[DNR] Porter County gypsy moth treatments delayed, likely to April 18
Start Date: 4/13/2012
End Date: 4/13/2012
Entry Description
Gypsy moth treatment for Porter County’s Cobbs Corner site, which was planned to start the week of April 16, may start on Wednesday, April 18.

Current weather forecasts indicate conditions are favorable for April 18, but the schedule could be delayed if weather conditions change. Forecasts predict weather will not be within the guidelines for treatment Monday or Tuesday, April 16-17.

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.

The Cobbs Corner site will receive two aerial treatments spaced four to 10 days apart, depending on weather and other factors. The site is the only area gypsy moth treatment planned for April or May. Mating-disruption gypsy moth treatment is planned for June.

Treatment updates will be posted at gypsymoth.IN.gov and on the Indiana gypsy moth Twitter site at http://twitter.com/#!/INdnrinvasive.

A map of the treatment site and further information may be found at gypsymoth.IN.gov.

During the April 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 (Bacillus thuringiensis var. kurstaki) Foray 76B, 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 flights will start at sunrise and continue as long as weather permits. With favorable weather, the treatment should be completed by late morning.

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.

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.
