Cotton Insect Update: July 10, 2015
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.
Insect Pheromone Trap Counts, July 10, 2015
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
Soybean Scouting Report: 7/6-7/10/2015
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.
2014 Frogeye Leaf Spot and Cercospora Blight Foliar Fungicide Trials: Trial Data
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.
Soybean Disease Update: July 5, 2015
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 Disease Update: July 4, 2015, Southern Rust Observed in Five Counties (UPDATED @ noon)
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.
Soybean Scouting Report: 6/29-7/3/2015
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.
Pheromone Trap Counts, July 2, 2015
The biggest change for this week is the rise in southwestern corn borer trap counts. High numbers were spotty in the Delta with one Leflore county trap recording 668 moths in a week. Coahoma, Quitman and Sunflower counties were the
Southern Blight of Peanuts – It’s Arrived
Southern blight, has been found on peanuts in several areas of the state this week. Southern blight is a plant disease that attacks the crown and below ground parts of peanuts. It causes the plant to wilt and die or
Mid-Season Rice Update
I would like to call this a midseason rice update, but in actuality we have rice in Mississippi ranging from one leaf to late boot in places, but most of the rice crop should be at or reaching mid-season. Similar
Mississippi State University Turn Row Field Day: Clarksdale, MS July 9, 2015
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.
Automatic Soybean Fungicide Applications: Timing, Product Choice, Rates in Product Combination
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.
Rice Stink Bug Update: June 19,2015
As some of the earliest planted rice is getting close to heading, it is time to start thinking about rice stink bug. We have been sweeping headed grass around the Delta for the past two weeks to determine what kind of populations are around.
Soybean Insect Management: The Most Common Questions and Myths…
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
MSU Scientists Study Tie Between Insecticides and Bee Health
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
Peanut Growers: Tropical Storm Bill
Posted June 16, 2015. The low pressure in the Gulf has turned into tropical storm Bill. It is now predicted to impact the coast further south than it was several days ago. Updated forecasts by NOAA indicate that the primary
Choose Fungicide Product for Soybean Fields Based on Variety Planted
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.
Soybean “Mystery Disease” Update
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.
MSU-DREC Rice Field Day – July 30, 2015
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
Mixed Bag of Early Season Caterpillar Defoliators in Soybean
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.
Soybean Planting Progress
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
When Should I Start Irrigating My Corn?
The recent stretch of dry weather has prompted much conversation about the proper time to initiate irrigation for corn. This scenario usually generates a lot more anxiety than necessary because early season wilting is certainly not something we are very accustomed to.
Use a Sound Corn Nitrogen Strategy to Combat Rainy Weather
Abundant spring rainfall can create havoc with corn nitrogen management by delaying fertilizer application and also promote massive nitrogen loss. These strategies should help enhance crop response during challenging conditions.
Seed Treatments, In-Furrow Sprays, and Granular Insecticides: What to do in Mississippi Field Corn
Although every major field crop we grow in Mississippi is responsive to at planting insect protection; field corn is perhaps the most consistent. Why is this?
