INTRODUCTION

GCP/CPR/009/BEL, a Sino-Belgian financed FAO Project, is pleased to present in a single volume two manuals on poplar pathology, as occuring in its working area, notably the South-East of the Autonomous Region of Inner Mongolia, extending into adjacent counties of Jilin and Liaoning Provinces. Most of this area falls within the boundaries of the Korqin Sandy Lands, with its particular climatic conditions as described in part 2 of this volume.

The Project, in collaboration with the Ministry of Forestry and more precisely implemented by the Three North Bureau, has been functioning from 1990 until this year, when its First Phase will take an end. It has been concentrating on poplar breeding, afforestation techniques, mechanised planting methods and training, within the frame work of enhancing land and water conservation as well as expanding the local wood resources.

Part 1 of this volume concentrates on insects, giving a clear distinction to key, important and common pests. Stem borers are considered to be most detrimental (key pests), as proven by recent attacks in the Project Area. The authors give clear guidance to pest control. in a concept of Integrated Pest Management, taking into account the pest, the plant and the environment in a scheduled plan of activities.

Part 2 focuses on diseases (cankers, bacteria, fungi) urging for preventive measures, while giving well defined information on curative interventions. The authors estimate that no immediate large-scale threats are in existence.

Both parts have been written by internationally recognized experts, in an excellent collaboration with the College of Forest Resources and Environment of the Beijing Forestry University, that through the persons of Professor Zhenyu Li (entomologist) and Associate Professor Wei He (pathologist) also give a helping hand in checking the documents. They contain well chosen illustrations, colour pictures that illustrate both the agents and / or the symptoms of their presence on the host plants.

It is hoped that the present book will stimulate further interest in the study of forest insects and pathology in North-Eastern China, and-above all-that it will constitute a valuable tool in containing eventual outbreaks of pests and diseases in the nurseries and extensive poplar plantations of the area.
