U.S. appeals court orders EPA to ban pesticide said to harm children

By GFM Network News, Jonathan Stempel August 9, 2018

New York | Reuters – A divided federal appeals court on Thursday ordered the U.S. Environmental Protection Agency to ban a widely-used pesticide that critics say can endanger children and farmers. The 2-1 decision by the 9th U.S. Circuit Court of Appeals in Seattle overturned former EPA administrator Scott Pruitt’s March 2017 denial of a petition by

Plants and unseen soil micro-organisms all need precious space to grow. And to gain that space, a microbe might produce and use chemicals that kill its plant competitors. But the microbe also needs immunity from its own poisons. By looking for that protective shield in micro-organisms, specifically the genes that can make it, a team

Imidacloprid, a neonic insecticide, has been targeted by Health Canada as an environmental threat to aquatic insects and pollinators.

Cereal, speciality crop and fruit and vegetable growers are gearing up for a final attempt to convince Health Canada that eliminating most agricultural uses of the neonic insecticide imidacloprid is an environmental step backward. The department said May 31 that an updated pollinator assessment by the Pesticide Management Regulatory Agency found that while the risks

By Manitoba Co-operator Staff December 4, 2017

Pyrethroid pesticides could be modified with a few molecular tweaks to eliminate pests while preserving beneficial insects like bees. Those are the findings of researchers at Michigan State University’s entomology department in a study featured in the current issue of Proceedings of the National Academy of Sciences. These pesticides target a protein known as the

U of S research reveals controversial insecticides are toxic to songbirds

By GFM Network News, University of Saskatchewan November 9, 2017

Saskatoon – Research at the University of Saskatchewan (U of S) has linked the use of insecticides to serious health issues in songbirds. “Studies on the risks of neonicotinoids have often focused on bees that have been experiencing population declines. However, it is not just bees that are being affected by these insecticides,” said Christy

New research may eventually see plants created that can shake off insect damage on their own.

A study by Swiss scientists has found trace levels of at least one neonicotinoid pesticide in three-quarters of the honey samples it collected from around the world. The study, spearheaded by a team from Switzerland’s Universite de Neuchatel and published in Friday’s edition of the journal Science, was meant to assess “global exposure of pollinators
