For example, searching for possum fertility will return documents containing either "possum" or "fertility" or both. If you're looking for more than one word in a document, place the word "AND" between the words. For example, if you're looking for documents which contain both possum and fertility, search for possum and fertility. To find a document with the exact phrase possum fertility enclose the query in quotes. ie: " possum fertility ".

A Guide to Diagnosing Diseases of Landscape Plants Author: Chuan Hong, Extension Specialist; Tom Banko, Associate Professor; and Marcia Stefani, Research Specialist; Virginia Tech Publication Number: 450-800, Posted January 2003 What Causes Landscape Plant Failure Plant failures are common in the landscape. Some occur soon after planting, while others develop over time. "What causes plant failures in the landscape?" is a question that homeowners, landscapers, contractors and educators frequently ask. Answers to this question will help not only to diagnose, but also to prevent similar problems in the future. In Virginia, analysis of plant disease samples received from the local landscape industry and homeowners reveals that environmental stresses and/or improper cultural practices are the primary causes of plant failure in the landscape. The majority of plant failures occur soon after planting. The transition from container-growth, under controlled conditions in a nursery, to the landscape can be very difficult. If an appropriate planting site and proper cultural conditions are not provided, the plant will not establish adequately, and is likely to die. Frequently, insufficient irrigation during the establishment period is a major cause of plant failure. However, too much water due to severe weather, watering too frequently, or poor soil drainage may also cause plants to die or become diseased. Salinity of the soil and the quality of well water used for irrigation are other common concerns in the eastern part of the mid-Atlantic region.

Managing Plant Diseases with Biofungicides Virginia Vegetable, Small Fruit and Specialty Crops November 2002; Volume 1, Issue 11 Cathy Thomas, Integrated Pest Management Program, Pennsylvania Department of Agriculture Editors note: the following article was taken from the Vegetable and Small Fruit Gazette, November 2002 issue. The newsletter can be accessed on the web at: http://hortweb.cas.psu.edu/extension/vegcrops/newsletterlist.html Diseases in greenhouse vegetables and floriculture crops can be managed effectively with biological fungicides (biofungicides). A biofungicide is composed of beneficial microorganisms, such as specialized fungi and bacteria that attack and control plant pathogens and the diseases they cause (USDA). These specialized fungi and bacteria are microorganisms that normally inhabit most soils. Biofungicides can be a viable alternative to chemical fungicides and can be used as part of an integrated disease management program to reduce the risk of pathogens developing resistance to traditional chemical based fungicides. An example of a widely used commercial biofungicide in the greenhouse industry is Trichoderma harzianum (TH) strain T-22 (PlantshieldÔ). TH protects plant roots from pathogens such as Pythium, Rhizoctonia, Fusarium, Sclerotinia, and Thielaviopsis. TH will also suppress foliar diseases such as Botrytis and powdery mildew.

Diseases represent a serious hazard to the production of a quality poinsettia crop. Control of poinsettia diseases should be based on disease prevention because once disease producing organisms invade plant tissue, control is much more difficult and expensive and frequently not too successful. Growers should become familiar with the common poinsettia diseases and for each disease they should have a basic understanding of: (I) the causal organism involved; (II) likely sources of pathogen introduction; (III) conditions required for plant infection and disease development; (IV) and, effective disease control measures. (I) Causal organisms of poinsettia diseases Bacterial and fungal pathogens are most commonly involved in damage to commercial poinsettia production in Texas. Poinsettia diseases and subsequent plant losses due to fungal pathogens cause more damage and monetary loss than do bacterial pathogens, but where bacterial diseases are severe, extensive losses can occur. Both bacteria and fungi are microscopic in most forms and because of this, it is impossible to detect their presence until plant infection and subsequent plant deterioration occurs. Therefore, it is important to anticipate potential disease problems and to modify the greenhouse environment or initiate preventive chemical control to minimize plant loss to disease. (II) Sources of pathogen introduction Potential poinsettia pathogens can be introduced into a greenhouse in several ways. Some pathogens, such as

Table of Contents Least-Toxic Controls of Plant Diseases by William Quarles The best way to control plant diseases is to make sure they don't get a foothold in the garden in the first place. ( Click here for Nine Steps to Disease Prevention ) However, if they are already established, you may feel it's necessary to resort to one of the controls described below. Most of these mentioned here have low acute toxicity to mammals, including humans, and are not toxic to beneficial insects. Some, such as baking soda, are practically non-toxic, while others, including bordeaux mixture, lime-sulfur, concentrated silicate salts, and streptomycin should be used with caution. Always follow application instructions carefully and apply only at the appropriate time in the plant's growth cycle and at the proper time of day. Be sure to protect yourself using the proper precautions when applying these controls. It is wise to avoid inhaling any kind of pesticide spray. Fungal Diseases Salt Sprays Horticultural Oils Soaps ... Controlling Soilborne Pathogens Controlling Fungal Diseases Most garden diseases are caused by fungi: more than 8,000 species are known plant pathogens and either inhabit the aboveground portions of plants or are denizens of the soil. Most of the fungicides described below are essentially preventive measures, acting as barriers between pathogenic agents and plant tissues, and must be applied before new leaves or other susceptible plant parts appear, at the first sign of disease, or when weather conditions are favorable for disease.
