| The Colorado potato beetle (Leptinotasara decemlineata Say) is one of the most important pests on potatoes (Solanum tuberosum). In the present study, we compared the efficacy of three biological insecticides – Neem (NeemAzal-T/S), pyrethrum/rapeseed oil (Spruzit Neu) and Bacillus thuringiensis var. tenebrionis (Novodor FC) – against this pest in field trials conducted from 2005 to 2007. The combined and temporarily shifted application of neem and B.t.t. reduced significantly the number of beetle larvae and the percentage of defoliation due to larval feeding, and increased the potato yield considerably. The SIMLEP3 forecasting model is useful for determining the optimal timing of the treatment. Pyrethrum/rapeseed oil did not lead to a significant reduction... |

| The goal of this work was to develop a concept for the ecological and productive agricultural use of the private sites and the surrounding public areas, protected by nature conservation, on the inland island “Schöninsel” in Mecklenburg-Western-Pomerania. The challenge was to harmonize the interests of the property owner as well as concerned public groups, and to adjust the concept to requirements of nature conversation and natural and socioeconomic site factors. In all planning phases, permaculture principles and design methods were used. Practical planning was guided by the following goals: harmonization of aesthetic aspects and usefulness, preservation and enhancement of biodiversity, nature conservation, and raising awareness by environmental education.... |
