The thousands of showgoers that attended Ag Progress Days in Rock Springs, Pennsylvania, from Aug. 16-18 could breathe a little easier thanks to the state’s soybean growers. That's because the Ag Progress Days staff, working with the Pennsylvania Soybean Board, controlled the dust from the show’s gravel roads through a soy-based dust control agent known as DustKill.

DustKill, a soy-based product applied by DustKill East of Paradise, Pennsylvania, is a safe, biodegradable alternative to chemical and petroleum-based dust suppressants. The product penetrates dirt road surfaces, binding loose gravel to dust and creating a compacted surface similar in texture to asphalt. Because soybean oil is not water soluble like some traditional dust suppressants, it’s a non-toxic, environmentally friendly product that lasts longer and doesn’t run off into ground water. A full-rate DustKill application, which lasts about a year, effectively holds down dust, improving air quality and reducing sediment and airborne erosion from roads into streams and waterways. PD
