While there are many pests affecting cotton, the reniform nematode is one the most damaging, with the ability to cause annual losses of approximately $33 million within the Mid-Southern United States. Farmers struggle to manage this pest as commercially available resistance is not widespread and a limited number of products are commercially available for use in suppressing the reniform nematode.
To judge the overall effectiveness of cover crops and choose those offering the most ecosystem services, agricultural scientists must consider the plants' roots as well as above-ground biomass, according to Penn State researchers who tested the characteristics of cover crop roots in three monocultures and one mixture.
Flavonoid compounds -- produced by the roots of some sorghum plants -- positively affect soil microorganisms, according to Penn State researchers, who suggest the discovery is an early step in developing a frost-resistant line of the valuable crop for North American farmers.
Researchers have shed fresh light on the evolution and function of the shapes we see in nature - using as a model the heart shaped fruits of the Capsella genus.
Researchers show that 'Madsen,' a commonly used wheat variety, is resistant to more pests and diseases than recently thought, making it a good source of genes for breeding better wheat.
It took two years and $11 million, but eventually ranchers, politicians and scientists came to a consensus about how to prevent flooding in Tillamook, a coastal Oregon town. A recent study by Portland State University researchers examined the social factors involved in this decision-making process. This study showcases how environmental justice can be served when affected parties have a seat at the table.
When survival over generations is the end game, researchers say it makes sense to undervalue long shots that could be profitable and overestimate the likelihood of rare bad outcomes.
In recent years, the number of people affected by coeliac disease, wheat allergy or gluten or wheat sensitivity has risen sharply. But why is this the case? Could it be that modern wheat varieties contain more immunoreactive protein than in the past? Results from a study by the Leibniz-Institute for Food Systems Biology at the Technical University of Munich and the Leibniz Institute of Plant Genetics and Crop Plant Research are helping to answer this question.
Intensified rainstorms predicted for many parts of the United States as a result of warming climate may have a modest silver lining: they could more efficiently water some major crops, and this would at least partially offset the far larger projected yield declines caused by the rising heat itself.
Scientists are closer to gaining the upper hand on Huanglongbing, a disease that has wiped out citrus orchards across the globe. New models of the bacterium linked to the disease reveal control methods that were previously unavailable.
