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.
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.
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
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.
An agronomic crops turn row talk will be held at Cliff Heaton farms, just east of the intersection of Highway 61 and Highway 6 on July 9, 2015. The field day will be held in the cotton field
A series of field days will be held throughout Mississippi in 2015 which will highlight crops with new and developing herbicide and insect trait technologies. Field days will be held at the following locations: Dundee – Douglas and Chris Hood
Stink bugs consisted of Brown, Green, and Southern Green stink bugs, with Green and Southern Green Stink bugs making up 85% of the total stink bugs caught. Some small corn earworm larvae were found in very low numbers in the Delta region.
Weekly Soybean Scouting Report for Mississippi Hills and Delta Region 6/22-6/26
Pre-registration is now open for the upcoming Row Crop Technology Showcase events hosted by Mississippi State University. These events will be held at the following locations: Dundee – Douglas and Chris Hood’s farm – July 7 Brooksville – MSU Black Belt
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.
The upcoming Row Crop Technology Showcase events hosted by Mississippi State University have been mentioned a couple of times on Mississippi-crops.com; however, we now have a list of topics that will be covered at each event as well as credits
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.
This is a recycled article from 2012 and slightly updated but it fits well with recent calls. Sentences in italics have been added or updated since original posting. I have been getting quite a few calls about whether or not
By Keri Collins Lewis MSU Ag Communications STARKVILLE, Miss. — “Just mentioning bees and pesticides in the same sentence is sure to get a buzz,” said Angus Catchot, an entomologist with the Mississippi State University Extension Service. Media skirmishes about
This year we have seen tremendous population growth and expansion of Kudzu bugs from previous years. We have treated some acres already that were at threshold and I am confident that there will be many more to come based on what we are seeing around the state including the Delta region.
Due to the challenging weather this spring, we have been forced to adjust some dates for the upcoming Row Crop Technology Showcases. The event that was scheduled for Dundee on June 16 has been moved to July 7. The event
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.
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.
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
Over the last couple of weeks I have had numerous calls about caterpillar pest in young soybeans. Most of these have been concerning beans that are still in the vegetative stages (V2-V5). The species that are being found are bollworm, yellowstriped armyworm, green cloverworm, granulated cutworm, alfalfa caterpillar, cabbage looper, garden webworm, and yellowstriped armyworm.
Although the 2015 planting season started out slow, tremendous progress has been made to get this year’s crop growing. According to the USDA National Agricultural Statistics Service in Mississippi, 79% of the soybean acreage is planted as of the week
