Résumé : | This compendium brings together information on the diseases of an important floriculture crop group, the greenhouse-grown, flowering potted plants. In the 1993 U.S. Department of Agriculture Floriculture Crops Summary, flowering potted crops in the United States (including potted geraniums) were valued at $808 million wholesale. Poinsettias and geraniums are currently the dominant flowering potted-plant crops in the United States. A greater diversity and volume of flowering potted plants is marketed in Europe than in the United States, where sales are closely associated with major holidays. Disease prevention and management are important concerns of potted-plant growers. Plant diseases cause crop losses directly through plant mortality and frequently cause aesthetic injury that reduces crop quality and value. In the course of their production from seed or cuttings to finished hanging basket or pot, plants are often moved from one greenhouse operation to another, sometimes even internationally. This practice creates opportunities for the introduction of plant pathogens from one greenhouse operation to another. Greenhouse-to-greenhouse exchange of plants also facilitates the exchange of pesticide-resistant diseases and insects throughout the greenhouse industry worldwide. Because many different potted-plant species are typically produced within one operation, it is especially challenging for the grower to be thoroughly informed of all the potential disease problems. Regular monitoring should be conducted with full awareness of the diseases important to each crop. Anticipating likely problems also allows growers to take preventive cultural approaches to disease management. Prevention strategies are much more effective than responsive treatments after symptoms have developed. Once symptoms are apparent, prompt and accurate diagnosis is essential so that appropriate disease-control measures can be instituted without delay. |
