Plant Pathogens in recycled irrigation water in commercial Plant nurseries and greenhouses: their detection and management
Irrigation Science, 2011Co-Authors: Sally M. Stewart-wadeAbstract:With water conservation and reuse a priority for communities worldwide, recycling irrigation water in commercial Plant nurseries and greenhouses is a logical measure. Plant pathogenic microorganisms may be present in the initial water source, or may accrue and disperse from various points throughout the irrigation system, constituting a risk of disease to irrigated Plants. The continual recycling of this water is exacerbating this Plant disease risk. Accurate and timely detection of Plant pathogenic propagules in recycled irrigation water is required to assess disease risk. Both biological and economic thresholds must be established for important Plant-pathosystems. Plant Pathogens in recycled irrigation water can be managed by a variety of treatment methods that can be arranged in four broad categories: cultural, physical, chemical, and biological. An integrated approach using one or more techniques from each category is likely to be the most effective strategy in combating Plant Pathogens in recycled irrigation water.

Plant Pathogens in Irrigation Water: Challenges and Opportunities
Critical Reviews in Plant Sciences, 2005Co-Authors: Chuanxue Hong, Gary W. MoormanAbstract:Plant Pathogens in irrigation water were recognized early in the last century as a significant crop health issue. This issue has increased greatly in scope and degree of impact since that time and it will continue to be a problem as agriculture increasingly depends on the use of recycled water. Plant Pathogens detected from water resources include 17 species of Phytophthora, 26 of Pythium, 27 genera of fungi, 8 species of bacteria, 10 viruses, and 13 species of Plant parasitic nematodes. There is substantial evidence demonstrating that contaminated irrigation water is a primary, if not the sole, source of inoculum for Phytophthora diseases of numerous nursery, fruit, and vegetable crops. These findings pose great challenges and opportunities to the Plant pathology community. A variety of water treatment methods are available but few have been assessed for agricultural purposes under commercial conditions. Investigations into their technical feasibility and economics are urgently needed. Aquatic ecology of...

eradication of Plant Pathogens in forest nursery irrigation water
Plant Disease, 2013Co-Authors: Patricia Da S Machado, Acelino C Alfenas, Marcelo M Coutinho, Claudio Mudado Silva, Ann H Mounteer, Luiz A Maffia, Rodrigo G Freitas, Camila S FreitasAbstract:Abstract Interest in rational use and reuse of water has increased in recent years, especially in forest nurseries. However, before water can be reused in nurseries, it must be properly treated to eradicate Plant Pathogens to reduce risks of pathogen dispersal and losses to disease. In the present study, the efficacy of irrigation water treatment by ultrafiltration and conventional physical-chemical treatment was studied to eliminate Botrytis cinerea, Cylindrocladium candelabrum, Ralstonia solanacearum, and Xanthomonas axonopodis, the Pathogens most commonly found in Brazilian forest nurseries. Ultrafiltration eradicated over 99% of R. solanacearum, X. axonopodis, and B. cinerea and 100% of C. candelabrum. The few remaining cells or conidia of R. solanacearum and B. cinerea did not induce disease in irrigated rooted cuttings. Flocculation and fast sand filtration used in physical-chemical treatment completely eliminated C. candelabrum but the other Pathogens were only removed after chlorination of the fil...

Phytotoxins produced by microbial Plant Pathogens.
Natural product reports, 2006Co-Authors: Richard N. StrangeAbstract:Covering: up to the end of 2005 Phytotoxic compounds produced by Plant Pathogens are often crucial determinants of Plant disease. Knowledge of them provides insights into disease syndromes and may be exploited by conventional breeding and biotechnology to obtain resistant crops.
