Bayer Under Threat With Syngenta by U.K. Insecticide Reviews

Bayer AG and Syngenta AG face more pressure over crop chemicals suspected in bee-deaths as retailers including J Sainsbury Plc, the U.K.’s third largest supermarket chain, said they’re looking into the matter.

“At present we have not banned the use of neonicotinoids in plant protection products but we are monitoring the situation very closely,” a Sainsbury spokesman said by e-mail. Retailer Marks & Spencer Group Plc is reviewing its position on the pesticides and will announce an update in about a month, a spokesperson said. Tesco Plc, the U.K.’s biggest grocer, said it will be guided by government advice.
