Integrated Plant Protection

Last changed: 07 February 2020

Integrated Pest Management (IPM) has been mandatory for farmers in EU countries since 2014, yet we still lack a lot of scientific knowledge to help us use IPM effectively in many European crops. Therefore, we at the Integrated Plant Protection Unit aim to generate knowledge towards the development of sustainable pest and disease management solutions based on conceptual theory and empirical eco-evolutionary, molecular and genetic data that can meet the needs of current and evolving plant production systems.

What is IPM?

Integrated Pest Management (IPM) as defined by the EU means:

careful consideration of all available plant protection methods and subsequent integration of appropriate measures that discourage the development of populations of harmful organisms and keep the use of plant protection products and other forms of intervention to levels that are economically and ecologically justified and reduce or minimise risks to human health and the environment. ‘Integrated pest management’ emphasises the growth of a healthy crop with the least possible disruption to agro- ecosystems and encourages natural pest control mechanisms.”

What do we do in the Integrated Plant Protection Unit?

We work on the Science of IPM!

IPM is a broad multidisciplinary subject and we focus on two interconnected subdivisions within IPM using a variety of methods and approaches:

Unit strategy
Subdivisions within the unit of Integrated Plant Protection

Integrated disease management projects

Molecular analysis of oomycete cell wall biology in Phytophthora infestans to discover new targets for potato late blight disease control

SSF funded 2015-2020

In this project we are interested in fundamental oomycete biology and development. We also hope to identify developmental checkpoints that could be targets for new drugs to stop oomycete growth.

Exploiting the biological activity, ecology, genomics and effector repertoire of mycoparasitic oomycetes for disease control

SSF and SciLifeLab funded 2015-2020; Crafoord Foundation funded, 2017-2018; Carl Tryggers foundation funded, 2017-2018 and 2020; EU funded (PROTECTA MSCA-ITN 2018-2023)

P. oligandrum

In this project we are interested in further developing P. oligandrum for use as a BCA. To do this, we study the biology of P. oligandrum, the pathogenicity determinants produced during host colonization and particularly the development, germination and dormancy determinants of oospores. Improving oospore germination should allow us to improve the use of P. oligandrum. We also study the effects of P. oligandrum on the rhizosphere microbiome, secondary metabolite production, and microbe-microbe interactions at the molecular, cytological and genetic level. We also carry out comparative genomics to identity unique and conserved genetic determinants of mycoparasites compared to plant and insect pathogens in the oomycetes. Finally, we assess the ability of P. oligandrum to control various diseases in field trials.

Comparative molecular analysis of the early blight fungus (Alternaria solani) and the late blight oomycete (Phytophthora infestans) and identification of core effectors as new targets for resistance breeding strategies

Formas funded 2016-2020

In this project, we are studying pathogen biology in the field and competition or synergism between multiple pathogens on the same host plant and the implications of these interactions for disease control and fungicide resistance.
