An agronomic crops field day will be held at Cliff Heaton farms, just east of the intersection of Highway 61 and Highway 6. The field day will be held in the cotton field on the south side of the road. MSU Extension Specialists will be present to discuss topics in corn, cotton, grain sorghum, peanut, rice and soybean.
For the most part, the corn disease situation has been quiet. Limited occurrences of common rust and northern corn leaf blight have been observed in some Delta fields. With the cooler and wetter conditions encountered early in the season it is possible that some uncommon diseases could be encountered.
Questions continue regarding fungicide products to be used at the R3/R4 application timing. The most important decisions should be made based on the specific variety planted in each field since frogeye leaf spot is resistant to the strobilurin class of fungicides meaning that stand-alone strobilurin products are no longer effective against the disease. See the information contained within this blog post regarding fungicide products, effective rates of products in pre-mix combinations and the effectiveness of some fungicides on managing frogeye leaf spot.
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.
As rice approaches reproductive growth stages, it is less likely to recover from injury due to off-target herbicide movement.
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.
Barnyardgrass is resistant to five herbicide modes of action in rice.
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.
Three more opportunities exist for ag-related personnel to attend the Mississippi Soybean Promotion Board sponsored seminar series on nutrition management, nematode sampling and management, and irrigation practices. Meetings are scheduled next week in Tunica (2/25; 9 am), Verona (2/26; 9 am), and Macon (2/26; 2:30 pm).
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.
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.

The 2014 Delta area/Bolivar Co. Rice Meeting will be held at the Bolivar Co. Extension office on December 4, 2014. Mississippi rice producers, industry professionals, and other interested parties are invited to listen to presentations from MSU research and Extension
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.
