Helicopters are scheduled to take to the air above Shady Cove again today in a final session of spraying for gypsy moths.

Spraying is set between about 5:30 and 7:30 a.m. in areas generally south and east of the Rogue River and west of Highway 62.

The Oregon Department of Agriculture is spraying the biological pesticide bacillus thuringiensis, or Btk, over 336 acres. Foliage must be sprayed during the moth's feeding stage as a caterpillar, which lasts from when eggs begin hatching in late March until roughly the end of June.

Weather could change the schedule.
