Context

In Flanders the acreage used for blackberry and raspberry cultivation has increased in recent years. Locally grown fruits are available from May to December. Unfortunately the fruits often have a short shelf life and consequently limited marketability, mainly due to infections by Botrytis cinerea. Growers do not want to take a risk and apply crop protection products according to a calendar schedule to prevent infections, sometimes leading to unnecessary treatments.

In a recently finalized research project ‘Rudisco’, a prediction model was developed in order to more accurately determine risks of infection by B. cinerea. Based on this model, less and more targeted crop treatments can be applied and biological crop protection products are also included in the treatment schedule. The model is not yet usable in practice. Growers of blackberries and raspberries currently perform treatments on average every week and biological crop protection products are hardly used. An optimised and usable model could change this.

Activities

The project consists of five work packages. First, the recently developed prediction model for Botrytis cinerea in blackberry and raspberry will be monitored and validated. Next, the model will be optimised to reduce the number of treatments and to use more biological crop protection products instead of chemical ones. A correlation between weather forecasts and climatic parameters in the different cropping systems will also be investigated to further refine the model. In addition, if necessary, the model will be made more user-friendly for growers. For instance, growers could link their own weather stations or sensors to the application. A cost-benefit analysis will also be carried out.

Activities

Dit project bestaat uit vijf werkpakketten. Eerst wordt het recent ontwikkelde voorspellingsmodel voor Botrytis cinerea bij braam en framboos opgevolgd en gevalideerd. Vervolgens wordt het model geoptimaliseerd om het aantal behandelingen te verminderen en om meer biologische middelen in te zetten in plaats van chemische. Er wordt ook onderzocht of er een correlatie bestaat tussen weersvoorspellingen en klimatologische parameters in de verschillende teeltsystemen, om het model verder te verfijnen. Daarnaast wordt het model, indien nodig, gebruiksvriendelijker gemaakt voor telers. Zo zouden telers hun eigen weerstations of sensoren aan de applicatie kunnen koppelen. Ook zal een kosten-batenanalyse worden uitgevoerd.

1 Practice Abstracts

The objective of the opeational group is to further validate the in a research project developed infection risk model for Botrytis cinerea in blackberry and raspberry, to optimise it if needed and to make it more user-friendly for growers. The operational group also investigates whether a correlation can be established between weather forecasts and climatic conditions in different cultivation systems to predict infection risks even more accurately. The model supports the principle of integrated pest management (IPM) in raspberry and blackberry cultivation; the timing and type of treatments are based on measurements and data analysis. The ultimate goal is to deliver a high-quality product with less residues and to enhance the image of these crops. Based on the model's predictions, the choice of treatments will be determined: biological when infection risk is limited (less than 60% and more than 20%) and chemical only if absolutely necessary (infection risk more than 60%).

De hoofddoelstelling van de operationele groep is om het in het onderzoeksproject ontwikkeld infectierisicomodel voor B. cinerea bij braam en framboos verder te valideren, indien nodig te optimaliseren en gebruiksvriendelijker te maken voor telers. Daarnaast wordt onderzocht of een correlatie gelegd kan worden tussen weersvoorspellingen en klimatologische omstandigheden in verschillende teeltsystemen, om infectierisico’s nog nauwkeuriger te voorspellen. Dit model ondersteunt het principe van geïntegreerde gewasbescherming (IPM) in de teelt van frambozen en bramen, waarbij metingen en data-analyse leidend zijn voor de keuze van de beheersingsstrategie. Het uiteindelijke doel is om een kwalitatief hoogwaardig product met minder residuen te leveren en het imago van versheid en gezondheid van deze teelten te versterken. Op basis van de voorspellingen van het model zal de middelenkeuze bepaald worden, met name, biologisch bij beperkt infectierisico (kleiner dan 60% en groter dan 20%) en alleen chemisch indien absoluut noodzakelijk (infectierisico groter dan 60%).
