Control

The use of antibiotics is not permitted in Switzerland; moreover, no other medication exists to combat European foul brood. Hives with symptoms must therefore be destroyed in order to limit the outbreak, and the contaminated material must be sanitised. Since prevention is the best cure, early detection is desirable. Numerous studies have been undertaken and documents have been created at the Swiss Bee Research Centre and elsewhere to draw the attention of beekeepers to these problems and inform them about the causes and the control measures to be implemented.

Abstract:

The Swiss Soil Monitoring Network NABO records the long-term evolution of soil organic carbon (SOC) over extended periods. Two different analytical methods were used to determine SOC, namely wet oxidation (WO) and retitration of potassium dichromate (Swiss Standard Method) and dry combustion (DC) with a CN-analyser and subtraction of inorganic carbon. Generally, the WO method generates lower SOC contents than the DC method. Therefore, SOC contents by WO must be adapted to the level of the DC method to avoid distortion of temporal evolutions. For NABO soils, conversion factors between the two methods ranged from 1.01 to 1.42 with a median of 1.18. Due to the large variation between sites, site-specific conversion factors should be used, whenever possible.
