“The main constituents of the cell wall, e.g. crude fiber, ADF, NDF and lignin, were analysed in 10 important varieties of grassland plants. The results of 555 analysed samples give a better knowledge of the changes with regard to the content of cell wall constituents during the growing season. Within the same plant variety and depending on the age and the stage of development, the content of all 4 cell wall constituents changed in a similar way. The relation between the content of those constituents and the age as well as the stage of development is stronger during the first growth than during the subsequent growths. During the first growth and within the group of grasses, meadow foxtail has the highest content of cell wall constituents, whereas cocksfoot with the age has the fastest increase of that content. Within the group of legumes, we noticed the highest content and its biggest increase with lucerne. The comparison of the changes in the crude fiber content in relation to the stage of development shows a reasonable similarity with the values in the “”Swiss Green Book””. The disadvantage of the “”Green Book”” is that it does not make any difference between ist growth and regrowths.”
Herbicide-resistant weeds are a growing problem throughout the world. Monitoring herbicide resistance in Switzerland allows us to understand the mechanisms behind it and to better manage the use of herbicides.
Agroscope compared crop protection strategies in apple production. Reducing the use of plant-protection products lowered the local ecotoxological risks, but resulted in trade-offs between environmental and economic performance.
Bacillus thuringiensis (Bt) bacterium proteins protect Bt maize from being fed on by specific insects. A new, systematic analysis of international field data confirms that non-target organisms in Bt maize are largely spared.
