Reduction and efficient use of phytosanitary treatments for the black spot of the pear tree by improving the calculation accuracy of the "BSPCast" model with ultra-low-cost leaf wetting sensors on plots".

The project starts from the need that there is a wide margin for improvement in the application of an efficient number of phytosanitary treatments if the precision of the calculation of the "BSPCast" model is improved on the basis of having wetting measures associated with each plot since specific and personalised exits could be obtained for each of these.


The general objective of the project is the reduction of phytosanitary treatments against the black spot of the pear tree using as reference the "risk index" of the "BSPcast" model with particularised wetting data in specific plots.

The relevance of the proposal lies in the fact that it is focused on one product, the pear, which is profitable for La Rioja (with 2500 ha) and for a specific disease (black spot) but this project, its methodology and the objectives to be achieved (reduction of phytosanitary products, increase of productivity/hectare and reduction of emissions) can be extrapolated to any crop where leaf humectation is a relevant factor for the development of the disease, such as mildew in the vineyard, mildew in the potato and mottling in the apple tree.


In order to measure the humectation in leaf ENCORELAB will develop five prototypes of an electronic system and a small low-cost sensor to measure the humectation, to send the information to a server in which, together with other parameters, the risk of the disease is calculated. At the same time, the application will be developed to geolocate the sensor and offer the black spot risk information calculated for the plot where the sensor is installed.


The project has been promoted by the Agroclimatic Information Service of La Rioja, ENCORE LAB, Rincón de Soto Pears Designation of Origin and ARAG-ASAJA.

It is a project co-financed by the Ministry of Agriculture and Fisheries, Food and Environment, the Rural Development Programme (RDP) of the Government of La Rioja and the European Agricultural Fund for Rural Development.
