Sugarcane Aphid at Treatment Threshold in Southern High Plains Counties

At a minimum, Floyd, Crosby and Lubbock counties now have sorghum fields at the economic threshold of 50 to 125 sugarcane aphids per leaf and insecticide applications started over the weekend. Blayne Reed, Extension Agent - IPM in Hale, Swisher and Floyd counties said that private consultants called in the first Floyd County applications today. Monti Vandiver, Syngenta Crop Protection and former Extension Agent - IPM, said that the aphids in Crosby and Lubbock counties are now at treatable levels. 

This is in no way meant to imply that the other infested counties don't have fields at threshold level, so it is imperative that all sorghum fields on the Southern High Plains be scouted. This aphid can go from barely noticeable to exceeding the economic threshold in as little as 5 days. All of the scouting procedures, treatment threshold and insecticide information is presented here: http://www.texasinsects.org/sorghum.html . 

This is a reprint of a news article I just posted on the Sugarcane Aphid News Site at http://txscan.blogspot.com . The SCA news website is the best place to stay current on Texas sugarcane information news and view the latest distribution maps.
