Research Update (July 15, 2017)



Diligence Technologies Inc., West Tennessee

EVENTS FROM THE PAST MONTH:

We have spent a good portion of the past couple of months trying to catch up on trial establishment.  Frequent showers meant that we had few full weeks to get things done, so we have been working where and when we can.  As a result, trial establishment was farther behind than in any year in recent memory.  Several trials had to replanted due to excessive moisture with a few even requiring three or four attempts before we finally got a good stand.  As always, the crew (Jesse, Kevin, and Jackson) did a heroic job of making sure everything got done.
 

CROPPING SEASONS:

Wheat is almost over for this season.  We are finishing up post-harvest data collection (seed weights, etc.) at present.  Disease pressure was pretty good in the fungicide trials and you could see the benefits of a well-timed foliar application.

We have corn trials at almost every imaginable growth stage.  Planting dates on yielded trials range anywhere from mid-April to mid-May.  Our later trials (generally fungicide trials planted intentionally late to increase disease pressure) are just beginning to enter the reproductive phase and corn fungicide applications will begin in mass next week.

Applications will also begin soon in soybean fungicide trials.  Applications at R1 will likely be next week with R3 applications a couple of weeks later.

Cotton trials began the year very slowly.  With excessive moisture and reduced amounts of heat and sunshine, the cotton struggled to get a good start.  Stands were sometimes thin and the crop in general was less than impressive.  The good news is that growth has improved substantially with the increased heat and sunshine over the past month.  It is finally time to break out the growth regulator and try to slow things down just a bit.

 
GREENHOUSE ACTIVITIES:

The greenhouse is officially closed for the summer which is a good thing.  The greenhouse is heated which makes it a great place to work during the winter.  However, the cooling fans can only do so much in summer and it is difficult to find volunteers to go in there in July.

Keep us in mind for your greenhouse needs later this fall.  We should have it back in operation in October.


TOURS:

Thanks to everyone who has stopped by for a visit so far this spring.  However, with trial establishment slower than normal, much of the prime viewing time for plots is still to come.  Several tours have been rescheduled for a little later in the season.  As always, just let us know when you will be in the area.  We always enjoy getting to spend time with friends.


PEST INFO:

Preemergence weed control has been generally good this spring as frequent showers allowed for herbicide activation in the soil.  Postemergence herbicide injury has been above normal as crops had little opportunity to “harden off” during the early spring.  Even our normal maintenance applications tended to show burn on the foliage.  Probably not a significant issue, but it does not help make the plots look good.

Disease activity is still pretty low right now in the fungicide trials.  It usually takes a while for grey leaf spot in corn and frogeye leaf spot in soybeans to build and the crops are still relatively young.  For those wanting to look at fungicide trials, late August has traditionally been a good time for viewing.

Insect pressure has been fairly light this year with the exception of thrips on cotton.  However, we generally have some excellent opportunities to test insecticides on late-planted soybeans.  Let us know if you need a late bug trial and we will work something out.

 
We are very thankful to those who have sent trials our way so far this season.  We still have some ground available for an evaluation late this summer or early fall.  I tell folks all the time that it is a rare September that we do not plant a few corn or soybean trials.  Just let us know how we can be of service.

Research Update (February 13, 2015)


Diligence Technologies, Inc., West Tennessee

We would like to welcome Heath Scott to the Diligence Technologies family (shown above).  Look for Heath around the trials and plot tours this summer.

We would also like to thank Paul Kennedy and Ben Wiggins (Helena) for dropping by to tour the greenhouse facilities last week.

Upcoming Events

Gin Show (Feb. 27-28) - Look for us at the Gin Show in Memphis on Friday, Feb. 27.

West TN Sportsmen's Night (March 12, 5:00 p.m.) - For those of you who live around west Tennessee, let me invite you to the West TN Sportsmen's Night at Englewood Baptist Church in Jackson.  The event will include a wide variety of interactive events, seminars, and food for the outdoors enthusiast.  The featured speaker will be Jimmy Sites.

Cropping News

Greenhouse work continues through the winter months.  Right now we have trials running with such varied crops as tomato, soybean, and turf.  Our heating, lighting, and irrigation systems seem to performing well now that most of the "bugs" are out of the system.

Winter wheat progress remains slow but steady.  The cold weather we received right after wheat planting did not allow much wheat growth prior to winter.  Wheat continues to progress with a solid stand, but some warm weather and a little nitrogen will likely do it a world of good.

As usual, we do have extra wheat planted for those wishing to run fungicide trials in the spring.

With winter weeds spread across the fields, we are reminded that burndown trials will be coming up soon.  Please let us know if you have burndown trials that need a home this spring.

