Included in this blog post are a rice disease calendar. Information presented in the calendar deals with the most commonly observed rice diseases throughout the MS rice production area. In general, the occurrence of diseases on rice will depend on the planting date, general field history as related to previous crop, and the environmental conditions throughout the season.
On Tuesday, May 24, 2016, soybean rust was detected on kudzu in Amite, Pike and Wilkinson counties in southwest MS. The observations of soybean rust yesterday mark the earliest appearance of the disease by a little more than 6 weeks as compared to the past. No specific management practices are suggested at this time.
Included in this blog post are updated disease calendars for MG IV and MG V soybean to aid in scouting plant diseases. Keep in mind that several variables can impact the time of year when specific diseases are observed. Planting date, variety susceptibility, number of years a particular field has been in soybean, and prevailing environment can all play a role in when a disease is observed.
Increased observations of foliar wheat diseases have occurred over the past two weeks. Leaf rust, stripe rust and Septoria leaf blotch have been commonly observed throughout the state. In addition, with the current environmental conditions (humidity, rainfall) and the general growth stages observed, the potential for Fusarium head blight (scab) may be similar to as occurred during the 2015 season.
Wheat diseases have been few and far between this winter. Little wheat was planted in the fall of 2015. However, in some key areas, rust diseases (leaf and stripe) as well as bacterial leaf streak have been observed on wheat.
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, and herbicide symptomology.
Environmental factors play a substantial role in nitrogen fertilization for wheat producers in the Mid-south. This article gives guidelines for application timing, fertilizer sources, rates and other important practices which may improve your wheat productivity.

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,
The following is a short video clip showing sugarcane aphids building on the flag leaf of mature grain sorghum. This will have to be addressed in this field to avoid complications with harvest equipment. Options are Transform at .75 –
There have been numerous calls and questions about Dectes Stem Borer over the last few years. It seems that numbers are increasing each year. This is not surprising when you consider the biology of the insect coupled with an increase in soybean acres in MS.
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.
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
There have been numerous reports lately of high numbers of corn earworm and sorghum webworm in grain sorghum. I have heard some reports of numbers as high as 10X threshold. It is critical to scout and treat as needed to control these pest. There are three species that make up the headworm complex in grain sorghum; the corn earworm (bollworm), fall armyworm, and the sorghum webworm.
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
When it comes to scouting for sorghum midge I have found that very few people have the confidence to accurately find them. Most believe if they are not finding them that they must be missing them or doing something wrong. The
Rice leaf blast has been observed most of the rice season throughout the MS Delta. In addition, neck blast has been observed in some fields that were infected early on with the blast fungus.
