Wintering geese and swans foraging on unharvested sugar beets: an emerging problem
Farmers in south-east Denmark experience increasing problems with foraging barnacle geese on their crops, particularly affecting winter wheat, seed grass, and winter rape. Sugar beet waste is often exploited by geese and swans, and in recent years barnacle geese have adapted to foraging on unharvested sugar beet fields as well. Sugar beet biomass measurements and bird counts show that geese and swans cause damage to unharvested sugar beets. Economic loss caused by geese and swans in eight surveyed sugar beet fields was estimated at less than 1 % of the fields’ value. Both economic loss and area damaged were correlated with abundances of geese and swans. In total, 10 % of the sugar beet fields in the study area were utilized by geese and swans before harvest. Hence, foraging on unharvested sugar beet by geese and swans is not considered a widespread problem, but there are indications that the phenomenon is increasing. Particularly barnacle geese may become a more serious problem due to their occurrence in large flocks and high degree of mobility.
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.
