Boron is a micronutrient that plays a role in cell wall structure and the formation of proteins within plants. Boron deficiency is more common in younger leaf tissue toward the top of the cotton plant. Deficiency symptoms may appear as
Pheromone trap catches for bollworm, tobacco budworm and southwestern corn borer were very low throughout the state this past week. However, bollworm catches were slightly higher than last week, so we may be seeing the first moths of the next
As wheat harvest is being completed and we begin making marketing and future cropping plans it is important to understand seed laws pertaining to wheat. This article explains the ramifications of PVP and Patent protection pertaining to wheat seed.
We are having lots of questions concerning the proper set up of surge valves. First, please consider some of the basic terminology associated with furrow irrigation with surge valves. We encourage you to visit http://www.youtube.com/watch?v=46sSLFBUrh8 and view the video
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.
This is the first week this year I am reporting trap counts but we have had most traps out for at least 2-3 weeks. Overall trap catches have been average to light. This week, the trap catches for corn earworm
If you farm old traditional cotton soils, most likely you have recognized that irrigation water tends to run down the row, racing to the tail ditch. If you have noticed this, you have a “sealing soil”. If you are using
With irrigation season ramping up quickly, Mississippi State University Extension Service has lots of expertise and programs available to assist with your needs. One tool that we are using to better assess soil moisture and schedule appropriate irrigation is Watermark™
Abundant rainfall has soaked corn fields for extended time during April and late May, exposing nitrogen fertilizer to potential loss. This article gives guidelines for estimating potential N loss.
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.
Several calls have come in regarding early season herbicide injury in cotton to both myself and Jason Bond. It is not uncommon to see cotton injury from applications of Sequence or metolachlor products mixed with glyphosate and/or Liberty. Undoubtedly, the
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
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
Surface sealing in the Mississippi Delta typically occurs in soils that have a low clay and organic matter content but have a high silt fraction, i.e., most of our silt loam soils. Surface sealing, from an irrigation management standpoint, is
Last week Dr. Eric Larson wrote an excellent article dealing with corn irrigation initiation. At that time, a few growers had already begun to irrigate. Dr. Larson stressed the importance of accurately assessing soil moisture verses leaf wilting when determining
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.
Mississippi State University Extension is in the process of planning two soil moisture sensor field days for Summer 2015. Attendee will view demonstrations and presentations of the agronomic advantages of utilizing soil moisture sensors to trigger row crop irrigation presented
Over the last few weeks we have received numerous calls about brown stink bugs in seedling corn in the Delta region of the state. Stink bugs attack corn by feeding through the stem or even down in the whorl of small corn plants. Typically the area where they feed becomes chlorotic due to enzymes in their saliva.
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.
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.
