[DNR] Gypsy moth treatments in Porter and Whitley counties to begin week of May 19
Start Date: 5/5/2014Start Time: 12:00 AM
End Date: 5/5/2014
Entry Description
Gypsy moth treatments for the infestation in Valparaiso (Porter County) and the Lorane site in Whitley County are planned to start the week of May 19. The actual day of treatment depends on weather and development of tree leaves.

The leaves need to be 50 percent expanded, approximately 2.5-3.0 inches long for oak trees, for the first application of the pesticide Btk, (Bacillus thuringiensis var. kurstaki Foray 76B).

The DNR will announce the actual day of treatment once determined. Each site will receive two aerial treatments of Btk spaced four to 10 days apart.
 
Treatment information is at gypsymoth.IN.gov and http://twitter.com/#!/INdnrinvasive.
 
During the treatment, people in and near the treatment area might notice a yellow crop duster airplane flying 50-125 feet above treetops as it releases Btk, a bacterium commonly found in the soil and frequently used in organic farming. Btk kills gypsy moth caterpillars as they feed on tree leaves by disrupting their digestive systems.

The flight will start at sunrise and will continue until completed by mid- to late morning, weather permitting.
 
Btk has been used for decades by organic gardeners and has an excellent safety record with people and animals. People who live or work near the treatment areas might choose to take common-sense precautions, including staying inside when the planes are flying and for about 30 minutes after treatments are complete. This gives the material time to settle out of the air and adhere to treetops.

In addition to following weather guidelines for treatment, DNR staff monitors leaf development. If leaf development slows because of weather, the treatment may be delayed for that reason and a press release will announce this change.
 
People with questions about this project can call the Indiana DNR toll-free at 1-866-NO EXOTIC (1-866-663-9684) or their Purdue County Extension office at 1-888-EXT-INFO (1-888-398-4636) during regular business hours.
