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.
"...as long as the Trump administration is in charge, this EPA will favor the interests of the chemical lobby over children's safety." In my 2nd @EcoWatch post today, #Trump's #EPA decided not to ban toxic #pesticide #chlorpyrifos: https://t.co/91WkwqaT0I

A herdsman in the Chinese autonomous region of Inner Mongolia was diagnosed with the bubonic plague Sunday, The New York Times reported.
<p>The Bayannur city health commission confirmed the diagnosis and issued a third-level alert, the second from the bottom in a four-level system. Mongolian health authorities are also investigating a second suspected case involving a 15 year old who developed a fever after coming into contact with a marmot that had been hunted by a dog, China's Global Times tweeted.</p>

<p>Bubonic plague is caused by the Yersinia pestis bacterium which is spread from infected rodents to humans by fleas, according to The New York Times.

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.
<p>Contrary to the <a href="https://biblehub.com/galatians/6-7.htm" target="_blank">Biblical adage</a>, we do not necessarily reap what we sow. As researchers specializing in <a href="https://www.davis.wvu.edu/faculty-staff/directory/matthew-kasson" target="_blank">plant</a> <a href="https://plantpath.psu.edu/directory/ctb14" target="_blank">pathology</a> and <a href="https://www.lovettbr.com/about" target="_blank">entomology</a>, we have devoted our careers to understanding and managing plant pests and pathogens. We are also gardeners with varying levels of experience and have seen firsthand the damage these insects and disease-causing agents can inflict.</p><p>Plant health is essential for seeing your garden succeed all the way to harvest. The United Nations General Assembly has declared 2020 as the <a href="https://www.apsnet.org/members/engagement/IYPH2020/Pages/default.aspx" target="_blank">International Year of Plant Health</a> to help bring needed attention to pests and diseases that threaten global food production.</p><p>Thousands of pests and pathogens are known to target commercial crops, but a few usual suspects are routinely responsible for havoc in gardens across the U.S. Although each organism's preferences vary, a few common tactics can help you detect them and protect your plants.</p>
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><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzQzNzU0Ni9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0NzE2MTA4MX0.TMP1j2YhGRmeSglNZ3bYQd-4ckRdv6WVB0yC0D48eus/img.jpg?width=980" id="e50c3" class="rm-shortcode" data-rm-shortcode-id="d73f4dd41b07cd5c3451a01298aabc76" data-rm-shortcode-name="rebelmouse-image" />
Using weed barrier landscape cloth for planting rows and mulching between rows is an effective way to suppress weeds. Matt Kasson, CC BY-ND
<p>Suppressing weeds, either through mulching or weeding by hand each week, increases air flow and reduces humidity around garden plants, making it harder for pests and pathogens to thrive. Weed control ensures that nutrients are available for the plants you want to grow.</p><p>Proper spacing between plants is also important. Crowding can contribute to disease and pest outbreaks, so check and follow recommendations on seed packs or online as you add and move plants throughout the season. You can always cull plants after they come up to help with spacing. In small gardens, fewer plants that are properly supported can produce a bigger harvest than many overcrowded plants.</p><p>And then there's the weather. Frost, hail, drought and flooding all pose unique risks to plants. Inconsistent rainfall can kill thirsty plants more quickly than infertile soils. Both too little and too much water will stress plants and can make them more vulnerable to severe pest and pathogen outbreaks.</p><p>A general rule of thumb is to follow a consistent daily watering regimen – preferably first thing in the morning – and to avoid over-watering, which can encourage root pathogens in soil.</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><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzQzNzU1MS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY1NzAzNjI3NX0.YMze8ypLJeMta1zj22z2Ol0gLeOaKPzuJUXAJDGMkWw/img.jpg?width=980" id="a7f6e" class="rm-shortcode" data-rm-shortcode-id="21b23fe729f14504c8177a38ae257301" data-rm-shortcode-name="rebelmouse-image" />

Naegleria fowleri (commonly referred to as the "brain-eating amoeba") is a free-living microscopic amoeba (single-celled living organism). Centers for Disease Control
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.
<p>The amoeba is known, scientifically, as <em>Naegleria fowleri</em>. Only four people have survived <em>Naegleria fowleri</em> in the U.S. between 1962 and 2016, out of 143 who contracted the disease, as <a href="https://www.independent.co.uk/news/world/americas/florida-brain-eating-amoeba-warning-naegleria-fowleri-a9603026.html" target="_blank">The Independent</a> reported. There have been only 37 cases reported in Florida since 1962, which makes up nearly 26 percent of all instances in the U.S.</p><p><em>Naegleria fowleri</em> is typically found in warm freshwater such as lakes, rivers and ponds. The Florida DOH has cautioned people who swim in those freshwater sources to be aware of the amoeba's possible presence, particularly when the water is warm, according to CNN.</p><p>The DOH did not disclose where in Hillsborough County the patient had contracted the amoeba, nor the patient's condition, according to The Independent.</p>
<p>The amoeba's deadly effects happen when it causes a rare infection of the brain called primary amebic meningoencephalitis (PAM), which destroys brain tissue and is usually fatal, according to <a href="https://www.foxnews.com/health/brain-eating-amoeba-infection-florida-rare-hillsborough-county-health" target="_blank">Fox News</a>.</p><p>"Infections can happen when contaminated water enters the body through the nose," the DOH said in its letter.</p><p>After the amoeba enters the nose through contaminated water, it then travels to the brain where it causes PAM, according to health officials.</p>
<p>"Infections usually occur when temperatures increase for prolonged periods of time, which results in higher water temperatures and lower water levels," health officials stated in their letter.</p><p>Health officials recommend using a nose plug, pinching your nose or keeping your head above water to avoid the amoeba. They also recommend avoiding water where conditions are ripe for the amoeba to thrive, such as warm freshwater around power plants and shallow fresh water during periods of high water temperature.</p><p>"Adverse health effects on humans can be prevented by avoiding nasal contact with the waters, since the amoeba enters through nasal passages," the DOH said, as CNN reported.</p>
<p>As CNN pointed out, the ancient tradition of treating congested sinuses with a neti pot can also increase the risk of infection.</p><p>"Use only boiled and cooled, distilled, or sterile water for making sinus rinse solutions for neti pots or performing ritual ablutions," the DOH said.</p><p>It is also possible to contract the amoeba in swimming pools that are not properly chlorinated. Since it's only contracted through the nose, there is no chance of developing PAM from drinking it, according to CBS News.</p><p>As CBS News noted, the typical symptoms of a <em>Naegleria fowleri</em> infection include severe frontal headache, fever, nausea and vomiting. Later symptoms include stiff neck, seizures, altered mental status, hallucinations and coma.</p>
<p>Signs of infection typically start a few days after swimming or other nasal exposure to contaminated water. People usually die within 1 to 18 days after symptoms begin.</p><p>"It is essential to seek medical attention right away, as the disease progresses rapidly after the start of symptoms," the health department said.</p><p>The DOH added that "this disease is rare and effective prevention strategies can allow for a safe and relaxing summer swim season," as The Independent reported.</p>

