IPM Update – Stink Bugs in Grain Sorghum

Grain Sorghum in the Mid Coast of Texas is blooming and some fields are just past bloom in the Milk stage.  Sorghum should be scouted every day or so during bloom to detect economic populations of sorghum midge.  During bloom, the primary insect pest is sorghum midge.  The economic threshold of sorghum midge is 1 midge per 3-5 plants. Another important insect pest of sorghum is stink bugs.  We have been finding stink bugs in sorghum fields but most are still below the treatment threshold. The most critical… Read More →

Sorghum Midge and Sugarcane Aphids

Grain sorghum across Refugio, Calhoun and Victoria Counties ranges from 4-5 leaf to bloom.  The two primary insects of concern this week for grain sorghum in the Mid-Coast of Texas are Sorghum Midge and Sugarcane Aphids. The Sugarcane Aphid can be found in Johnsongrass adjacent to sorghum fields, so the aphids may jump into the sorghum soon. Begin inspecting field margins and areas of the field with Johnsongrass present. Fields beginning to bloom should be inspected for Sorghum Midge. Begin scouting for midge soon after head emergence when… Read More →

Midge in Grain Sorghum

Grain sorghum fields range in maturity from nearing bloom to soft dough and all of these fields need to be scouted frequently. Blooming sorghum is susceptible to sorghum midge and field scouts are finding more midge in the fields this week. Scout sorghum fields 2-3 times per week until past bloom. Start by scouting fields on the south side (downwind) as the midge is a poor flyer and will be found on the field margins first. When you are finding them on field margins, move 150-200 feet into… Read More →
