CP6 & CP7: Lab-to-field upscaling of biologicals and AI-assisted pathogen monitoring
In order to realize an ecological and economical agriculture, efficient use of resources in plant protection is necessary. The detection of plant diseases in the field is complex, as fungi grow on or in plant tissue and are not visible to the bare eye at the beginning of an infection (Hallmann et al. 2019). Early detection is essential in order to minimize yield losses through rapid and appropriate countermeasures.
This also includes the use of biological antagonists, with the potential to replace chemical plant protection products in the medium to long term without the problem of chemical residues or the development of drug resistances. To achieve this, it is necessary to quantify the pathogens, also using AI-based remote sensing, in the plant population at an early stage and to initiate control measures promptly. However, further research into the development of new biological antagonists that improve efficacy in the field through innovative formulations is required for practical use in the field. The right time, type and location of application also have a major influence on the effectiveness of biological control (Bejarano & Puopolo, 2020).
The aim of the joint research project for the second funding period is to utilize the successful application of specifically formulated biological control agents with the aid of AI-supported pathogen monitoring for the further development of an innovative plant protection system in a NocsPS cultivation system. This should enable the early detection of stress factors and the timely initiation of appropriate countermeasures.
In order to achieve greater flexibility and effectiveness of the biological antagonists, it is planned to compare different application methods (foliar treatment, soil application, seed dressing) and to test various formulations.
The work program of the Phytopathology and Artificial Intelligence in Agricultural Engineering departments is divided into two overarching work packages:
WP1: Establishment of preparations with biological antagonists for the control of ear fusarium and white stem borer
- Clarification of further indirect and direct modes of action of biological antagonists, as well as their performance under field conditions (rain, UV radiation)
- Optimization of application methods and locations using AI-based analyses
WP2: Development of methods for AI-based plant pathogen detection in soy and wheat
- Development of an automated data acquisition under controlled conditions in the greenhouse of multi-modal spectral images for the training of the targeted robust deep learning models
- Working out the continuous need for optimization in order to continually incorporate suitable adaptations from the rapidly developing state of AI research.
- Investigation of the transferability of the developed AI methods from the lab-scale, over simulated conditions in the green house, up to real field conditions in order to ensure later feasibility in practice.