Pest News

Target spot (Corynesporna cassiicola) in cotton continues to make some news in west Tennessee.  A relatively new pest for this area (past couple of summers), target spot appears to have the potential for significant cotton damage.  The presence of only a few "spots" will often cause a cotton leaf to drop and substantial defoliation of the crop has been observed.  Some fungicides do appear effective on the disease, but exact rates and timings are still being studied.

Thrip resistance to some of the seed treatment insecticides in cotton has reached the point that only imidacloprid is being recommended for the coming season in Tennessee.  Testing is underway for alternative treatments and methods of cotton thrip control.

As always, we are thankful to all you who have sent us your business in the past and blessed to be able to serve you.  Let us know if there is anything we can do to help out in the coming season.

Seest thou a man diligent in his business?  He shall stand before kings…

Research Update (December 12, 2013)


Diligence Technologies, Inc., West Tennessee

One more season is almost in the books.  With a few exceptions (such as the wheat, follow-crop, and weed control trials we have scheduled to run through the winter), all the trials are out of the field and the reports have been sent to their rightful owners.

In general, 2013 was wet, cool, and late.  Planting was delayed in many cases (we almost seem to have lost the month of May) due to frequent rains.  Much of the cotton that we did manage to plant had to be replanted (sometimes more than once).  The summer was generally mild (which was good for the corn, soybeans, and researchers), but the cotton could have used a few more heat units to push it along (particularly the later planted cotton).  Corn, soybeans, and early-planted cotton (that lived) all yielded very well.  Our biggest issues at the end of the season were getting the beans to dry down and getting the late-planted cotton open and defoliated before frost.  Quite a change from 2012 when the finished the season about a month and a half earlier.

We have put our wheat to bed for the winter and don't anticipate much activity there until early spring.  As usual, we have planted extra wheat for those fungicide trials we don't know about yet.  Let us know if you have some of those in hand.  We have also started marking out areas for early burndown trials next spring so let us know if we need to save you a nice, weedy spot.

Weed pressure this past season was dominated by resistant pigweeds (no big surprise there).  While we had plenty of moisture to activate herbicides, the frequent rains shortened the residual of our soil products substantially.  Insect pressure from some of our more consistent pests (stink bugs, plant bugs, soybean loopers) was pretty light this season.  The pests were there, but the populations did not build as I have seen them in some years.  The one big exception was thrip pressure in cotton.  We had more early thrips this past season than I can ever remember.  One new arrival this year was kudzu bug.  We had the "honor" of making the first "official" find of kudzu bugs in Shelby county this past season.  While the kudzu bug populations were pretty light this year, I am told by other researchers that we should have plenty to test on next year.  Disease pressure was fairly typical.  Both corn and soybean diseases were a bit late this year (you would think they would have come sooner with all the rain), but we had plenty of pressure in the end to get some good ratings.

Meeting season is just around the corner.  Our January calendar looks like this:

Beltwide Cotton Conference (Jan. 6-8, New Orleans, LA)
Conservation Systems Cotton and Rice Conference (Jan. 15-16, Tunica, MS)
Southern Weed Science Society (Jan. 27-29, Birmingham, AL)
National Association of Independent Crop Consultants (Jan. 29-Feb.1, New Orleans, LA)

Please let us know if you plan to make any of these meetings.  I would love to have the chance to catch up with our old friends.

Allow me to take this opportunity to thank those of you that let us be a part of your research program this past season.  We were truly blessed.

Research Update (June 8, 2013)


Diligence Technologies Inc., West Tennessee

It was basically a week of grinding out trials.  We missed the rains on Thursday (which may be the first ones we have missed this year), and spent the week playing catch-up.  Considering the slow start to the season, we may be playing catch-up for quite some time.

Yielded cotton trials are largely off and running.  Now we are switching our attention to soybeans as well as weed and bug trials.  We have a long line of those to get started.  Efforts are slowed to some extent because we are having to go back in and clean up fields again in order to initiate trials.  Some of the fields are pretty wooly since it has been a while since we did our initial field preparations.

The pest problem of choice right now is extreme thrip pressure in cotton.  Judging for the counts obtained in our thrip trials, this could very well be the heaviest thrip population I can recall.  Almost every cotton trial I have that is out of the ground received a postemergence application for thrips this past week.  Would not be surprising if we get to do it again next week.

Thanks to our friends from Syngenta Seeds and Brandt that stopped by for visits this past week.

Also, thanks to all our customers for their patience as we have slowly limped into this season.  Most things have been behind schedule but we will keep working to get your data rolling in as soon as we can.
