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 →

Grain Sorghum Across the Board

Sorghum fields range in maturity from 4-5 leaf to bloom. This is the result of planting across 5-6 weeks. As a result of this we need to be on the lookout for a wide variety of insect pests. Headed sorghum should be checked for stink bugs and headworms. Scout for these pests using a small bucket, beating the heads into the bucket and count what remains. Follow this link for a brief video demonstrating how to scout sorghum after bloom. LINK My economic threshold for headworms is 1… Read More →

Pest Management in Bloomimg Sorghum

Sorghum fields across the Mid-Coast of Texas are beginning to bloom. These fields are susceptible to sorghum midge damage. The sorghum midge is one of the most damaging insects of sorghum in Texas, especially in the southern half of the state.  The adult sorghum midge is a small, fragile-looking orange-red fly with a yellow head, brown antennae and legs and gray, membranous wings. During the single day of adult life, each female lays about 50 yellowish-white eggs in flowering spikelets of sorghum.  Eggs hatch in 2 to 3… Read More →
