Virus turns deadly fungus from foe to friend in plants

Researchers have discovered that a fungal virus (also called a mycovirus) can convert deadly fungal pathogens into beneficial fungus in rapeseed plants. Once transformed, the fungus boosts the plant's immune system, making ...

Turned-down temperatures boost crops' penchant for production

Drought and heat put stress on plants and reduce grain yield. For some farmers, irrigation is the answer. Many of us assume the practice boosts crop yields by delivering soil water, but it turns out irrigation's cooling effect ...

New pathogen threatens fennel yield in Italy

A new fennel fungal disease caused by a new genus and species—Ochraceocephala foeniculi, was observed for the first time in 2017 on 5% of the "Apollo" fennel cultivar grown in the sampled localities in Catania province, ...

Novel watermelon rootstock knocks out disease and pests

A new watermelon line, developed by Agricultural Research Service (ARS) and Clemson University scientists, gets to the root of the problem of a major disease and pest of watermelon crops in the southern United States.

The dirt on soil loss from the Midwest floods

As devastating images of the 2019 Midwest floods fade from view, an insidious and longer-term problem is emerging across its vast plains: The loss of topsoil that much of the nation's food supply relies on.

The global burden of pathogens and pests on food crops

Crop pathogens and pests reduce the yield of agricultural production, causing substantial economic losses and reducing food security. Yet, their global burden and their variation over time and among different agroecosystems ...

Insect biological control shields tropical forests

Though often perceived as an environmentally-risky practice, biological control of invasive species can restore crop yields, ease land pressure and contribute to forest conservation. This paper illustrates the positive impacts ...
