Objectives:

This research activity will develop new technologies for crop protection based on the combination of detection and monitoring methods at the macro scale (whole field) and micro scale level (certain positions in the field) with decision engines and innovative crop protection solutions.

These technologies will be included in innovative IPM solutions developed in the different cropping systems. It will develop:

- Airborne sampling and optical sensing methods for macro scale mapping;

- Molecular based diagnostic tools for micro scale identification and monitoring;

- New generation of generic decision engine for weed control;

- Mating disruption solutions for pest control in protected vegetables and grapevine;

- Precise crop protection products application based on canopy density sensing.

Approach:

This research activity will develop new technologies for crop protection based on the combination of detection and monitoring methods at the macro scale (whole field) and micro scale level (certain positions in the field) with decision engines and innovative crop protection solutions. Innovative crop protection solutions will include mating disruption technologies both for protected vegetables with controlled use of pheromones and for grapevine with vibration transducer technologies, and precision spraying techniques to apply adequate amounts of crop protection products, minimizing the risks of residue and environmental load.

Research will be conducted on physical and information technologies. Both complement each other to enhance the incorporation into the renewed IPM schemes into the different cropping systems. Physical technologies are required for sensing, monitoring, and actual control measures. The combination with information technologies like forecasting and modelling are required to face actual climate change and related faster changes in cropping systems. Interaction with the different cropping systems activities will allow including emerging technologies in the ex-ante assessment as valuable improvements to the current IPM solutions, and evaluating in real conditions (on-station and/or on-farm) the developed technologies within these work-packages. When monitoring is realized these quantitative data are coupled to damage thresholds that are provided by WP3 for maize and also by the models for airborne diseases (see Pest evolution and enhancement of the durability of IPM solutions).

Integration of NGS and BioTrove platform data for multipathogen monitoring
Micro scale monitoring of several pathogens simultaneously is expected to improve decision making and forecasting based on the occurrence and spread of pathogens at different geographical scales. This kind of monitoring should also enable the monitoring of pathogen populations change as a result of climate change and management practices. It will therefore develop platforms for multi-pathogen quantitative monitoring based on molecular diagnostic tools.
