A Syracuse University professor has demonstrated that ammonium -- an odiferous chemical compound, often used in fertilizer -- was a vital source of nitrogen for early life on Earth.
In the fall of 2017, leaves of phasey bean plants in Homestead, Florida, displayed powdery fungal growth, which appeared in the form of white spots on both sides of the leaves. Scientists conducted analysis by sequencing genes of genomic DNA and identified the fungus as Erysiphe fallax, which causes a disease known as powdery mildew. To their knowledge, this is the first report of powdery mildew on phasey bean in the United States.
When thinking about ways to end global hunger, many scholars focus too narrowly on increasing crop yields while overlooking other critical aspects of the food system.
Imagine a technology that could target pesticides to treat specific spots deep within the soil, making them more effective at controlling infestations while limiting their toxicity to the environment. Researchers at the University of California San Diego and Case Western Reserve University have taken a step toward that goal. They discovered that a particular plant virus can deliver pesticide molecules deeper below the ground, targeting places normally beyond their reach.
The study shows the advantages of herbicide spraying and intensive fertilization in reforestation programs to mitigate the effects of climate change.
Harmful algal blooms pose a unique toxic threat in Lake Erie's central basin, new research has found. Not only do blooms routinely occur in this area, which previously was not thought to be an area of concern, they can also produce types of cyanobacterial toxins that aren't typically detected through routine water-safety monitoring, according to a study published in the Journal of Great Lakes Research.
New analysis by the UK Trade Policy Observatory is warning of a significant weakening of enforcement arrangements covering the approval of pesticides as part of legislative changes carried out under the EU Withdrawal Act.
Kochia is a highly invasive weed that is common in the Great Plains, where it has developed resistance to multiple herbicides. Now new dicamba-resistant strains are adding to grower worries.
Scientists recycle phosphorus by combining dairy and water treatment leftovers.
In nature conservation and agriculture, there are two opposing views of how to combine high biodiversity and sustainable food production: nature conservation should either be integrated into agricultural land, or segregated into protected areas in order to enable maximum yields in the food production areas. Researchers at the University of Göttingen advocate coordinated approaches that combine nature conservation and agricultural production in sustainably managed landscapes. The results have been published in the journal People and Nature.
