Crazy top downy mildew has been observed in numerous grain sorghum fields over the past two weeks. The general symptoms associated with the disease can oftentimes be confused for herbicide injury as well as a nutrient deficiency. Fields with grain sorghum that may have stood in water for an extended period of time may have become infected by the soilborne fungus.
Choosing a foliar fungicide product for either a common fungicide application at a specific growth stage in the absence of foliar disease or in the presence of disease should be based on the soybean variety planted. Widespread fungicide resistance to the strobilurin fungicides in the MS soybean production system within the frogeye leaf spot fungal population may ultimately change how we use fungicides. Choose a fungicide product based on whether or not frogeye will occur in a susceptible variety rather than choosing a fungicide based on price.
More growers are implementing different “tassel shot” inputs as part of their corn management program. Wet weather and other issues may further complicate application timing of such inputs. This article discusses whether specific timing makes a big difference or not?
Over the past several years a root disease of soybean has been observed throughout MS as well as adjacent states. Presently, research is being conducted to determine the causal organism(s) involved in the disease. On Wednesday (May 27), plants in several fields were observed throughout the Inverness as well as Leflore County (Quito) area. The fields have historically had an issue with this particular root disease. Some of the general symptoms and signs of the disease and a general update regarding research project are included in this particular post.
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
Mississippi State University will be hosting 5 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, weed identification, and
For the most part the Mississippi wheat crop is clean with regards to foliar diseases. However, some important issues are occurring that need to be addressed with regards to Fusarium head blight, stem maggot feeding, and general herbicide injury as these three issues can easily be confused with one another at the field level.
Mississippi State University will be hosting 5 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, weed identification, and herbicide systems. There will be numerous hands on displays of insects, weeds, nutrient deficiencies in all major row crops, and fertilizer characteristics. CEU’s Provided: Nutrient Management = 1.5, Integrated Pest Management = 3, Crop Management = 1
Wheat diseases can be observed in almost any wheat field throughout the season. However, when wheat moves beyond the tillering growth stages scouting for the presence of foliar diseases should be conducted. Many, but not all of the foliar disease encountered in MS can result in a yield loss. But, additional issues encountered in wheat fields can oftentimes be easily confused for foliar diseases.
While we wait for the fields to dry up enough to get the 2015 planting season underway, here are a few peanut-related issues to pay attention to going into the season. – Jason Sarver • Inoculant usage continues to be
Updated Tuesday March 10, 2015. Added several new fungicides to the pdf file;Mar.16.update2.azoxystrobin Strobe 2L which has a comprehensive label for field crops, vegetables, turf, and ornamentals. Trevo, (22.9% Azoxystrobin, for use on corn, cotton, rice, and soybeans). Updated Tuesday March
The previously scheduled Mississippi Soybean Promotion Board seminar dates in Tunica, Verona, and Macon for Wednesday (2/25) and Thursday (2/26) have been CANCELED due to the potential for inclement weather over the next 36 hours. Future dates will be listed on the Mississippi Crop Situation Blog and locations will likely not change. Please stay tuned for further announcements.
Stripe rust was detected in wheat in Washington County, MS in the wheat variety trial plots. Wheat fields in MS should be scouted at this time for the presence of stripe rust. Fungicide applications with products in the triazole (DMI) class of fungicides will prevent spread of the disease and in some cases where the disease has occurred and been observed in a wheat field may protect yield.
I have been surveying growers, extension folks, consultants, and industry personnel over the last few weeks and it seems that the consensus is that we are going to significantly increase peanut acreage in the 2015 growing season. I think the
Find attached the agenda for the 42nd Annual Delta Ag Expo to be held in Cleveland, MS on Wednesday, January 21 and Thursday, January 22, 2015. We hope to see you in attendance at the Bolivar County Ag Expo Center.
Green stem disorder can be a sporadic issue from year-to-year and field-to-field. In the current blog post a survey is attached whereby individuals can answer five basic questions on their thoughts and opinions regarding the presence of green stem.
Disease severity was rated for each of the OVT soybean entries at all locations planted during 2014. Varieties were rated using a 0-9 scale where 0=no disease and 9=severe disease symptoms. The attachments on this blog post contain the Maturity Group V early and late entries.

Boll rot appeared to be a common occurrence in numerous cotton fields at the end of the 2014 season. However, not all boll rot can be attributed to bacterial blight, especially in situations where the disease was not observed prior to harvest. Secondary fungal infection can ultimately obscure the observable boll symptoms associated with bacterial blight. Keep this in mind when scouting fields at the end of the season as bacterial blight boll lesions can oftentimes be obscured by secondary fungal invaders.
Variety trials were rated at the NMREC to determine the sensitivity of MG IV and V soybean varieties to frogeye leaf spot as well as Cercospora blight. Varieties were using a 0-9 scale where 0=no disease and 9=severe disease symptoms. Yield data will be available in a few weeks as this post only contains the analyzed rating values for the varieties contained in the trial at Verona.
The Mississippi Entomological Association and the Mississippi Association of Plant Pathologists and Nematologists will be holding their joint annual meeting on October 20-21, 2014 at the Bost Extension Center at Mississippi State University. The meeting is open to all. Registration
