Research need from Focus Group: optimisation of cover crops
biological pest control
non-chemical pest control
Pest / disease control
This is the problem:
This need for research has been identified in FG 33 on "pests and diseases of the olive tree". If you want to know more about it check the final report of the Focus Group.
There are still knowledge gaps concerning selection of species composition for different agro-climatic areas and the most suitable plant species to promote functional diversity. It is also necessary to optimie the agronomic practices applied to the management of the covers to favor their efficiency, establishment, and avoid competition by water with the olive tree. Finally, it is needed to estimate cost/feasibility of cover crop establishment/improvement and the associated benefits (ecosystem services) provided after its implementation.
