A Maturity Group IV and V variety trial was conducted in Verona, MS at the NMREC during the 2015 season. Yield and disease data are included in the attached report for all entries contained in the trial (RoundUp, Conventional and LibertyLink).
A Maturity Group III variety trial was conducted in Verona, MS at the NMREC during the 2015 season. Yield and disease data are included in the attached report.
Field evaluations of the Maturity Group IV entries in the MSU OVT were conducted at each of the locations where trials were planted (Brooksville, Clarksdale (n=2), Falkner, Longwood, Raymond, and Stoneville (n=3)). Entries were observed for their reaction to the diseases
The MSU OVT soybean locations were rated for disease during the 2015 season. Multiple diseases were rated at multiple locations. In the past, Cerospora leaf blight and frogeye leaf spot have been the two main diseases rated. In 2015, Septoria brown spot as well as target spot were included as well as a green stem rating. Phytotoxicity, following an accidental fungicide application, was rated in the Maturity Group IV early and late entries at one location.
The cultivars contained in the Mississippi State University Official Variety Trial (OVT), as well as a few added cultivars, were field-evaluated for their susceptibility/resistance to stem canker. Trials were conducted in Stoneville with toothpick-inoculated plants during the 2015 season. Tables contain the average ratings (on a 0-9 scale) as well as an assessment of resistance to stem canker (R, MR, MS, S) based on the ratings conducted.
The On-Farm Soybean Variety Demonstration Program is conducted using a set of varieties with proven performance. These varieties are grown in a production setting on various soil types and management systems around the state. Demonstration sets for both maturity group
The soybean variety trial ratings from the North Mississippi Research and Extension Center (NMREC) are included (MG III, IV, and V). The yield publication from NMREC will be posted at a later date. As in the past, plots were rated for Cercospora leaf blight (CLB) and frogeye leaf spot (FLS). However, this year, Septoria brown spot (Septoria) and target spot were also rated when the diseases were present. Green stem ratings were conducted for the Maturity Group IV early and late varieties.
We had an App created that will allow you to review the program and register straight from your Smart Phone for the 2015 Mississippi Row Crop Short Course Nov. 30th – Dec. 2, 2015 at the Cotton Mill District in
This effort lists those corn hybrids which have demonstrated superior productivity in the Mississippi Corn for Grain Hybrid Trials. No other source tests as many hybrids representing today’s market. Thus, there is no better barometer for you to judge hybrid performance and improve your ability to select the best for your farm.
The 2015 Delta area/Bolivar Co. Rice Meeting will be held at the Bolivar Co. Extension office on November 5, 2015. Mississippi rice producers, industry professionals, and other interested parties are invited to listen to presentations from MSU research and Extension
Find below the Preliminary version of the 2015 On-Farm Rice Variety Trial. During 2015, small plot rice variety trials were conducted near the following locations; Choctaw, Clarksdale, Hollandale, Ruleville, Shaw, Stoneville, and Tunica. Variety trial data is presented segmented by
Late-season soybean rust observations occur on almost an annual basis. Even though the majority of the soybean crop has escaped yield loss as a result of soybean rust again for the 2015 season, determining the extent of the disease in MS as well as potential locations where the fungus could overwinter continue to be an important part of the monitoring/scouting program. At present (9/22), soybean rust has been detected in 41 counties.
A field training regarding late-season soybean diseases will be held in Monroe County, MS on Tuesday, September 15 beginning at 5:30 pm and ending with a meal at a local restaurant. The diseases discussed will likely include: charcoal root rot,
Soybean diseases continue to be observed throughout the MS soybean production area. The number of counties (13, as of 9/4/2015) exhibiting soybean rust has increased over the past several days. However, low levels of infection have been observed at most locations. Frogeye leaf spot, Cercospora blight, target spot, and stem canker also continue to be observed.
We have had numerous calls over the last 2 weeks about caterpillars in peanut from all around the state. In every case, the calls have involved a complex of multiple species including bollworm/tobacco budworm, cutworms, armyworms, saltmarsh caterpillar, loopers, and rednecked peanut worm.
An agronomic crops field day will be held at Stovall farms, west and north of Clarksdale on Oakhurst Stovall Road. The field day will be held at Mr. Pete Hunter’s farm shop beginning at 10 am. MSU Extension Specialists will be present to discuss topics in corn, cotton, grain sorghum, peanut, rice and soybean.
There has always been a struggle with properly defining the correct cutoff for spider mites in cotton in the Mid-South region. For years we always loosely considered Node Above White Flower 5 (NAWF5 = Cutout) and 650 heat units the
We have been getting calls on loopers showing up in soybean for about 2 weeks. In recent days there have been reports of defoliation exceeding 20% or numbers exceeding threshold in some areas in the central to southern part of the state. The bulk of our soybean loopers typically show mid to late August or even into September so this is a little early but certainly not unusual. Soybean loopers are migratory and work their way north each year from southern latitudes. Early arrival could be due to a number of reasons.
The diseases present in the soybean crop have increased over the past several weeks. Cercospora blight and frogye leaf spot continue to be observed throughout much of MS. Fungicide phytotoxicity continues to be one of the hot topics of the 2015 season with numerous fields having received specific fungicide products that resulted in a foliar injury due to the extreme temperatures.
Over the last week we have been getting a lot of calls about extremely high bean leaf beetle numbers. Most calls have come from the Northwest Delta region of the state. We have actually made bean leaf beetle targeted sprays on a number of acres in recent days. Yield loss is caused by defoliation and less frequently by pod feeding
The MSU-DREC Rice Producer Field Day will be held in conjunction with the annual Mississippi Farm Bureau Federation Summer Rice Grower Meeting this year on the afternoon of July 30 at the Capps Center in Stoneville.. The Farm Bureau meeting
Week 5 Scouting Report Graduate Student Nick Bateman is running a weekly insect scout line in soybeans for part of his PhD project. We will be reporting his numbers weekly on the blog. Only insect pest that are being found in
Phytotoxicity as the result of applying fungicides that contain an active ingredient that produces an “injury” to soybean leaves has been observed this year. Large areas of fields or entire fields in an area with observable interveinal chlorosis should be observed for the presence of a specific disease. Observing root systems as well as cutting into the main stem to expose the vascular tissue should help tell the difference between many soybean root diseases and whether or not a disease is present.
The soybean disease situation has not changed much over the past week, but as the crop matures more diseases will likely be observed throughout the state. At present, brown spot, frogeye, the mystery disease, and a few other minor issues can be observed in most soybean fields.
Stink bugs consisted of Brown, Green, and Southern Green stink bugs, with Green and Southern Green Stink bugs making up 75% of the total stink bugs caught. Loopers are starting to show up in R3 and later soybean in all counties listed but are in low numbers. We also were flushing numerous corn earworm moths in several fields in the Delta region.
