Filter by Series

College publications are given 2-part "pub numbers" that are used to identify them. The first part (the prefix) is a set of letters that indicates which series the document belongs to. A series is a grouping of documents that share similar content.

The second part of the pub number is just a sequential number.

Series: Greenhouse Plant Disease: Plant Pathology Factsheet

Fungicides for Management of Diseases in Commercial Greenhouse Ornamentals
4/1/2016 (reviewed)

This guide is a decision-making tool to help growers select fungicides from different chemical classes (FRAC). Additional information can be found in a number of UK Cooperative Extension Service publications or by contacting county Extension agents. | PPFS-GH-3

Managing Greenhouse and High Tunnel Environments to Reduce Plant Diseases
3/1/2016 (new)

Greenhouse and high tunnel environments, which tend to be warm and humid, often create ideal situations for disease development. Environments favoring infection and spread of many disease pathogens include one or more of the following: high relative humidity (90% or above), free moisture (e.g., leaf wetness, wet soil), and/or warm temperature. Because diseases can cause extensive damage, their management is essential to production of high quality, marketable products. While challenging, these environments can be managed to simultaneously encourage plant growth and discourage pathogen spread. | PPFS-GH-1

Greenhouse Sanitation
3/1/2013 (new)

Diseases are a major concern for greenhouse growers and can be a key limitation to profitable plant production. Disease management in greenhouses is critical because the warm, humid environment in these structures provides optimal conditions for reproduction of many pathogens. When disease management is neglected, pathogen populations build-up and continue to increase as long as there is susceptible plant tissue available for infection and disease development. Infected plant tissue, infested soil, and pathogen inoculum (such as spores, bacterial cells, virus particles, nematode eggs) all serve as sources of pathogens that can later infect healthy plants. | PPFS-GH-4

Poinsettia Diseases
5/1/2010 (minor revision)

Poinsettias grown through the fall months for Christmas sales are vulnerable to destructive diseases from the time the cuttings are stuck into the rooting media until they are mature and ready for sale. A number of poinsettia diseases are favored by the same environmental conditions that promote propagation, making plant material at this stage particularly vulnerable. Diseases occurring in the later stages of production can be related to management issues or cultural problems, as well as the cooler temperatures needed for finishing. Some other diseases can be problematic to poinsettias at any phase of production. And finally, a phytoplasma organism found associated with poinsettias provides evidence that some host/pathogen relationships can actually be economically beneficial. | PPFS-GH-6

Controlling Phytophthora Root Rot in Greenhouse Ornamentals
5/1/2005 (minor revision)

Phytophthora fungi can attack a number of potted herbaceous ornamentals produced in greenhouses. The potted flowering plants reported as hosts include: begonia, bougainvillea, ornamental pepper, vinca, poinsettia, Persian violet, fuchsia, common gardenia, African daisy, kalanchoe, Lantana, African violet, holiday cactus, gloxinia, and Jerusalem cherry. | PPFS-GH-5
