Sorghum Headworms and Soybean Podworms

–by Dr. Jeff Whitworth, Dr. Holly Schwarting and J.R. Ewing

 

Most sorghum is at least flowering with much into milk, soft dough and even black layer.  Thus, headworm susceptible stages are mostly past as flowering to soft dough is the time frame for headworm vulnerability.  Once these advanced stages have been reached the head moth will start ovipositing in soybeans.  Soybeans then need to be continuously monitored, as long as there are new pods, for podworm damage and/or smaller podworms.
