UPCOMING EVENTS:

SWSS Weed Contest, Knoxville, TN (August 5-6, 2026) 

UT Cotton Tour, Jackson, TN (September, TBD)

 

CROPPING SEASONS:

Foliar fungicide applications in corn and soybeans are largely done with a few exceptions for later-planted trials or those with later application timings.  Disease pressure is off to a good start, but the weather going forward will likely have a greater influence on disease development than the rains we have received so far.

Our weed trials are in many different stages ranging from completed to just initiated.  All our crops for insect trials are established and we are monitoring some of these to determine the proper application timing.

 

UPCOMING TRIAL REMINDERS:

WINTER WHEAT

Wheat planting in west Tennessee normally runs from about October 15 to November 10.  We need to start working on any trials that focus on the fall (i.e. any trials that have treatments at planting or before winter dormancy).  We can wait a bit later on trials that have treatments targeted at next spring.  We typically have extra wheat to work with and spring trials can be established at that time.

Please let us know soon about any wheat fertility trials you might be considering so that we can match the location and maintenance program to your needs.

 

WEATHER INFO:

We finally managed to get all our current field trials underway.  June and the first half of July presented a challenge with frequent showers that often made planting and spraying difficult.  However, I continue to hold to the belief that too much rain is better than too little.  With too much rain, progress is slow.  With too little rain, progress is stopped.  And if most every August is any indication, we will be asking for rain again soon.

 

PEST INFO:

We have had no shortage of weeds this season.  In fact, one of our biggest challenges has been cleaning up fields in order to get other types of trials established.  The frequent rains made the weeds grow fast and made it difficult for us to get in the fields and clean them up.

Our major diseases (gray leaf spot in corn, frogeye leaf spot in soybean) have progressed well to date.  However, it is generally August before these diseases really come and on and we start to see which treatments are working.

We may be spraying cotton plant bugs before long.  At present, we are just waiting for “research grade” populations to build.  Insecticide applications to corn and soybean will be made later in the season.  It is generally beneficial to plant those trials late which tends to result in higher pest populations.

 

If you need a late trial this summer, let us know.  We can usually find a spot to run another trial or two.

EVENTS FROM THE PAST MONTH:

Once again Larry Steckle and crew put on an excellent weed tour at the experiment station in Jackson.  His is one of a few tours that continues to have good attendance in an era where tour attendance is declining overall.  As such, it is a great opportunity for us to catch up with old friends and learn what is on the horizon in the world of weed control.

 

UPCOMING EVENTS:

Milan No-till Field Day (July 23, 2026)

Agricenter Feast on the Farm, Memphis, TN (August 1, 2026)

SWSS Weed Contest, Knoxville, TN (August 5-6, 2026) 

UT Cotton Tour, Jackson, TN (September, TBD)

 

CROPPING SEASONS:

Except for possibly a few late soybean trials, all our yielded trials are finally in the ground.  Both May and June were filled with scattered and frequent rain showers that made planting progress sporadic.  We have managed to start a few weed control and insect trials along the way, but there are still several that remain to be established.  We even have a few cucumbers to plant for some late-season fungicide work.

 

GREENHOUSE ACTIVITIES:

Most of our greenhouse work is wrapping up now and barring some unexpected requests, we may be largely out of the greenhouse until this fall.  We appreciate all the greenhouse trial work this past season, but the logistics of conducting greenhouse trials in the heat of field season are quite challenging.  Maybe we can slow down in the greenhouse for a while and pick things back up in the fall.

  

UPCOMING TRIAL REMINDERS:

COTTON DEFOLIATION

Depending on the speed of cotton maturation and our original planting dates, we generally spray defoliation trials in late September and early October.  Therefore, if you are looking to get in a cotton defoliation trial this season, please let us know as soon as possible.

Also, do not hesitate to contact us even if you were not aware of the trial when we were planting cotton.  We have access to some large blocks of cotton that can be cut into research trials.  Just let us know before defoliation season so we can save you a spot.

 

WEATHER INFO:

As mentioned earlier, frequent showers have been a major challenge this spring.  While it certainly beats the alternative, it has also made us later getting some of our trials established.  Many thanks to those who have waited patiently for their trials to get established.

 

PEST INFO:

Weeds have been a challenge this season.  Many of the sites that were tilled early in the season require additional burndown and tillage to get new trials established.  This just makes everything go that much slower.

Insect populations seem to be building in cotton much better than last season.  Last year we had difficulty finding research grade populations of plant bugs.  At least for now, things are looking much better on the insect front for this season.

 

Let us know if you have any late trials that we help with.  It seems there is always room for one more.
