Sugarcane Aphids Above Threshold in Sorghum

Posted on by

While some sorghum fields in the Mid-Coast of Texas have already been harvested, the remaining fields should be inspected for Sugarcane Aphids (SCA). This week I have seen an increasing number of fields with treatable levels of aphids. Scout fields by walking at least 15-20 rows into the field and looking for honeydew on the plants. Two scouting methods can be followed depending on the threshold you plan on using. Once SCA are found in a field, use one of the following protocols to assess the need for… Read More →

Stink Bugs in Sorghum, Cotton and Soybeans

Posted on by

We have reached the time of the growing season when Stink Bugs are the primary pest in most of the row crops on the Texas coast. Sorghum maturity is from bloom to soft dough and will be susceptible to stink bugs until hard dough. Scout for stink bugs and headworms using a bucket to beat sorghum heads into until you have sampled 10.  Then stop and count the stink bugs and headworms in the bucket.  This should be done at 10-20 places per field and average the number of stink bugs… Read More →

Insects in the Field this Week – 5/12/07

Posted on by

There are a number of insects to be on the lookout for this week in the Grain Sorghum, Cotton and Soybeans of the Texas Coast. Grain Sorghum Grain sorghum fields vary widely with regard to crop maturity. The older fields are blooming and the youngest fields are 4-6 leaf. All sorghum fields should be monitored weekly for insect pests. The one insect that can cause problems season long is the Sugarcane Aphid. I have found them in low numbers along field margins and expect to see populations rise… Read More →

Sugarcane Aphids in Grain Sorghum of the Texas Coast – 4/28/2017

Posted on by

The sugarcane aphid is now being found in grain sorghum fields of Calhoun, Refugio and Victoria Counties.  However, I have yet to see this aphid in numbers greater than 5 per leaf.  I expect their numbers will increase over the next few weeks and we will see economic levels in May. Several effective economic thresholds have been suggested for this pest.  I think all of them are similar and will result in field treatment at about the same time. To manage the sugarcane aphid, choose from these thresholds:… Read More →

Corn and Sorghum Hybrid Trial Results

Posted on by

The results of the Corn and Grain Sorghum Hybrid trials have been published by the Texas A&M AgriLife Extension Service. Each of these documents contains the results of hybrid trials conducted in South and Central Texas.  These trials are conducted by County Extension Agents in grower fields.  Most are toured on Crop tours during the growing season. 2016 Uniform Corn Hybrid Trials  2016 Uniform Grain Sorghum Hybrid Trials Results from other variety and hybrid trials can be found HERE
