Stink Bugs in Soybeans 7-1-25

Posted on by

Stink Bug numbers really went up in the past week with some fields having over 100 bugs per 100 sweeps. Most of the stink bugs we are finding in soybeans are red banded stink bugs and this is a worst case since this bug is much more damaging than the other stink bugs. The economic threshold for most stink bugs is 36 per 100 sweeps, but for the red banded stink bug, the published threshold is 16 per 100 sweeps and I would probably treat around 12 per… Read More →

Cotton IPM Update 5-30-25

Posted on by

Cotton Maturity ranges from squaring to bloom.  We are still finding fleahoppers in some fields. In fact our insecticide test had mostly of adult cotton fleahoppers and some Verde Plant bugs this morning before the rain.  The treated plots had very few nymphs but the untreated cotton had adults and nymphs at a 1:1 ratio. We are seeing control with all of the products at 7 days after treatment, but the nymph counts for Bidrin was was not different from the untreated nymph counts. Once you find 1… Read More →

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 →

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 →
