Exposure to pyrethroids during child development linked to ADHD symptoms

Apr 20, 2015

A recent study in FASEB Journal used a number of different methods to determine if exposure to pyrethroid pesticides may result in symptoms similar to ADHD. Pregnant female laboratory mice were fed small levels of the pyrethroid pesticide deltamethrin to mimic the level of exposure that would be expected in humans. Once the babies of […]

Genetically engineered rice may make weeds stronger

Apr 16, 2015

A recent study published in the journal New Phytologist has demonstrated that genetically engineered crops may pass on extra benefits to nearby weeds. Scientists bred domesticated rice plants with wild weedy relatives of rice. They compared the growth rate and reproductive success of two types of rice hybrids. One hybrid type was created by breeding […]

More research shows that an organic diet can reduce exposure to some pesticides

Apr 14, 2015

Researchers from the University of California, Berkeley’s Center for Environmental Research and Children’s Health (CERCH), the University of Maryland’s Institute for Applied Environmental Health, and Emory University’s, Rollins School of Public Health recently published a paper showing that eating an organic diet reduces the exposure to some pesticides in young children.  The study looked at […]

Dietary exposure to pesticides associated with reduced semen quality

Mar 31, 2015

A new study out of Harvard University has linked dietary exposure to pesticides with lower sperm quantity and quality in men. Three hundred thirty-eight semen samples were collected from 155 men from 2007 – 2012. The diet of each participant was assessed using a dietary survey. The concentration of sperm and level of movement were […]

Herbicides, including glyphosate, increase antibiotic resistance in E. coli and Salmonella

Mar 25, 2015

A new study in mBio, a peer-reviewed journal published by the American Society for Microbiology, suggests that the herbicides dicamba (Kamba), 2,4-dichlorophenoxyacetic acid (2,4-D) and glyphosate (Roundup) induce antibiotic resistance in E. coli and Salmonella bacteria. Researchers subjected bacteria to combinations of different herbicides and antibiotics, including antibiotics commonly used to treat bacterial infections in […]

Organic management in apple orchards increases beneficial fungal diversity in soils

Mar 25, 2015

Arbuscular mycorrhizal fungi (AMF) live in cooperative relationship with many plants. Living in the soil with plant roots, they obtain sugars from the plant and, in return, bring minerals and nutrients from the soil to the plant’s roots and protect the plant from root pathogens and predators found in the soil. Because of the great […]

Exposure to glyphosate “probably causes cancer in humans”

Mar 23, 2015

A new study published by the World Health Organization (WHO) has determined that exposure to glyphosate, one of the primary pesticides used on genetically modified ‘round-up ready’ crops, “probably” causes cancer in humans. Glyphosate is one of the most commonly used herbicides in the world and is found in over 750 different products used on […]

Density of pest insects determines harm from neonicotinoids to beneficial predators

Mar 20, 2015

Neonicotinoid pesticides have been criticized for the harm they may cause to non-herbivore insects such as bees. Now, a growing body of literature suggests that their use may also indirectly harm beneficial insects that prey on insect pests. One recent study published in the scientific journal Crop Protection found that when wheat was treated with […]

Effect of chronic field-realistic exposure to the neonicotinoid, Imidacloprid, on honeybee colony health

Mar 19, 2015

A new study published by PLOS One shows that the neonicotinoid pesticide, imidacloprid, can have subtle negative effects on bee health. The study, conducted by Researchers from the University of Maryland and USDA-ARS conducted a three-year study to determine how imidacloprid levels within hives changed over time and how chronic low-level exposure to the neonicotinoid, imidacloprid […]

Microbial communities in organic soils suppress pathogens

Mar 17, 2015

Organic soils support much higher levels of biodiversity than conventional soils. It has been hypothesized that this abundance of ‘good’ soil organisms works to suppress soil pathogens such as fungi or bacteria that attack plant roots. A recent study published in the journal Applied Soil Ecology tested to see whether the soil pathogen flax wilt […]
