Priming the future for healthy plants

By | | No Comments

The Institute for Sustainable food hosts the International Organisation for Biological Control (IOBC)-WPRS PR-IR 2021: Priming the Future for Healthy Plants

6 – 9 September 2021

About the conference

Pleased to announce the PR-IR meeting, organised on behalf of the ‘Induced Resistance in Plants Against Insects and Diseases’ working group of the International Organisation for Biological Control. 2020 has been declared “International Year of Plant Health” by the United Nations and this meeting celebrates this significant recognition of the importance of plant health within sustainable agriculture.

IOBC PR-IR meetings provide a specialist forum for researchers on plant responses to microbial pathogens and invertebrate herbivores to exchange information and discuss the latest ideas on induced resistance. The focus will be on fundamental science, but with a view to the potential to exploit new understanding for crop protection. The meeting will cover a broad range of topics, from the mechanisms for initial perception of pests and pathogens and signalling pathways for induced resistance, to the ways in which multitrophic interactions with microbiomes and natural enemies influence the relationships between plants and their pests and pathogens. In addition to a range of invited expert speakers there will be opportunities for delegates to present talks and posters.

How plants produce defensive toxins without harming themselves

By | News, Plant Health, Plant Science

Plants produce toxic substances to defend themselves against herbivores. In a new study, scientists were able to describe in detail the biosynthesis and exact mode of action of an important group of defensive substances, the diterpene glycosides, in wild tobacco plants. Diterpene glycosides allow plants to fend off herbivores. The study shows that these plant chemicals attack certain parts of the cell membrane.

After 100 years, plant pathologists revisit fire blight hypothesis

By | News, Plant Health, Plant Science

Historically credited as being the first bacterium ever characterized as a plant pathogen, fire blight is a bacterial disease that leads to significant losses of pear and apple. The role of insects in the spread of this disease has been long studied. In a new study, plant pathologists take a hypothesis that has been more or less ignored for 100 years and provided support for its validity.

Wheat disease common to South America jumps to Africa

By | Agriculture, News, Plant Health, Plant Science, Policy

A deadly wheat disease common to Asia and South America has been identified in Africa for the first time, raising fears of potential spread to wheat crops across the continent. Researchers say that the fast-acting and devastating fungal disease known as wheat blast was first spotted in Africa in the Zambian rainfed wheat production system in the 2017-2018 crop cycle.

​​​​Short-term moisture removal can eliminate downy mildew of spinach

By | Agriculture, Fruits and Vegetables, News, Plant Health

Downy mildew is the biggest threat to spinach production around the world. While the pathogen has a short life cycle (approximately a week), it can produce millions of spores during the spinach growing season. Overhead sprinkler irrigation systems and dew formation on cool nights leads to more moisture, which enables these spores to infect the spinach.
