Researchers have revived 80-year-old fungal pathogens from a museum collection and found that these pre-Green Revolution strains differ significantly from modern ones, revealing how decades of pesticide use and intensive farming have reshaped plant pathogens. By comparing the old and new fungi, the team uncovered critical insights into the evolution of fungicide resistance, environmental adaptation, and plant disease dynamics, paving the way for more sustainable, informed strategies in modern agriculture.
Acidic soils pose a major threat to crop yields due to toxic aluminum ions, especially in sensitive plants like tomato.
New Arizona State University-led research findings from studying over two decades of satellite observations reveal that the Earth’s continents have experienced unprecedented freshwater loss since 2002, driven by climate change, unsustainable groundwater use and extreme droughts. The study highlights the emergence of four continental-scale “mega-drying” regions, all located in the northern hemisphere, and warns of severe consequences for water security, agriculture, sea level rise, and global stability. The research team reports that drying areas on land are expanding at a rate roughly twice the size of California every year. And, the rate at which dry areas are getting drier now outpaces the rate at which wet areas are getting wetter, reversing long-standing hydrological patterns. The negative implications of this for available freshwater are staggering. 75% of the world’s population lives in 101 countries that have been losing freshwater for the past 22 years.
