Ortho will change three products for roses, flowers, trees and shrubs by 2017 and other products later, said Tim Martin, vice president and general manager of Ortho, a division of Scotts Miracle-Gro Co. of Marysville, Ohio.

The chemicals, called neonics for short, attack the central nervous systems of insects. Some advocates say neonics are one of several reasons behind declining populations of bees, which are significant pollinators of food crops.

Oregon last year created a rule that bans the use of four types of bee-killing insecticides on linden trees and related species. The rule, enacted at the request of the Oregon Department of Agriculture, makes it illegal to spray lindens, basswood trees and their relatives with any product containing dinotefuran, imidacloprid, thiamethoxam or clothianidin. The four chemicals are all neonicotinoids.
