Labels, restrictions proposed for neonicotinoid pesticides
SALEM — Neonicotinoid pesticides, which critics blame for death and illness among pollinators, would be subject to new restrictions and labeling rules under two bills proposed in Oregon.
Labels would be required for pesticides containing neonicotinoids, as well as seeds and raw crops treated with the chemicals, under Senate Bill 928.
The entire class of neonicotinoid insecticides would be restricted under Senate Bill 929 to only be available to licensed pesticide applicators, farmers and veterinarians.
These measures are necessary because neonicotinoids have been implicated in large-scale die-offs of pollinators, as well as long-term health problems for these species, according to proponents.
A March 27 hearing on the two bills before the Senate Environment and Natural Resources Committee attracted an overflow audience, including some supporters adorned with insect antenna headbands, wings and striped black-and-yellow outfits.
Proponents of the bill argued that studies have linked neonicotinoid pesticides to the decline of honey bees and other pollinators, adversely affecting their biological processes even when the exposure isn’t lethal.
“When exposed, an entire plant becomes toxic, including the pollen and nectar,” said Rep. Pam Marsh, D-Ashland, a sponsor of the bills.
It makes sense to limit neonicotinoid availability to farmers and others who are trained to use them judiciously, since many retail buyers don’t carefully read pesticide instructions and often assume more is better, she said.
“We have to take action and we have to do it now,” Marsh said.
Opponents of the bill argue the threat of neonicotinoids to pollinators is overstated, since they’re unlikely to come across the chemicals in the field at the same high concentrations they would in laboratory experiments.
Raw agricultural and horticultural commodities would be labeled under SB 928 as being treated with neonicotinoids even if they contain no residue of the chemicals, said Scott Dahlman, policy director of the Oregonians for Food and Shelter agribusiness group.
“They do break down over time,” he said.
An exemption in SB 929 allows farmers to use the insecticides but doesn’t explain who meets that description, Dahlman said. “There’s no such thing as a farmer card to prove you’re a farmer.”
Neonicotinoids do pose a risk to pollinators, but restricting their usage would likely have unintended effects, said Paul Jepson, director of Oregon State University’s Integrated Plant Protection Center.
Jepson said he’s neutral on the bill but asked lawmakers to consider the trade-offs of the legislation.
Without access to neonicotinoids, many backyard gardeners would probably substitute organophosphate and pyrethroid insecticides that also kill insects but are more toxic to humans, he said,
“I urge you to consider the consequences of using a blanket approach,” Jepson said.
