EPA Approves Insecticides for Control of Stink Bug (June 2011)

EPA has approved dinotefuran and an additional insecticide for use against the invasive brown marmorated stink bug.

On June 24, 2011 EPA approved the insecticide dinotefuran for emergency use on tree fruit to help manage populations of the brown marmorated stink bug. The stink bug is an invasive insect that has caused widespread yield losses in tree fruit production in the mid- Atlantic region.

The approval of dinotefuran is known as an emergency exemption provision of the Federal Insecticide, Fungicide and Rodenticide Act, and it applies to Virginia, Maryland, Delaware, Pennsylvania, West Virginia, North Carolina and New Jersey. Under this exemption, producers of stone fruit (e.g. peaches, plums and cherries) and pome fruit (including apples and pears) are allowed to manage the stink bug using two applications of dinotefuran per season by ground equipment.

Under the emergency exception, states can petition EPA for the temporary use of an unregistered pesticide if it will help alleviate an emergency pest problem. However, prior to approval, EPA must be able to justify its use from a health and safety standpoint. EPA’s assessment of dinotefuran has found that the risks of exemption are within current safety standards. Dinotefuran has already been approved for use on leafy vegetables, cotton, grapes, potatoes and a variety of other crops.

On June 21, 2011, EPA approved an additional use for an insecticide that may help manage stink bugs in organic production systems. The new product is approved for use on many crops where stink bug management is needed and it can be used by organic farmers. The insecticide contains azadirachtin and pyrethrins, which are both derived from botanical ingredients

EPA is continuing to work with Congress, USDA, lead state agencies, universities, federal research agencies and private companies and growers, in an effort to develop sustainable management against the brown marmorated stink bugs.