Airborne Coronavirus Transmission Must Be Taken Seriously, 239 Scientists Tell WHO

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.
<p>The idea that the virus lingers in the air may explain why the virus is finding new victims to infect in clusters as people visit bars, restaurants, gyms and casinos worldwide.</p><p>In an open letter to the WHO, 239 scientists from 32 countries outlined the evidence that proves smaller particles can infect people, and are calling for the agency to revise its recommendations. The researchers plan to publish their letter, titled "It is Time to Address Airborne Transmission of COVID-19," in a scientific journal this week, according to The New York Times. The paper will be published in <em>Clinical Infectious Diseases</em>, according to <a href="https://www.washingtonpost.com/world/europe/coronavirus-airborne-spread-world-health-organization/2020/07/05/9de19c38-bed8-11ea-b4f6-cb39cd8940fb_story.html" target="_blank">The Washington Post</a>.</p>
<p>"We are aware of the article and are reviewing its contents with our technical experts," WHO spokesman Tarik Jasarevic said in an email reply to a <a href="https://www.reuters.com/article/us-health-coronavirus-airborne/hundreds-of-scientists-say-coronavirus-is-airborne-ask-who-to-revise-recommendations-nyt-idUSKBN2460O7" target="_blank">Reuters</a> request for comment.</p><p>However, as recently as last Monday, the WHO <a href="https://www.who.int/publications/i/item/WHO-2019-nCoV-IPC-2020.4" target="_blank">published guidelines</a> on stopping the spread of the virus in healthcare facilities that said airborne transmission of the virus is possible only after medical procedures that produce aerosols, or droplets smaller than 5 microns, or 5 millionths of a meter.</p><p>The fact that scientists resorted to a paper to pressure the WHO is unusual, analysts said to The Washington Post. It is likely to renew questions about the WHO's messaging.</p>
<p>"WHO's credibility is being undermined through a steady drip-drip of confusing messages, including asymptomatic spread, the use of masks, and now airborne transmission," said Lawrence Gostin, a professor of global health law at Georgetown University who provides technical assistance to the WHO.</p><p>Gostin did compliment the WHO for hosting regular briefings, noting that the organization is in a tricky situation because it "has to make recommendations for the entire world and it feels it needs irrefutable scientific proof before coming to a conclusion."</p><p>And yet, he sees the writing on the wall that "the public, and even scientists, will lose full confidence in WHO without clearer technical guidance," as The Washington Post reported.</p>
<p>The signatories of the letter do not think their letter should raise panic. Instead, it should make the WHO revisit their guidance to focus more on respiratory aspects of the virus and less on hand sanitizer and hygiene.</p><p>"There is no reason for fear. It is not like the virus has changed. We think it has been transmitted this way all along," said Jose Jimenez, a chemist at the University of Colorado who signed the paper, as The Washington Post reported. "Knowing about it helps target the measures to control the pandemic more accurately."</p><p>Jimenez added that the scientists' purpose in writing the letter was not to hurt the WHO, but merely to encourage it to consider new information.</p><p>"Our group of scientists doesn't want to do anything that would undermine the WHO as an organization," he said. "We only want it to adapt its guidance on aerosol transmission to the increasing evidence."</p>

<p>LaDon Swann of the Mississippi-Alabama Sea Grant Consortium says the shellfish require water that's salty, but not too salty.</p><p>"So it's kind of like Goldilocks. … You know, an oyster's really looking for that perfect location," he says. "When they find that water that's just right, that's where they make their home."</p><p>But climate change is throwing off that balance. When heavy rain falls, too much freshwater may flow from the Mississippi River into the oyster reefs.</p>
<p>"Oysters can survive that for a short period of time, but if it goes beyond just a few days, then it affects their health, and ultimately you see mass mortalities of oysters because of the freshwater inflow," Swann says.</p><p>On the other hand, when there's not enough rain, the water around oyster beds gets too salty. That allows saltwater predators – such as a snail called the oyster drill – to enter oyster habitat.</p><p>This snail can make a hole in the oyster's shell, suck it out, and digest it.</p><p>So Swann says as climate change causes precipitation extremes at both ends of the spectrum, wild Gulf Coast oysters may lose the "just right" Goldilocks zone they need to thrive.</p>
