Aphids in Young Sorghum

Posted on by

  Young sorghum fields should be inspected for aphids. We typically see two kinds of aphids in young sorghum; the yellow sugarcane aphid and the corn leaf aphid.  This week, I have been finding corn leaf aphids in sorghum fields. Corn leaf aphids are oval and dark bluish-green and have black antennae, cornicles, and legs. There are winged and wingless forms. These aphids are usually found deep in the whorl of preboot sorghum, but they also occur on the underside of leaves, on stems, or in grain heads. … Read More →

Headworms in Grain Sorghum

Posted on by

Grain sorghum maturity ranges from milk to hard dough.  Sorghum fields that have not reached hard dough should be scouted for headworms and stink bugs.  And all sorghum should be scouted for sugarcane/sorghum aphids. We have not found aphids in colonies greater than 20-40 feet in size.  Most of these are being consumed by beneficial insects such as lady beetle, lacewing, and syrphid fly larvae. What was most noticeable this week was worms in younger sorghum fields.  The older sorghum in soft dough or beyond did not seem… Read More →

False Chinch Bugs in Grain Sorghum

Posted on by

Early last week, I received reports of false chinch bugs in sorghum fields around Corpus Christi. Several fields there were treated to prevent yield losses. Today, we found a field south of Victoria with alarming numbers of false chinch bugs in some of the sorghum heads. When you shake a sorghum head into the bucket and find 200+ bugs, it can be a bit concerning. After scouting around the field, I determined the field was averaging somewhere between  20 and 50 false chinch bugs per head.  It is… Read More →

Stink Bugs in Field Crops

Posted on by

The row crops in the Mid-Coast of Texas continues to progress at a normal rate. Cotton field maturity ranges from late squaring to the second week of bloom. Grain sorghum fields are from late bloom to near hard dough. And soybeans are blooming (R2), setting pods (R4) and filling pods (R5). In all of these crops, stink bugs are one of the primary insect pests of concern.  After bloom, cotton fields should be checked for stink bug management by opening 1-inch bolls and checking the inside for evidence… Read More →

Grain Sorghum Hybrid Trial Results

Posted on by

The results of the 2022 Calhoun and Victoria counties grain sorghum hybrid trials are as follows: Calhoun County Grain Sorghum Hybrid Trial Victoria County Grain Sorghum Hybrid Trial Soil Testing needs to be done prior to fertilizing for next year’s crop. Give me a call to discuss soil sampling to 24″ for residual nitrogen. We can do the sampling and send the samples to TAMU Soil Testing Lab. Stephen Biles 361-552-9747
