Grain Sorghum IPM 5/30/25

Posted on by

Grain sorghum fields range from bloom to soft dough. We are still finding stink bugs in sorghum fields, average fields have 1 stink bug per head but some are higher.Treatment thresholds are low at bloom and increase as the grain matures.  Some of the fields have leaf footed bugs. These insects can be considered as stink bugs since they feed in a similar manner. Sugarcane aphid numbers were low this week.  Continue to monitor for aphids when scouting for stink bugs and headworms. More Grain Sorghum pest management… Read More →

Grain Sorghum IPM Update 5/25/25

Posted on by

Sorghum field maturity ranges from pre-boot to post bloom milk stage. Much of the area has blooming sorghum fields. While the field blooms scout for midge every morning between 8:30 and noon.  After noon, the adult midge have completed their life cycle and die.  Use the table below to determine your economic threshold for managing midge. We began to find rice stink bugs in sorghum fields this week from Refugio to Victoria. Rice stink bugs can be very damaging to sorghum at bloom and their damage lessens at… Read More →

IPM Update – Stink Bugs in Grain Sorghum

Posted on by

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 →

Midge in Grain Sorghum

Posted on by

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 →

Stink Bugs in Grain Sorghum

Posted on by

The Stink Bug is a primary insect pest of grain sorghum from bloom until hard dough. The insect feeds directly on the seed, reducing seed weight and yield. The most common stink bug in grain sorghum of the Mid-Coast is the Rice Stink Bug. Scout sorghum after bloom using a small bucket and beat heads into the bucket and see what is being captured in the bucket. Look here for a brief video. Economic thresholds (ET) have been evaluated and can be determined using tables or equations, but this… Read More →
