Abstract

Field surveys were conducted in Wisconsin in 2021 and 2022 to assess the prevalence of Potyvirus iriseverum (previously Iris severe mosaic virus, ISMV) in field grown irises and wild populations in surrounding areas. A total of 460 samples were collected from 19 sites in 10 Wisconsin counties. The plants sampled included field-grown Iris x germanica (bearded iris) and Iris sibirica (Siberian iris), and naturally occurring Iris versicolor (blue flag). The survey revealed notable differences in ISMV occurrence among iris species. Cultivated bearded iris exhibited a high incidence rate of 81 % in 2021 and 73 % in 2022. Interestingly, 74 % of bearded iris without visible symptoms tested positive for ISMV by DAS-ELISA. In contrast, other species, such as the native blue flag, found in neighboring wetlands, and Siberian iris, exclusively tested negative for the virus. This survey highlights the high prevalence of ISMV in field-grown bearded iris in Wisconsin. In addition, it indicates that diagnostics for ISMV should not rely on detection based solely on visual symptoms.

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
