Factsheet DSS Saddle gall midge in cereals
Saddle gall midge (Haplodiplosis marginata) is a sporadic pest of cereals, which usually persists at low population levels. Yield loss can be caused by constricted vascular supply to the ears as a result of larval feeding and by lodging of gall-weakened stems in high winds. Pupae overwinter in the soil, from which adults emerge in the spring to lay eggs on vulnerable crops. Damage is caused by subsequent larval feeding. Once larvae have crawled under the leaf sheath, they cannot be controlled using contact treatments (e.g. insecticides). Control with help of DSS Saddle gall midge model on platform.ipmdecisions.net. This DSS indicates the best time to monitor crops for infestations (start of emergence). If abundance is high, and non-chemical management options are unlikely to achieve adequate control, treatment needs to be applied before, or soon after oviposition. DSS assumes the earliest date of emergence of saddle gall midge to be after 500 day degrees. User must interpret the reported risk against the vulnerability of the crop growth stage on farm and undertake in field monitoring to assess the abundance of emerging adults. The DSS starts on the date of first rainfall on or after the 1st March and ends at the end of July. The DSS uses accumulative daily temperature (500-degree days above 0 degrees) and rainfall. The DSS predicts proportion of cumulative emergence of the saddle gall midge, the associated risk and recommended action. This DSS was adapted from work carried out in the UK, and is considered applicable, but not yet validated in, Belgium, Luxembourg, Netherlands, France, Germany, and Denmark.

A Bio-inspired Multilayer Drainage System
Agricultural run-off and subsurface drainage tiles transport a significant amount of nitrogen and phosphorus leached after fertilization. alchemia-nova GmbH in collaboration with University of Natural Resources and Life Sciences, Vienna developed two multi-layer vertical filter systems to address the agricultural run-off issue, which has been installed on the slope of an agricultural field in Mistelbach, Austria. While another multi-layer addressing subsurface drainage water is implemented in Gleisdorf, Austria. The goal is to develop a drainage filter system to retain water and nutrients. Both multi-layer filter systems contain biochar and other substrates with adsorption properties of nutrients (nitrogen, phosphorus). The filter system can be of practical use if an excess of nutrients being washed out is of concern in the fields of the practitioner by keeping the surrounding waters clean. This approach may result in economic value by re-using the saturated biochar as fertilizer and improving the soil structure, thus increasing long-term soil fertility.

NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY
This project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 858735This project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 858735. FACTSHEET NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY Key information Functionalized nanocellulose membranes can take up nitrate and phosphate. These membranes can be put in a water treatment unit. As the membranes are biobased, degradable materials, they can after use be added to the soil, thus returning the leached nutrients back for their original purpose providing fertilizers (nutrient recycling).
Environmental monitoring within greenhouse crops using wireless sensors
Because variables such as temperature and humidity have a profound effect on the activity of crop pests, diseases and natural enemies, the ability to monitor environmental conditions within a crop has always been important for crop protection.
