neonicotinoids

PAN has done a lot to spread the word about neonicotinoid pesticides and their adverse impacts on bees. But there are other repercussions for widespread use of neonics too, as an increasing number of studies highlight. Adverse impacts on wild pollinators, birds and other wildlife from neonics have also been in the news lately.

Neonics are the most widely used insecticides in the world, finding their way into ecosystems through water, soil and insects other species rely on for food. These chemicals were released onto the U.S. market without regulators fully understanding their impacts, and scientists continue to uncover more unintended consequences — from harming honey bees to song birds.

They’re in our garden plants, sprayed on orchards throughout the state, and used as seed coatings on commodity crops in California and across the country. After five years of review, California officials have not only failed to complete an evaluation of neonicotinoid pesticides (neonics), they continue to allow more and more of these bee-harming chemicals into the market.

Fed up with the years of hand-sitting, PAN and our partners brought the state and pesticide manufacturers to court today.

Bee-harming pesticides in our lavender and daisies? In the same week that an international body of scientists released a comprehensive global assessment of the harms of pesticides to bees, a new report shows that these very same pesticides are found in many of our backyard plants — at levels of concern — that are meant to support pollinators.

The report shows that 51% of garden plant samples purchased at top garden retailers (Home Depot, Lowe’s and Walmart) in 18 cities in the United States and Canada contain neonicotinoid (neonic) pesticides — a key driver of declining bee populations. Concerning levels of the pesticides were found in places like California’s San Francisco Bay Area and in Minnesota’s Twin Cities. In some cases, multiple neonics were found in the same plant, in the leaves, stalks or flowers.

Farmers have been saying it for years: it's nearly impossible to find corn seed that isn't pre-treated with neonicotinoid pesticides. At a Congressional briefing in DC last week, Dr. Christian Krupke of Purdue University presented hard data to support what farmers are reporting: 94% to 98% of corn seed in the U.S. is pre-treated with neonics. This is particularly bad news for pollinators, since we know neonics pose a threat to bees even at low levels.

Dr. Krupke and other scientists have been looking at this issue more closely, and recent studies are showing that neonic seed treatments don't actually add much value to crops. They don't improve yields and don't markedly reduce damage from common pests. The equation doesn't add up. If they harm bees AND don't add much benefit, why are these seed treatments so prevalent?

Pressure on the Environmental Protection Agency to safeguard bees continues to grow stronger. Today in DC, PAN joined partners to hand deliver a message from more than half a million people to EPA Administrator Gina McCarthy: Step up and prioritize protecting bees from harmful pesticides.

Even though independent studies clearly show that neonicotinoid pesticides (or "neonics") are hazardous to bees, EPA won't conclude its review of these chemicals until 2018. Meanwhile, neonics are the most widely used class of insecticides in the world. And bee populations continue to decrease at alarming rates.
