Continental controls needed to maintain fightback against tree diseases

Tighter controls on timber and plant movements into Europe are necessary to prevent further disastrous effects of plant diseases, a new study of the ash dieback pathogen advises.

The call to action follows detailed investigations carried out in British woodlands into the population makeup of the Hymenoscyphus fraxineus fungus that causes ash dieback.

Study offers guidance on how to protect olive trees from being ravaged by deadly pathogen

Expert ecologists at the UK-based Centre for Ecology & Hydrology (CEH) have devised a scientific model which could help predict the spread of the deadly Xylella fastidiosa which is threatening to destroy Europe’s olive trees.

The CEH scientists have created a model which is able to qualitatively and quantitatively predict how the deadly bacterial pathogen may spread as well as offer guidance on how buffer zones should be arranged to protect uninfected olive trees.

How to be a successful pest: lessons from the green peach aphid

© Earlham InstituteUK scientists, in collaboration with groups in Europe and the US, have discovered why the green peach aphid (Myzus persicae) is one of the most destructive pests to many of our most important crops. Their research will inform industry and research programmes to support pest control and aid global food security.

Challenges of breeding ‘VIPeas’

The small but mighty chickpea packs a dietary and environmental punch. They are an important source of nutrition, especially protein, for billions of people across the world. Additionally, bacteria that live in root nodules of chickpea plants pull in atmospheric nitrogen, increasing soil productivity.

But breeding new varieties of chickpeas with desirable traits – such as increased resistance to diseases and pests – is difficult. In fact, it is “tedious and inefficient,” says Thomas Stefaniak, a researcher at North Dakota State University (USA).

UK fruit consortium to deliver next generation of crop scientists

An industry consortium, led by Berry Gardens Growers Ltd and NIAB EMR, has won a BBSRC collaborative training partnership (CTP) award to provide a £1.9 million postgraduate programme for scientific research on fruit crops.
