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
Pheromone trap counts for bollworm were stable this week in the Delta while rising in the Northeastern region of Mississippi. Based on several weeks of fairly high bollworm moth catches, protection is likely needed in many fields against bollworm throughout the
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 Mississippi Department of Agriculture and Commerce releases value of production estimates each year. Below is a list summarized the value of several Mississippi agricultural commodities. For more information click on the link below. Mississippi Value of Production Estimates 1.
Over the past several weeks blooms have become commonplace in most Mississippi cotton fields. Many of these fields were blooming at or just after the 4th of July. Once cotton begins to square and more so once bloom begins, nutrient
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
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.
After rising for several weeks, bollworm pheromone trap counts decreased some in the southern Delta region while slightly increasing in the hills and North Delta regions this week. This likely indicates that we are at peak moth flight for this
In just the last 3-5 there have been several reports of bollworms now showing up at threshold numbers in soybeans in the Delta region of the state. In many other areas of the Delta folks are reporting flushing extremely high
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.
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.
There will be an impromptu sorghum midge scouting field day at the MSU Delta Research and Extension Center in Stoneville tomorrow (July 14, 2015) at 8:00 am. We will meet at the Capps Building at 8:00 am and then travel directly
The diseases encountered throughout the MS corn crop continue to be the same. Northern corn leaf blight and southern corn rust continue to be the two most talked about diseases. Annually, as the corn crop matures, NCLB appears to increase since lesions reach their most mature expression. Southern corn rust has been observed in 19 MS counties to date (July 11, 2015). Fields where the disease has been observed typically contain a light dusting of rust.
Tarnished plant bug populations have continued to be high over the last couple weeks in the Delta. A lot of the cotton is at or near the bloom stage when it is most attractive to plant bugs.
Field days scheduled for next week will highlight crops with new and developing herbicide and insect trait technologies. These field days will be held at the following locations: Brooksville – July 15 The Row Crop Technology Showcase at Brooksville will
Bollworm trap numbers in the Delta and Hill regions have continued to increase some over what was reported last week. Southwestern corn borer numbers are still very high in some areas of the Delta and sprays may be needed in
Considering the abundant rainfall during the July 4th week and the crop progressing closer to maturity, some are likely wondering whether if the 2015 corn crop is finished. This article discusses how to make that call and determine timing for irrigation termination.
Beginning July 6, 2015 Mississippi producers in eligible counties may enroll in the Cotton Transition Assistance Program (CTAP). The deadline for enrollment is Sept. 30, 2015. CTAP is for farms with former cotton base acres that are physically located in
Stink bugs consisted of Brown, Green, and Southern Green stink bugs, with Green and Southern Green Stink bugs making up 95% of the total stink bugs caught. Egg masses of both Kudzu Bugs and Stink Bugs have been seen in both regions in R3 and later soybean.
Numerous fungicide trials were conducted during 2014 to determine the efficacy of specific fungicide products as well as tank mix components at managing Cercospora leaf blight and frogeye leaf spot. Included in this post are ratings as well as yield for eight total trials conducted in Starkville (2) and Stoneville (6) during the 2014 season.
The incidence of soybean diseases in the MS soybean production area has increased over the past 10-14 days. Aerial blight, Cercospora blight, frogeye leaf spot, Septoria brown spot, target spot, and Vein necrosis virus have all recently been observed in commercial soybean fields throughout MS.
Corn diseases have started to be more commonly observed throughout the MS corn production area. Given the time of year in both calendar date and crop stages (post-tassel) several corn diseases are being observed more often. Northern corn leaf blight, southern corn leaf blight, and Diplodia ear rot have all been observed over the last two weeks. Southern corn rust made an appearance earlier than normal; however, the disease is considered to be at extremely low levels at this time even though five counties (Adams, Claiborne, Coahoma, Forrest, Stone) have been observed to contain infected corn plants.
We are now beginning to get numerous calls from around the state about sugarcane aphid infestations. Populations range from very low to well above threshold with treatments becoming more common this week. At this time aphids are being found in the Hills and
