    •Intensive pest management Wider spacing between trees “Manicured lawn! Precision positioning of trees Things you can see: Summary Selecting outstanding phenotypes is expensive Progeny testing is expensive (both time and money) Seed orchards are expensive Is it worth it? Yes! IF: Large area devoted to plantation culture of a single species. Douglas-fir and ponderosa pine have been studied more thoroughly than those of other Pacific Northwest timber species. Some of the more common fungi are listed in Table on page Fungus biology The process through which fungi become established on Douglas-fir seed has been well documented. Less information is available for other tree.

    A Guide to Insect Pests in Douglas­ Fir Seed Orchards D. S. Ruth This guide covers the majority of insects that feed upon cones and seeds, or destroy potential cone-bearingbranches, in Douglas-firseed orchards. Emphasis is on the recognition of the various stages of insect development and damage. A section is included on insect control. BC-X The main task of seed orchards is to ensure the production of abundant and frequently harvested genetic-quality seed for reforestation, without scarifying genetic gain and diversity [].Clonal orchards are the most common type, as they secure the transmission of the selected genes to the seed crops [].For cost saving and management ease, seed orchards are generally wind Cited by: 2.

    June - Provincial Pest Management Specialist March Ontario Forest Research Institute, Ontario Ministry of Natural Resources, Sault Ste. Marie, Ont. iDevelop and implement a pest management program (operational and research) to service Ontario tree improvement (50+ seed orchards). A plantation is the large-scale estate meant for farming that specializes in cash crops that are grown include cotton, coffee, tea, cocoa, sugar cane, sisal, oil seeds, oil palms, fruits, rubber trees, and forest trees. Protectionist policies and natural comparative advantage have sometimes contributed to determining where plantations are located.

Without pest management expertise, seed crops are at risk of damage or destruction caused by pest insects and diseases.

Such damage could result in short-term revenue losses due to pest activity in seed orchards, the collection of badly-infested cone crops, and longer-term repercussions for reforestation and future fibre production.

For seed orchards there are two areas of limitation. Firstly, maximal genetic gain can only occur if the orchard performs as a closed and perfect population.

However, seed orchard research has indicated this is affected by sub-optimal reproductive synchrony, varying proportion of gamete production among genotypes, pollen contamination and.

This guide to the recognition, biology and injuriousness of insects that infest Douglas fir (Pseudotsuga menziesii) is intended for seed-orchard workers in western Canada. It contains information on 15 species that feed on the cones and seeds, or destroy potential cone-bearing branches, and includes a general section on insect by: 6.

Cause A binucleate Rhizoctonia-like fungus, but not the same one that causes root rot or damping-off of disease affects grand, noble, and Douglas-fir. Concerns about the disease in western Hemlock increased substantially in Some studies have shown balsam fir and Sitka spruce may also be susceptible.

Thus, M. spermotrophus became the major seed pest of Douglas-fir seed orchards and plantations in Europe, with damage rates of up to % of the seeds (Roques ). As with Radiata pine, Douglas-fir has had its own breeding programme dating back to when seed was imported for a series of provenance trials.

This programme stalled somewhat in the late 70's because of Swiss Needle Cast – it was restarted in and continued from under the auspices of the Douglas-fir Coop and more latterly Future.

decade of research conducted on Douglas-fir seed orchards in British Columbia, Canada. Firstly, the seed orchards basic assumptions (i.e., reproductive synchrony, parental balance, minimal inbreeding, isolation, and random mating) were systematically examined in clonal and seedling orchards.

Secondly, the impact of two crop management techniques. A computer model which predicts transport and behaviour of pesticide sprays released from aircraft was used to predict canopy penetration and deposition in a Douglas fir [Pseudotsuga menziesii] seed orchard and the results were compared with card and string line data recorded on the ground.

Simulation of canopy penetration and deposition was in good agreement with the Cited by: 1. Forest and right-of-way pest control.

The cost of establishing and managing these orchards is substantial and will increase as new second-generation orchards are added.

Therefore, it is a good time to rethink our approach to seed orchard design and management in the region. Relationship between total seed produced, seed loss to insects, and seed yield in a Douglas-fir seed orchard in western Oregon, USA.
