Objectives:

Objectives of this research activity are to identify factors that disrupt pest and disease infestations and provide the basis for novel crop protection methods.

Specific objectives are to:

1. Assess the potential of selected combinations of defence- and priming-inducing agents to enhance the effectiveness of natural defence in tomato and wheat

2. Develop biocontrol strategies for use against plant pathogens

3. Develop biocontrol strategies for use against insect pests

4. Identify natural products that could function as biopesticides It will provide alternatives to pesticides to control pest/microbe populations in an integrated approach to pest and disease control.

Approach:

This research activity will identify factors that can be used to control pest and disease infestations in order to develop innovative crop protection methods including :

1) novel products to induce /prime plant defence,

2) biocontrol agents to combat plant pathogens,

3) natural enemies to combat insect pests, and

4) natural products as biopesticides.

Research will be conducted at a range of levels from molecular to whole organism to community or field level. Natural products with a direct effect against pests/microbes or their pathogenic behaviour as well as those providing indirect defence by attracting natural enemies of pests or priming plant defence will be investigated. Biocontrol agents will be evaluated in laboratory bioassays and field plot trials to determine which show the most potential for use in crop protection. The knowledge of plant defence and interactions between pests and natural enemies gained in this research activity will inform pest management practise and the development of bio-products or green products will supply the toolbox of the cropping systems activities.

All four tasks will be elaborated in close interaction with all the "CRopping systems" activities to ensure that the intermediate ans end-results of this research acitvity are implemented in the design-assessment-adjustment cycle of innovative IPM solutions.

Description of Deliverables:

More efficient strains of parasitoids and protocols for certification for use against insect pest
Characterization of insect parasitoids available commercially in order to certify them from a taxonomical and biological point of view. Exemple of Tuta absoluta  and of the mealybug pests of grapewine.
