This Technical Note outlines these application methods and provides details on the components of mechanised sprayers and herbicide delivery systems. Information is also provided on pre- and post-storage maintenance, sprayer testing and spray drift management. Conclusions and recommendations give guidance for the use of mechanised sprayers in forestry.
This Technical Note outlines legislation governing pesticide use and sets out training and certification requirements relevant to pesticide storage. It provides recommendations on planning, constructing and maintaining permanent and mobile pesticide stores and gives guidance on the management and safe storage of pesticides. Advice is also given on waste disposal, health and safety issues and […]
This booklet is planned as a forester’s guide to the recognition of the three most common and damaging decays of standing conifers in Great Britain.
The fungi that cause these rots are the basidiomycetes Heterobasidion annosum (formerly known as Fomes annosus), Armillaria mellea, and Polyporus schweinitzii. They are primary root rotting organisms, infection usually beginning in the […]
On moorland and heathland soils in Great Britain nitrogen deficiency can severely restrict the growth of certain conifer species, including Sitka spruce, the main commercial species. Until the 1970s this was thought to be due solely to competition from heather and was commonly known as ‘heather check’. However, increased planting of Sitka spruce on very […]
Ash is a widespread species which makes a substantial contribution to many landscapes. Ash trees are affected by ash dieback, a disease caused by a fungus. It is clear from the European experience of the disease that a significant number of ash trees could be lost from woodlands in the UK over the course of […]
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 […]
This Technical Paper updates information in Forestry Commission Field Book 8 The use of herbicides in the forest. It provides a summary of recent Forestry Commission research findings concerning the use of herbicides in forestry, and also explains relevant changes in legislation and approved products. Key herbicides cited in this publication: atrazine, cyanazine, cycloxydim, clopyralid, dichlobenil, […]
This document is assembled from a series of individual reports written by scientists and technicians from a number of organisations which took part in an operation carried out at short notice, to monitor the spraying of forests in northern Scotland to control the outbreaks of Pine beauty moth.Note: This is an archive publication.
