Guide for the identification of lawn seed crops including tall fescue, annual ryegrass, perennial ryegrass, red fescue, chewings fescue, hard fescue, bluegrass, and bentgrasses. The Oregon State University affiliated author offers descriptions with identifying characteristics for each grass seed discussed.
A discussion about the control of basal rot of daffodils caused by the fungus Fusarium oxysporum F. sp. Narcissi. Topics discussed by the Washington State University affiliated author include basal rot lifecycle, and a series of recommendations on practices used to control basal rot of daffodils.
European rhododendron rust (Chrysomyxa ledi var rhododendri), is a disease which can lead to severe defoliation in rhododendrons and deciduous azaleas. The rust also affects it's alternative host, spruce (Picea sp.) and can cause severe defoliation. Symptoms, disease lifecycle, and control are discussed.
Guide for the prevention and control of Stromatinia, Curvularia, Botrytis, Fusarium corm rot, thrips, nematodes, bulb mites and aster yellows mycoplasm. Information provided on how to cure and store gladiolus corms, dormancy, and Rhizoctonia solani.
Research conducted on growth and flower bud formation of three rhododendron cultivars grown with and without overhead irrigation. Authors were interested in determining the role of overhead irrigation and adequate soil moisture in preventing sunburned foliage.
Study conducted in response to reports from growers of bulb crops indicated a loss of Botrytis control with the fungicides Benlate and Chipco-26019 in both greenhouse and field-grown situations. The authors discuss the results, fungicide resistance and how to avoid fungicide resistance.
Survey of the most popular shade and flowering trees taken by the National Landscape Association (NLA) over a 26-year period. The NLA surveyed members from the Northeast, Southeast, Great Lakes, and Great Plains and based their tree selections on hardiness, maintenance, and aesthetics.
Increased interest in using biological control of insects by nurseries prompted the author to provide the brief report on using pathogenic nematodes for insect control. Topics discussed include nematode species, nematode lifecycle, host insects, and other factors.
The author discusses the importance of noxious weed control in nursery crops along with chemical control methods. Specific noxious weeds identified in nurseries include yellow nutsedge, quackgrass, Canada thistle, field bindweed, horsetail rush, blackberries, and dandelion.
