National Slow the Spread Program.
The National Slow the Spread (STS) Program is dedicated to slowing the spread of spongy moth (Lymantria dispar) throughout the U.S. The STS Program is part of the USDA's integrated pest management (IPM) program and national strategy for Lymantria dispar management. Slow the Spread efforts are coordinated by a chartered, non-profit foundation that coordinates the operations of the program and facilitates the movement of funding between federal (USDA Forest Service and APHIS) and state agencies. Slow the Spread is one of the world’s largest and most successful integrated pest management programs.
