Agricultural Super Ducks
Agricultural super ducks? You may think that the entire phrase is flawed. Ducks waddle around in parks, not on farms. You probably have never thought of them as being particularly ‘super’ as they paddle around the park pond, searching for scraps of bread. However, you’d be mistaken, as I was, for the humble duck is…

Speedy crop breeding to help Japanese rice growers
The devastating tsunami that hit northeastern parts of Japan last March left thousands of acres of farmland damaged by saltwater. Much of this agricultural land was paddy fields, which were left with up to 25 cm of sand and mud deposited and highly saline conditions resulting from evaporation of the seawater. Scientists from the Sainsbury…

India’s Food Security Challenges
Agriculture is very important to India, employing 55% of its population and providing 16.5% of its annual GDP. The industry as a whole is worth US$ 17.5 million alone in exports. However, it’s not all plain sailing, with low productivity and regional groundwater depletion currently threatening Indian agriculture. Climate change and the demands of an…
Quorum-sensing disruption, a new tool for disease management?
A new study by Chernin et al. has found that volatile organic compounds produced by certain Plant Growth Promoting Rhizobacteria (PGPR) can disrupt bacterial cell-cell communication (quorum sensing) in a number of plant pathogens including Agrobacterium, Chromobacterium, Pectobacterium and Pseudomonas. Application of PGPRs could in future be used as a new disease management strategy.
Why we should all be batty about agriculture
Bats are perhaps one of the best kept secrets of agricultural success. As nocturnal fliers they are often ‘out of sight, out of mind’, but insectivorous bats (Chiroptera) provide us with a natural, eco-friendly, and free pest control solution, saving North America alone an estimated $3.7 billion every year. Good news then? Not so much…

Stopping Striga before it’s started
Striga, or witchweed, is the main weed affecting many cereals including rice, maize, sorghum and millet. One species, Striga hermonthica, is responsible for more crop loss in Africa than any other individual species of weed. Striga is a hemi-parasitic weed; its roots latch onto the roots of its host (e.g. a crop plant such as…
