Can Decision Support Systems Help Improve the Sustainable Use of Fungicides in Wheat?

چکیده

Wheat is one of the most economically important field crops worldwide. Foliar diseases are a major threat to wheat productivity and primarily managed by implementing less susceptible cultivars using fungicides. With “Farm Fork” strategy under consideration European Union reduce pesticide usage 50% 2030, this elucidates importance utilizing decision support systems (DSS) optimize fungicide applications. Therefore, three DSSs different origins, namely IPM-Wheat Model Schleswig-Holstein (scientific), ISIP system (federal), xarvio© FIELD MANAGER (commercial), were analysed maritime climate conditions at locations in high input area cultivation northern Germany from 2019 2021. Fungicide efficacy was evaluated for yield as well management prevalent pathogens (Septoria tritici blotch, glume tan spot, powdery mildew, stripe rust, leaf rust) on two commercially available (highly moderately susceptible). Compared stage-oriented standard system, no significant decrease observed both cultivars, despite up reduction use through DSSs. This attributed an optimized timing applications, which resulted slightly lower but still tolerable disease suppression compared system. In conclusion, minor severities often overestimated, can help improve sustainability pesticides general.

Use Semantic Decision Tables to Improve Meaning Evolution Support Systems

Meaning Evolution Support Systems have been recently introduced as a real-time, scalable, community-based cooperative systems to support the ontology evolution. In this paper, we intend to address the problems of accuracy and effectiveness by using Semantic Decision Tables. A Semantic Decision Table separates general decision rules from the processes, bootstraps policies and template dependenci...

Modeling Sustainable Product Lifecycle Decision Support Systems

Sustainable product lifecycle systems are attracting increasing attention because of cost competition, resource constraints and environmental issues. Short lifecycle products, such as consumer and defense electronics, are of particular concern. We formulate a closed-loop supply chain with Stochastic Dynamic Programming method. By applying the concept of a sustainable product lifecycle, guidelin...

Can Stated Preference Valuations Help Improve Environmental Decision Making?

Decisions about preservation, protection, or development of environmental “commodities” like ground water, atmospheric visibility, open space, wildlife, wetlands, and forests are often made without good information about the value of preservation relative to the cost. Clearly, the economic cost of preservation is often substantial. The cost of preserving wildlife habitat, for example, often tot...
