The U.K. government is reversing a ban on a dangerous pesticide. The National Farmers’ Union (NFU) and British Sugar lobbied hard to get a product containing neonicotinoid thiamethoxam sanctioned for emergency use on sugar beets. Not only is this chemical thought to kill bees, but rainwater will wash it from fields into rivers. Last we heard, fish weren’t requesting neonicotinoid thiamethoxam any more than were insects, many of which already face serious declines.

Matt Shardlow, chief executive of the conservation group Buglife, was one of many environmentalists unhappy with the decision. “In addition, no action is proposed to prevent the pollution of rivers with insecticides applied to sugar beet,” Shardlow said. “Nothing has changed scientifically since the decision to ban neonics from use on sugar beet in 2018. They are still going to harm the environment.”

Beet yellows virus is carried by aphids and has a ruinous effect on sugar beet crops. The U.K. has tracked this disease with national surveys since 1946, charting the effects of chemicals, farm hygiene and other factors on the changes and developments in virus yellows disease. Treating sugar beet seeds with neonicotinoid thiamethoxam is one approach used to control this disease.

“Virus yellows disease is having an unprecedented impact on Britain’s sugar beet crop, with some growers experiencing yield losses of up to 80%, and this authorization is desperately needed to fight this disease,” said Michael Sly, chairman of the NFU sugar board. “It will be crucial in ensuring that Britain’s sugar beet growers continue to have viable farm businesses.” He emphasized that pesticides would be used in a limited and controlled way.

In 2018, the EU decided to protect bees by banning outdoor uses of thiamethoxam. But now 11 countries, including Spain, Denmark and Belgium, have signed emergency authorizations to use this controversial chemical.
