Here’s a taste of some of the latest stories about plant health, including early reports on the damage caused by Tropical Cyclone Pam in Vanuatu, the first carbon neutral banana farm recognised in Costa Rica and training for Citrus farmers in Ghana on the use of technology to increase yields.
A new video from the International Atomic Energy Agency shows how radiation can be used to make mutations in crop plant DNA. This process applied to a large number of seeds creates a selection of mutants that can be tested to see how well they perform as crops. Research in Peru has led to the development of a new barley variety, which has benefited farmers with its high yield. -!>
New research at Washington State University shows that barley plants are able to recognise stem rust spores (Puccinia graminis) and begin to activate their plant defences within just 5 minutes of the spore touching the leaf surface. This goes against the previously held view that pathogens had to penetrate a plant in order to trigger the internal plant defence mechanisms. This new knowledge could revolutionise the way that farmers deal with pathogens of cereal crops such as stem rust.
