A step forward in the fight of bees against mites

,
Canadian study provides new details on the interaction between bees in their post larval stage and the Varroa destructor, a mite capable of destroying up to 40 percent of pollinator colonies each year

“Further investigation is needed on nanopesticides,” Dutch researchers say

,
According to four scientists at Leiden University, current assessments of nanopesticides do not take into account some problems related to their use

What if invasive weeds were winning the war against glyphosate?

,
That's the hypothesis of an American study: in soils treated with glyphosate, plants targeted for eradication are spreading again. A phenomenon that dampens the enthusiasm that has partly surrounded the controversial herbicide since its launch

Nanoparticles are a sustainable weapon against soil pests

,
According to the University of California, the use of plant-derived nanoparticles can reduce the amount of pesticides used and the chances of soil contamination

Pesticides persist in bee pollen, study says

,
An Irish study shows that pollen from several bee species retains traces of toxic substances from neonicotinoids. And researchers are concerned
Present in several products, including fire extinguisher foam, fluoride-based pollutants, so-called PFAS or per- and polyfluoroalkyl substances, are extremely difficult to dispose of. Photo: Brett Clashman, U.S. Air Force Public domainPhoto: Brett Clashman, U.S. Air Force Public domain

Ball milling cleans soil of persistent fluoride

,
Researchers in New Zealand are testing a solution against fluoride pollution. The technique has made it possible to degrade per- and polyfluoroalkyl substances (PFAS) at the molecular level with 99.9 percent efficacy

Pesticides do not escape nanosensors. From Sweden a low-cost solution

,
Inexpensive nanosensors can detect pesticides in orange juice, explain researchers at Karolinska Institutet in Stockholm. Experimentation has shown their efficacy and the possibility of massive production
Per- and polyfluoroalkyl substances are typically found in fluorinated pesticides that contain one or more fluorine atoms in their molecular structure and are considered particularly effective in combating plant pests.

Worrying data in the U.S. on PFAS contamination in soil

,
In New Hampshire, the presence of fluorine-based substances was detected in all soil samples taken by researchers. These products, known as PFASs and contained in pesticides, are typically difficult to dispose of
For years the number of insects has been steadily, worryingly decreasing. PHOTO: Pixabay

Insects in decline? “it’s a fault of soil consumption and pollution”

,
A Swiss-German study investigated the main factors behind the constant decline of insects and their biodiversity. Invasive species and intensive agriculture are also of concern. 40% of all species will be at risk of extinction in the coming decades.
From 2009 to 2020, sales of pesticides in Germany decreased only slightly, from about 30,000 to 28,000 tons per year. Photo: Jakob Huber/Campact Attribution-NonCommercial 2.0 Generic (CC BY-NC 2.0)Jakob Huber/Campact Attribution-NonCommercial 2.0 Generic (CC BY-NC 2.0)

Germany, the reduction in the use of pesticides is still too slow

,
The use of pesticides in Germany decreased by less than 10 percent between 2009 and 2020. The figure raises many concerns about the spread of integrated pest management, a technique designed to reduce the use of the most dangerous chemicals
