California Bans Pesticide Linked to Brain Damage in Children
A popular agricultural pesticide that has been linked to brain damage in children will no longer be sold in California starting in February, state officials announced on Wednesday, as the AP reported.
Under the agreement, farmers will still be allowed to use the pesticide chlorpyrifos, but will have to stop at the end of 2020.
If the manufacturer of chlorpyrifos had decided to embark on a protracted legal battle rather than voluntarily withdraw their product, the timeline for removing the pesticide would have been much longer, according to the Los Angeles Times.
"For years, environmental justice advocates have fought to get the harmful pesticide chlorpyrifos out of our communities," said Governor Gavin Newsom in a statement released by the California EPA. "Thanks to their tenacity and the work of countless others, this will now occur faster than originally envisioned. This is a big win for children, workers and public health in California."
The pesticide is widely used as farmers rely on it for some of the nation's most popular crops, including alfalfa, almonds, citrus, cotton, grapes and walnuts, according to the AP.
California environmental regulators have had a ban on chlorpyrifos in their sights for years. They had designated the pesticide "a toxic air contaminant" that is harmful when it enters the respiratory track or makes skin contact. That designation allowed yesterday's agreement to include a ban on aerial spraying of chlorpyrfios, as NPR reported.
The federal government also sought to stop the use of chlorpyrifos under the Obama administration. The Obama administration proposed banning the pesticide in 2015 when the federal Environmental Protection Agency (EPA) found that chlorpyrifos could pose harm to consumers. However, in early 2017, the EPA, under the Trump administration, reversed course and said there was too much uncertainty about it, as NPR reported.
Since the federal government walked back its plan to ban the pesticide, California moved to implement its own regulation. Hawaii and New York are already phasing in their own bans, according to the AP.
"The swift end to the sale of chlorpyrifos protects vulnerable communities by taking a harmful pesticide off the market," said California Secretary for Environmental Protection Jared Blumenfeld in a statement. "This agreement avoids a protracted legal process while providing a clear timeline for California farmers as we look toward developing alternative pest management practices."
The state did agree to kick in $5.6 million to help pesticide manufacturers develop a safer alternative.
"But just so you're aware, that's what agriculture does every day, we're always looking for new products, safer products that are effective," said Casey Creamer, president of the California Citrus Association, which represents about 5,000 growers, as the AP reported.
Creamer added that the he and his organization believe the risks are far less than what the state presented.
"We really thought the exposure assessments and risks were just inflated and it wasn't a true characterization of the protections that were already in place," he said according to the AP.
Corteva AgriScience, formerly known as Dow AgroSciences, is the largest manufacturer of the chemical. After mounting restrictions on applications of chlorpyrifos products over the last few years, the state chose to revoke product registrations this year, which is effectively a ban. Companies that make the pesticide, led by Dow, had asked for a hearing, which delayed implementation of the ban, according to the Los Angeles Times.
Corteva said in a statement that it reached the agreement "in the best interests of the affected growers," as the AP reported.
"Through recent actions, the state of California has improvised and implemented several uniquely challenging regulatory requirements for chlorpyrifos. These new, novel requirements have made it virtually impossible for growers to use this important tool in their state," Corteva said in its statement.
As for the federal government, EPA chief Andrew Wheeler had extended the safety review of chlorpyrifos until 2022, but complaints about its process have forced the agency to expedite the review process and to have a decision by next October, the Los Angeles Times reported.

