[Archive] Christmas tree pests

When conifers have been grown for Christmas trees in lowland arable farmland areas under an intensive short-rotation system, it has sometimes been found difficult to produce good quality foliage without embarking on some kind of insect control. Thirty-one species of aphids, moths, sawflies, beetles and mites are of concern to growers of Christmas trees in […]

[Archive] Diseases and disorders of forest trees: a guide to identifying causes of ill health in woods and plantations

Part I provides some useful guidelines by which managers and owners can investigate health problems in their trees through straightforward field observations. Part II is a key to the major problems of plantation trees. Part III describes the main features of some of the more common and most important diseases and disorders of forest trees […]

[Archive] Weed control in Christmas tree plantations

Good weed control is essential for quality Christmas tree production. Herbicides are usually the most cost-effective way of achieving this. Two principal categories of Christmas tree production can be identified: production in forest plantations and specialist horticultural production. For these two situations, suitable candidate herbicides are identified, and guidance on their safe and effective use […]

[Archive] De-icing salt damage to trees and shrubs

The damage caused by de-icing salt is a serious, but often underestimated, problem which affects substantial numbers of roadside trees and shrubs both in Britain and abroad. This Bulletin has resulted from an extensive review of the world literature on the subject; the findings fall into four distinct categories which comprise its four chapters. Chapter […]

[Archive] Honey fungus

Honey fungus is one of the commonest root diseases of trees and shrubs in the world. It can kill an enormous range of plants and also causes decay in standing trees. It is rarely a major problem in woodland although it sometimes kills large groups of conifers in young plantations. The disease is more serious […]

[Archive] Ash dieback – a survey of non-woodland trees

During the summer of 1987 a survey of dieback in non-woodland ash trees was undertaken in Great Britain. After excluding certain areas due to their known low ash population, two hundred 10 km squares were visited and detailed data collected on the condition of ash in a plot selected within each square. Information was obtained […]

[Archive] Research for practical arboriculture

This Bulletin records the proceedings of a seminar held at York University in April 1990, organised jointly by the Arboricultural Association and the Forestry Commission. The seminar was the third of its kind, held every 5 years, since 1980, updating the arboriculture industry on current arboriculture research in the United Kingdom. Twenty-six papers are presented […]
