Oregon Bumblebee Kill Resolution


Bumblebee Pollinating a Flower

The case of the massive (50,000) bumblebee kill in Oregon has been settled. The court ruled that the bumblebees were killed by improper pesticide application. The pesticide, dinotefutan, was to blame. The Oregon Department of Agriculture (ODA) found that: 1) the linden trees were clearly in bloom; 2) Dinotefuran label states that the pesticide is known to be hazardous to bees when applied onto flowering trees in bloom; and 3) it was a violation of label instructions to use the pesticide under the circumstances.

The company responsible for the application was fined $555. and the two applicators each fined $555. Pesticide Label use instructions carry the force of law. Violations are subject to civil and criminal penalties. Users of pesticides should always read the label and follow the directions.

ODA has issued registration standards for 2014 more strict than federal (EPA) standards. Dinotefuran and imidacloprid products for use on plants must have an Oregon-specific label statement. The label will ban the application on basswood, linden, or Tilia species altogether. This is due to an interaction of tree allelochemicals with these insecticides.

ODA is emphasizing pollinator protection in applicator training sessions and in information for the general public. ODA has requested that the U.S. Environmental Protection Agency review Dinotefuran and other neonicotinoids to determine if additional label restrictions are necessary at the national level.

    Reblogged this on Science on the Land and commented:
    argylesock says… I told you about Oregon’s temporary ban on the neonic called dinotefutan after thousands of bees died http://argylesock.wordpress.com/2013/07/02/oregon-bans-some-insecticides-following-bee-deaths/ Now some very modest fines are being taken from the company who told its staff to spray the poison, and from those staff. {Sarcasm} Oh that’s all right then.
