Bollworms have certainly been the hot topic in cotton and later planted soybeans this year. This flight started in some areas the week of July 4th and peaked in the Southern Delta around July 10-15. Since that time it has
Numerous soybean varieties were observed to be severely affected by target spot during 2016. Symptom expression on the specific varieties may be difficult to tell apart from other diseases. Some of the varieties were not commercially available for the 2017 season. However, in some rare situations some of these varieties may be planted and will likely respond this season in a similar fashion to what was observed during 2016 as a result of the continued wet weather during the 2017 growing season.
Several foliar diseases have increased in incidence throughout MS over the past several weeks. Root diseases, such as sudden death syndrome, taproot decline and one field of stem canker continue to be observed in the production system. The current foliar disease situation is outlined in this particular post.
We saw a surge in RBSB numbers a few weeks ago into March planted soybeans that were approaching R6 growth stage but since then populations have moderated. Just in the last few days we are now seeing another big surge moving into
Entires for the 2017 Mississippi Soybean Yield Contest are due on August 1, 2017. Entry Forms can be found at the Mississippi Soybean Association website: www.mississippisoybeanassociation.com. Some entries have been getting sent back if sent to the address on
You are welcome to attend the Row Crop Update at the Mississippi Agricultural Industry Council Conference. The conference is hosted at Perdido Beach Resort in Orange Beach, Alabama on Wednesday, July 26.
The bulk of our soybeans are going to outrun the current bollworm flight. Over the last 5-7 days we are getting reports of above threshold numbers of bollworms in soybeans. This is pretty much restricted to the soybeans that are R2-R4. We
We have sprayed several fields in the last 2 weeks for RBSB’s. To date, most fields have been late March planted beans that are R5.5-R6 growth stage. Most of the fields so far have been south of Hwy 82, but
The soybean disease situation continues to change throughout MS depending on growth stage situations in each field. Over the past week root diseases have been commonly observed. The first soybean rust of the season was observed in southwestern MS on kudzu.
Over the past several years, fungicide pre-mix products have dominated the marketplace. Keeping up with the specific chemical classes within each product can present a challenge. Included in this blog post are some information to aid in making fungicide decisions.
Limited soybean diseases have occurred throughout the MS soybean production system. Observations of Septoria brown spot and taproot decline have been quite common this season. Lesions that result from herbicide injury have also been commonly observed, but should not be cause for concern.
Getting more calls everyday about low numbers of Redbanded Stink Bugs (RBSB) in R2/R3 soybeans. Many are asking about what to mix with a fungicide to take them out. Before jumping out too quickly, consider this, I would suspect very little
Over the past week calls have started to be received regarding the automatic fungicide application in soybean. On-farm, large plot trials were conducted during 2015 and 2016 to assess the benefit of several different fungicide products and to reevaluate the automatic application timing. At present, we believe that a mixed mode of action fungicide, or one that provides more than one mode of action would be more beneficial than the stand-alone strobilurin (QoI) fungicide application that has become popular over the past decade.
In 2009 Redbanded stink bugs (RBSB) were treated in numerous areas of the state but numbers crashed in 2010. In 2013 there were a few fields treated and then they essentially were a non-issue until 2016. We have been hearing
Mississippi State University will be hosting 4 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, and herbicide symptomology. There
By now I am sure everyone has seen the pictures of the flooding occurring from recent rains in across the river in Arkansas and Missouri. Compared to those states, Mississippi has fared pretty well in regards to flooding of young
Herbicide mixtures can have a large influence on barnyardgrass control with glyphosate.
Target spot management in soybean production systems remains a hot topic going into the 2017 season. The environment that occurred during late July and early August 2016 made us respect a disease that is often “out of sight and out of mind”. Fungicide data from two efficacy trials conducted during 2016 are included in this blog post.
Labeling for new auxin herbicide products detail requirements that either restrict application or require buffers between the treated field and sensitive areas or susceptible crops.

New auxin herbicide products have associated websites, which are considered extensions of the federal labels, that list additives and herbicides approved for mixture.
Target spot was one of the main diseases that occurred during 2016. Normally a disease of little consequence in soybean as well as cotton, severe target spot outbreaks were observed in both crops. Making decisions regarding the occurrence of target spot during 2016 are difficult since the environment during key plant growth stages was the most important ingredient for the occurrence of target spot last season.
Observing the preplant intervals for 2,4-D and dicamba prior to planting is important.
