Spraying for Soybean Aphids and Mites
Special

Interest Points
Soybean aphid. Increasingly across Ohio, soybean aphids and soybean mites
are becoming a problem. Spray programs are necessary to keep these pests below economic levels. Common insecticides for controlling the soybean aphidare: Warrior (lambda-cyhalothrin), Asana (esfenvalerate), Lorsban (chlorpyrifos), • Registration -- our numbersare increasing Mustang (zeta-cypermethrin) and Furadan (Carbofuran). Under the rightconditions, all of these materials will kill bees.
Spray applications are on an “as needed” basis. Much of Ohio is already past theflowering stage, but some areas are still in flower and spraying is on-going.

John Grafton
It has been known that American Foulbrood was at some point going to beresistant to Terramycin (TM). In 2003 the first “moderately tolerant” sample results were returned from the USDA lab on a few samples from Ohio. In 2004 of the samples tested 54% were determined to be moderately tolerant. Thequestion remained as to when the first fully resistant sample would be found. The answer came on July 11, 2005 when a sample result came back with a 14MM zone of resistance. On the resistance chart anything 29MM or less is considered 8995 East Main StreetReynoldsburg, OH 43068 The sample was from a hobby beekeeper in northwest township of Williamscounty. The Ohio Dept. of Agriculture is currently working with this particular beekeeper, the USDA and the FDA to control this incident and to gain approval for e-mail: grafton_laptop @mail.agri.state.oh.us The disease, while posing no health risk to humans, is caused by a sporeforming bacteria known as Paenibacillus larvae. Only the spore stage isinfectious to honeybees. All castes of honeybees are susceptible to the disease; continued on page 3

Presently, I have not heard of any serious kills fromsoybean spraying, but beekeepers should be alertand protect their hives as much as possible.

Requeen every year. (Mr. Wilbanks requeens colonies. Diseased colonies left untreated will gradually die and subsequently the honey will be robbed out by other bees in the area, thus spreading Apistan® and ChekMite® strips and rotates the disease to those colonies. This may in timeaffect pollination and crop production in the area.
