Abstract

The Tree Seed Pathology Working Group was formed in 1981 by members of the Forest Tree & Shrub Seed Committee of the International Seed Testing Association (ISTA). Since the beginning the working group's objectives have been to test the effectiveness of tree seed health techniques, to prepare results for ISTA Congress presentations, and to evaluate potential testing techniques for inclusion in forest seed handbooks.

The working group, under the leadership of Dr. R.L. Anderson and J. Shepard, has been very active; it has developed a new method for assessing contamination of Pinus elliottii and P. taeda seeds by Fusarium moniliforme var. subglutinans.

Literature on the microrganisms associated with tree seeds is available in diverse sources which are sometimes unavailable to seed researchers. Recognizing the need to collect all relevant information regarding distribution of tree seed pathogens around the world, Dr. Anderson published a checklist in 1986 which covered an extensive list of hosts, organisms and countries.

Because of the continuous flow of new information such a work is never complete and the present publication updates the checklist. The value and usefulness of this revision, made by Drs. R.K. Mital, R.L. Anderson and S.B. Mathur, is sure to be appreciated by nurserymen, pathologists and entomologists throughout the world.
