# DeciControl: a participative tool to gather & share data regarding biocontrol efficacy

## Context

Biocontrol: a key to reducing the use of chemical pesticides but...

* Unpredictable efficacy of protection in the field

* Efficacy modulated by multiple biotic and abiotic factors (e.g. temperature, humidity, microbiote,...)

* Biocontrol is more complex to use than chemical pesticides

## Research questions

* Could a Decision Support System help minimize the unpredictability of biocontrol efficacy and therefore improve biocontrol deployment ?

* What data would be needed to build such a tool?

* Can scientific knowledge be a sufficient source of information?

## Identification of obstacles to wide adoption of biocontrol for disease management

**Survey of farmers & farm advisors**

* More efficacy benchmarks of biocontrol products from trusted peers

* Better advice on the best biocontrol solution available in their situation

* A simple and clear guideline to use biocontrol solutions in the best way

**Review of scientific & technical literature**

* Abundant published research about mechanisms of action in the lab

* Limited data about efficacy in field conditions

* Scant studies focused on efficacy factors of biocontrol

## Principle of the DeciControl app and content-improvement loop

Insert processed information into the database to improve the content of the app

### Content shared with users

A "product page" for each biocontrol product

* General information on biocontrol products (active substances, known modes of action, officially approved uses)

* Factors influencing the protective efficacy

* Synthesis of feedback from biocontrol users under commercial conditions

<figure><img src="image_9.png" /></figure>

### Scientific and technical literature

* Publicly available and unpublished data on biocontrol efficacy

* Regulatory information about registered biocontrol products

### Feedback from users

* Possibility to provide feedback on biocontrol efficacy in the field + context data (cropping practices & conditions of biocontrol application)

* Input of data through easy-to-use forms integrated in the app

Users (advisors, farmers)

Provide feedback on field experience (Text and photos)

Consult to realize an optimized choice of biocontrol solution based on user's context
