracles in preparing, typesetting and formatting the manuscript.
This publication is dedicated to the memory of "Will" MENYA. His professionalism in expediting phytosanitary operations in Dar es Salaam Port will be sadly missed.
