2018 Corn Grain Hybrid Tests in Tennessee

Author:  Comments Off on 2018 Corn Grain Hybrid Tests in Tennessee

As promised, our 2018 TN corn grain hybrid trial data has been finalized and is now available. Follow these links for the full pdf and all excel tables.  We are still working on getting our web-friendly, sortable, and searchable tables up on search.utcrops.com.  I’ll post to the blog as soon as they are available, which should be sometime next week.

Due to persistent rain delaying harvest at some locations, our soybean variety trials data is likely still a week or two away, but will be posted as soon as possible!

Cotton – Thinking Ahead About Bollworms

Author:  Comments Off on Cotton – Thinking Ahead About Bollworms

It is uncertain how big our moth flight will be this year. As usual, bollworm moth catches have been generally low to this point. However, you can expect activity to slowly increase, with a peak in moth activity occurring the last week of July and the first week of August. With the decreasing efficacy of pyrethroid insecticides and increasing tolerance to some Bt toxins, you should plan on using Continue reading

Moth Trapping Results and Other Reminders

Author:  Comments Off on Moth Trapping Results and Other Reminders

A reminder that weekly moth tap catches for corn earworm (bollworm), tobacco budworm, and southwestern corn borer can be found under the quick links menu under Moth Trapping Data.

With the exception of southwestern corn borers (SWCB) in some locations , we’ve not been catching many moths. Now would be a good time to scout the whorls of any non-Bt corn for the presence of corn borers. Remember that the treatment threshold during the whorl stage is when 5% of plants are infested with SWCB.

Also remember that UT Pest Guides are available at http://guide.utcrops.com/. They provide the latest information of pest identification, sampling, and management in a mobile-friendly, app-like format.

Palmer Amaranth Management: Frequent Rain Making it very Difficult

Author:  Comments Off on Palmer Amaranth Management: Frequent Rain Making it very Difficult

This weather pattern has Palmer amaranth management in a terrible fix for many fields in West Tennessee.  The rain that has occurred on an almost daily basis for over a week in many areas has delayed early POST herbicide applications.  The forecast for rain into June looks to be a similar pattern. There will likely be a very small window to spray until the first week of June for numerous fields.  Palmer amaranth is growing quickly and now is often in the 1 to 3” range where a PRE was used and 10 to 14” range in fields where no PRE was used.  Continue reading
