Green Deal: Good for a climate-neutral Europe - bad for the planet
Europe is to become the first climate-neutral continent- this goal of the 'Green Deal' was announced by the EU in late 2019. Carbon emissions shall be reduced, while forestation, agriculture, environmentally friendly transport, and renewable energies shall be pushed. In Nature, scientists of Karlsruhe Institute of Technology (KIT) show that this ''Green Deal'' might be a bad deal for the planet, as the EU will outsource environmental damage by high imports of agricultural products.

NIST researchers advance efforts to accurately measure glyphosate pesticide in oats
For a commonly used pesticide known as glyphosate, concerns exist over how high a level is safe in food as well as the safety of one of its byproducts, known as AMPA. Researchers at the National Institute of Standards and Technology (NIST) are advancing efforts to measure glyphosate and AMPA accurately in the oat-based food products where they frequently appear by developing reference materials.

Pesticides and food scarcity dramatically reduce wild bee population
The loss of flowering plants and the widespread use of pesticides could be a double punch to wild bee populations. In a new study, researchers at the University of California, Davis, found that the combined threats reduced blue orchard bee reproduction by 57 percent and resulted in fewer female offspring.

Can organic plant protection products damage crops?
Protecting crops against pests and diseases is essential to ensure a secure food supply. Around 95 percent of food comes from conventional agriculture, which uses chemical pesticides to keep crops healthy. Increasingly, organic pesticides are sought as an alternative. Some organic pesticides contain live spores of the fungus Trichoderma to suppress other pathogens. Researchers at Göttingen University found one Trichoderma species can cause severe rot in cobs of maize (corn). Results were published in Frontiers in Agronomy. (2020-09-30)

Dozens of pesticides linked with mammary gland tumors in animal studies
In an analysis of how regulators review pesticides for their potential to cause cancer, researchers at Silent Spring Institute identified more than two dozen registered pesticides that were linked with mammary gland tumors in animal studies. The new findings raise concerns about how the US Environmental Protection Agency (EPA) approves pesticides for use and the role of certain pesticides in the development of breast cancer. (2020-08-04)

Pesticides can protect crops from hydrophobic pollutants
Researchers have revealed that commercial pesticides can be applied to crops in the Cucurbitaceae family to decrease their accumulation of hydrophobic pollutants, thereby improving crop safety. The team developed two approaches to control the functions of plant proteins related to the transport of hydrophobic pollutants. These findings will lead to these new functions of pesticides being utilized in agriculture, enabling safer crops to be produced. (2020-07-27)

What silicone wristbands say about chemical exposure in Uruguayan children
Researchers used silicone wristbands to examine the extent of chemical exposure among a small group of children in Montevideo, Uruguay. The 6- to 8-year-olds wore the bands for seven days. After analyzing the wristbands, researchers found an average of 13 pollutants in each one collected. Some of the wristbands showed exposure to DDT, a harmful pesticide that has been banned for use in many countries, including the U.S., since the 1970s. (2020-07-20)

Pesticides speed the spread of deadly waterborne pathogens
Widespread use of pesticides can speed the transmission of the debilitating disease schistosomiasis, while also upsetting the ecological balances in aquatic environments that prevent infections, finds a new study led by researchers at the University of California, Berkeley. The infection, which can trigger lifelong liver and kidney damage, affects hundreds of millions of people every year and is second only to malaria among parasitic diseases, in terms of its global impact on human health.

Study calls for reallocation of subsidies for biocontrols to fight fall armyworm
A new CABI-led study is calling for governments to reallocate subsidies to encourage the use of lower risk control options - such as biopesticides - in the fight against the devastating maize pest fall armyworm. The research suggests that the enforcement of pesticide regulations is also needed to curb the use of highly toxic and banned products such as monocrotophos, dichlorvos and methamidophos (2020-06-17)

An essential sustainable farming practice faces one big limitation: Land to produce seeds
The growth in cover cropping in the United States may soon hit a ceiling: planting millions of acres of cover crops requires huge extensions of land to produce cover crop seed. Between 3 and 6 percent of the 92 million acres of cropping land currently used for corn (maize) in the U.S. may be required to produce cover crop seed for that land area. (2020-06-11)

Milkweed, only food source for monarch caterpillars, ubiquitously contaminated
New evidence identifies 64 pesticide residues in milkweed, the main food for monarch butterflies in the west. Milkweed samples from all of the locations studied in California's Central Valley were contaminated with pesticides, sometimes at levels harmful to monarchs and other insects. 32% of the samples contained pesticide levels known to be lethal to monarchs, according to a study released today in Frontiers in Ecology and Evolution. (2020-06-08)

DDT, other banned pesticides found in Detroit-area black women: BU study
A new Boston University School of Public Health (BUSPH) study published in the journal Environmental Research finds detectable levels of DDE (what DDT becomes when metabolized in the body) and other banned organochlorine pesticides (OCPs) in the blood of over 60 percent of a cohort of black women of reproductive age in the Detroit area, with higher levels in women who smoked cigarettes daily, drank more alcohol, and drank more water. (2020-05-06)

'We urgently need a renewed public debate about new breeding technologies'
Plant breeding has considerably increased agricultural yields in recent decades and made a major contribution to combating global hunger and poverty. At the same time, however, the intensification of farming has had negative environmental effects. A recent study by the University of Göttingen shows that new plant breeding technologies - such as genetic engineering and gene editing - can help increase food production whilst being more environmentally friendly. Results were published in Applied Economic Perspectives and Policy. (2020-04-27)

How much does it cost california cannabis growers to safety test?
The high cost of testing cannabis in California leads to higher prices for the consumer, which could drive consumers to unlicensed markets. A new study from researchers at the University of California, Davis, finds the safety tests cost growers about 10 percent of the average wholesale price of legal cannabis. The biggest share of this expense comes from failing the test. (2020-04-23)
