Green Impulse



Innovative agricultural inputs

GREEN IMPULSE is a start-up in biotechnology that provides innovative solutions for agriculture. It offers technical and scientific expertise in the field of plant health and uses technology patent-protected by the University of Angers.

The purpose of GREEN IMPULSE is to develop innovative agricultural bio-inputs in order to facilitate the decrease and, eventually, replacement of conventional phytosanitary products usage. Our ultimate goal is to halt the current dependency on pesticides in agriculture.

Becoming the European Leader in biocontrol Synergists*

Fungi are responsible for nearly half of the diseases known to date in cultivated plants. The fight against these fungal diseases is mainly achieved by the use of phytosanitary products (fungicides). However, we can no longer rely on the sole use of pesticides, crop protection must evolve towards new strategies.

In this context,GREEN IMPULSE is committed to the development of new strategiesin the fight against plant pathogenic fungi to enhance performance and allow the rapid deployment of alternatives to fungicides, especially bio-control agents.

A unique and innovative concept

Our Synergists Technology is based on a fundamentally different approach to Pesticides. The fungicides used in crop treatment aim to directly attack and kill their targets the pathogenic fungi. In our case, the Synergists Technology weakens the pathogenic fungi to make them more sensitive and vulnerable to the natural defenses of plants. Thus, the treatment products associated with our Synergists Technology, such as Plant Defenses Stimulators (SDP), are more effective as they hinder the development of pathogenic fungi on plants substantially.

* Synergiste : A substance or preparation that enhances the activity of the active substance-(s) present in the plant protection product-(s).

Largely dominated by pesticides, the plant protection market in agriculture represents 50 billion euro worldwide.

In the last 20 years, new more environmentally-friendly solutions called "bio-control agents" have been attempting to evolve in this market. Bio-control agents generate a global sales revenue of 2.8 billion euro, representing 5% of the global plant protection products market. This market is estimated to reach a market value of 9 billion euro by 2025, after a steady sales growth of 15% per year. In Europe, bio-control agents generate a revenue of 600 million euro, including 140 million euro in France alone. Therefore, it is a fast-growing market which could eventually be considered as an alternative to conventional plant protection products and capture their value increasingly.

Pathogens have developed adaptive measures to plant’s natural defenses. Our strategy aims to disrupt these adaptive behaviors to increase their vulnerability to plant defense mechanisms.
Our technology is based on the action of Synergists molecules inhibiting the adaptive responses of the main pathogenic fungi in crops. The molecules resourced by GREEN IMPULSE stem from natural plant extracts and are complementary to the market’s SDP bio-control agents.

Our ambition is to meet the expectations of arborists, winegrowers and farmers with the major challenges focusing on downy mildew in grapes, apple scab and wheat septoria.
