‘Devastating’ fungal infections wiping out crops and threatening global food security, experts warn

By | Agriculture, News, Plant Health

Scientists have warned of the ‘devastating’ impact that fungal disease in crops will have on global food supply unless agencies across the world come together to find new ways to combat infection. Worldwide, growers lose between 10 and 23 per cent of their crops to fungal infection each year, despite widespread use of antifungals. An additional 10-20 per cent is lost post harvest. Academics predict those figures will worsen as global warming means fungal infections are steadily moving polewards, meaning more countries are likely to see a higher prevalence of fungal infections damaging harvests.

Understanding the long-term impact of climate change on Indian crops

By | Agriculture, Climate change, News

Over the past few decades, it has become obvious that climate change, and consequent extreme weather events, can wreak havoc on crop yields. Concerningly, there is a large disparity in agricultural vulnerability between developed and developing countries. In a new study, researchers have looked at major food grains in India to understand the long- and short-term effects of climate change on crop yields.

Understanding crop pest evolution may boost biocontrol

By | Agriculture, News, Plant Health

Researchers have reconstructed the evolutionary history of a highly specific olfactory receptor in the Egyptian cotton leafworm, a crop pest. This receptor plays an essential role in moth reproduction because it allows males to recognise the female sex pheromone. The scientists determined that the receptor appeared around 7 million years ago and that eight amino acids underlie receptor-pheromone binding. Their findings can guide the development of biocontrol strategies directed against this pest.

Impact of fall armyworm pest in Sub-Saharan Africa worsened by COVID-19, study reveals

By | Agriculture, News, Plant Health

The impact of the fall armyworm pest on maize crops and communities in Sub-Saharan Africa were worsened by the COVID-19 pandemic, according to paper. Drawing upon recent empirical literature on the pest since it was first reported in Africa in 2016, scientists from Nairobi, Kenya, highlighted how it was responsible for up to 58% of maize losses worth up to US $9.4 billion.

Early crop plants were more easily ‘tamed

By | Agriculture, News, Plant Science, Research

Did humans favor certain wild plants for domestication because they were more easily “tamed”? New research calls for a reappraisal of the process of plant domestication, based on almost a decade of observations and experiments. The behavior of erect knotweed, a buckwheat relative, has paleoethnobotanists completely reassessing our understanding of plant domestication.

Study measures early detection of aging in seeds

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

Aging is a part of life, and plants are no exception. The life cycle of a plant is felt in genebanks that store plant materials, such as seeds. Plant materials in genebanks may be accessed by farmers, researchers, conservationists, and others for breeding. But for a genebank to provide useful germplasm to growers, the seeds stored there must be alive when harvested. And as the stored seeds start to age, fewer and fewer of them live long enough to germinate. So, genebanks must continuously monitor stored seeds to ensure they haven’t aged beyond their ‘expiration date’ and lose ability to germinate.