Home gardening is having a boom year across the U.S. Whether they're growing their own food in response to pandemic shortages or just looking for a diversion, numerous aspiring gardeners have constructed their first raised beds, and seeds are flying off suppliers' shelves. Now that gardens are largely planted, much of the work for the next several months revolves around keeping them healthy.
Start With Prevention<p>Just as preventive steps like maintaining a balanced diet help keep humans healthy, home growers can take many actions to help their gardens thrive.</p><p>One key step is assessing soil fertility – the ability of soil to sustain plant growth – which can vary widely depending on your location and soil type. Low soil fertility limits food production and predisposes plants to disease and pests. University extension <a href="https://soiltesting.wvu.edu/" target="_blank">soil testing labs</a> can help evaluate the quality of garden soil and identify nutrient deficiencies and acidic soils, often at no charge.</p>

Diagnosing Problems<p>Common plant pathogens include <a href="https://www.apsnet.org/edcenter/disandpath/viral/introduction/Pages/PlantViruses.aspx" target="_blank">viruses</a>, <a href="https://www.apsnet.org/edcenter/disandpath/prokaryote/intro/Pages/Bacteria.aspx" target="_blank">bacteria</a>, <a href="https://www.apsnet.org/edcenter/disandpath/nematode/intro/Pages/IntroNematodes.aspx" target="_blank">nematodes</a>, <a href="https://www.apsnet.org/edcenter/disandpath/oomycete/introduction/Pages/IntroOomycetes.aspx#:%7E:text=The%20oomycetes%2C%20also%20known%20as,foliar%20blights%20and%20downy%20mildews." target="_blank">oomycetes</a> and <a href="https://www.apsnet.org/edcenter/disandpath/fungalasco/intro/Pages/IntroFungi.aspx" target="_blank">fungi</a>. All of these microorganisms, especially at an early stage of infection, are too small to see. But when they proliferate, they cause changes in plants that we can recognize.</p><p>Unlike insects, which move around on six legs or on wings through the air, pathogens can move unseen and unchecked from leaf to leaf on the wind, through the soil or in droplets of water. Some microbes have even formed intimate relationships with insects and use them as vehicles to move from plant to plant, which makes these pathogens even more challenging to manage. Unfortunately, by the time some pathogens make their presence known, the damage is already done.</p><p>We recently conducted a <a href="https://twitter.com/kasson_wvu/status/1265989041725624323" target="_blank">Twitter poll</a> of gardeners nationwide to find out which culprits plagued their gardens. People named <a href="https://ento.psu.edu/extension/factsheets/aphids" target="_blank">aphids</a>, <a href="https://ento.psu.edu/extension/factsheets/squash-vine-borer" target="_blank">squash vine borers</a>, <a href="https://ento.psu.edu/extension/factsheets/squash-bug" target="_blank">squash bugs</a> and <a href="https://ento.psu.edu/extension/factsheets/flea-beetle" target="_blank">flea beetles</a> as the most problematic insect pests. Their most troublesome pathogens included <a href="https://extension.wvu.edu/lawn-gardening-pests/plant-disease/fruit-vegetable-diseases/powdery-mildew" target="_blank">powdery mildew</a>, <a href="https://plantpath.ifas.ufl.edu/rsol/Trainingmodules/BWTomato_Module.html" target="_blank">tomato bacterial wilt</a> and <a href="https://extension.wvu.edu/lawn-gardening-pests/plant-disease/fruit-vegetable-diseases/downy-mildew" target="_blank">cucurbit downy mildew</a>.</p><p>To manage such perennial challenges, the first step is to spend time closely looking at your plants. Do you notice any insects consistently hanging around, or molds colonizing leaves or other plant parts? How about symptoms such as blight, stunting, or leaves that are yellowing, browning or wilting?</p>

As if the surging cases of coronavirus weren't enough for Floridians to handle, now the state's Department of Health (DOH) has confirmed that a person in the Tampa area tested positive for a rare brain-eating amoeba, according to CBS News. The Florida DOH posted a warning to residents to remind them of the dangers of the rare single-celled amoeba that attacks brain tissue.

The World Health Organization (WHO) is holding the line on its stance that the respiratory droplets of the coronavirus fall quickly to the floor and are not infectious. Now, a group of 239 scientists is challenging that assertion, arguing that the virus is lingering in the air of indoor environments, infecting people nearby, as The New York Times reported.
