Carrot rust fly is an insect that can cause damage to carrots and some other crops. The first generation of adult carrot fly emerge from pupae in the soil in the spring, and lay eggs close to the base of vulnerable crops. Larvae initially feed at the surface, then tunnel into the tap root. Adults emerge mid-July and can lead to a second generation. Treatments may need to be applied soon after adults arrive in the crop, before larvae tunnel into the crop roots. The DSS determines the start of the flight period for the 1st generation of carrot rust fly based on accumulated degree-days (260 day-degrees) over a base temperature of 5°C. The model uses daily air temperature; the default starting day is 1 March. Please adapt if necessary for your country. Be aware that in areas with field covers (plastic, single or double non-woven covers, etc.) with early crops the preceding season (either on the current field or neighbouring fields), the flight period can start earlier than predicted due to higher soil temperature under the covers. The DSS shows accumulated day degrees after 1 March and thresholds for the start of the flight period and the threshold for the peak of the flight period. When the first flight is expected, placing yellow sticky traps in the field is recommended to monitor if the flies indeed are present in the field. The DSS was developed by Luke, Finland, and is considered applicable, but not yet validated, in the United Kingdom, Belgium, The Netherlands, France, Germany, Luxembourg and Denmark.

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.

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).
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.
