End of Season Pest Management Decision Making

Corn and Grain Sorghum harvest has begun on the Mid-Coast of Texas. Early yield reports are above average. While many Sorghum fields are no longer susceptible to the yield reducing impacts of insects, we must not forget the later fields. Stink bugs and headworms can impact sorghum yield and quality losses until hard dough or when the grain cannot be compressed between the fingers. Sugarcane aphids have been relatively low across the mid-coast this year with less than 30% of fields requiring treatment. Don’t forget these aphids after hard… 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 →

Sorghum of the Mid-Coast – May 5, 2017

Sorghum fields in Calhoun, Refugio and Victoria Counties should be scouted weekly for pest insects. This is especially true for the Sugarcane Aphid and Sorghum Midge.  We have ben finding sugarcane aphids in sorghum fields across the area but their numbers have been below threshold levels thus far. I have seen only occasional plants along the southern edge of sorghum fields with sugarcane aphids.  The most I have seen thus far is small colonies of less than 20 aphids on a less than 1% of plants. When scouting sorghum fields, I suggest marking… 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 →
