A combined treatment of irradiation and essential oil vapors could effectively destroy insects, bacteria and mold in stored grains. The team of INRS Professor Monique Lacroix has demonstrated the effect of this process on insects affecting rice. The study was published in the Radiation Physics and Chemistry journal.
New research reveals an essential step in scientists' quest to create targeted, RNA-based, more eco-friendly fungicides that protect food crops.
Pervoskite nanocrystals, a key component of emerging solar energy technology, are being used in Australia to develop a new, rapid-response detection mechanism for fumigants, pollutants and nerve agents. The technology, developed by the ARC Centre of Excellence for Exciton Science, Australia's national science agency CSIRO and the Department of Defence, could be used to protect emergency services, defence personnel and agricultural workers.
Although the use of pesticides in agriculture is increasing, some farms have transitioned to organic practices and avoid applying them. But it's uncertain whether chemicals applied to land decades ago can continue to influence the soil's health after switching to organic management. Now, researchers reporting in ACS' Environmental Science & Technology have identified pesticide residues at 100 Swiss farms, including all the organic fields studied, with beneficial soil microbes' abundance negatively impacted by their occurrence.
Researchers uncovers natural disease resistance in chickpeas as a harmful pathogen develops resistance to fungicide.
Pesticides used in forestry may threaten species in downstream rivers and estuaries, but little is known about the extent to which this occurs. A new study by researchers at Portland State University found mussels, clams and oysters in watersheds along the Oregon Coast are exposed to pesticides used in managing forests. The results of this study, published in the journal Toxics, have implications for developing better forest management practices that are less likely to negatively affect aquatic life.
A recent article in the journal Weed Science explores whether harvest-time controls would be effective against downy brome, Italian ryegrass, feral rye and rattail fescue - weeds that compete with winter wheat in the Pacific Northwest.
The agricultural cultivation of the staple food of rice harbours the risk of possible contamination with arsenic that can reach the grains following uptake by the roots. A Chinese-German research team of Heidelberg University and Nanjing Agricultural University studied over 4,000 rice variants and discovered a plant that resists the toxin as well as contains a large amount of the trace element selenium.
An insecticide used to control pest infestations on squash and pumpkins significantly hinders the reproduction of ground-nesting bees -- valuable pollinators for many food crops, new research has revealed.
A widespread field search for a rare Australian native bee not recorded for almost a century has found it's been there all along - but is probably under increasing pressure to survive. "This is concerning because it is the only Australian species in the Pharohylaeus genus and nothing was known of its biology," Flinders University researcher James Dorey says in a new scientific paper in the journal Journal of Hymenoptera Research.
