Key Issues to Address at Corn Planting
Corn planting can be a hectic time, but it pays to take care of business when planting corn. Here are some keys to a successful start and optimal corn yields.

During 2013, several fungicide trials were conducted to determine the benefit of vegetative growth stage timings in corn. Two large plot trials were conducted in east MS with the help of Dr. Dennis Reginelli. In this blog post, the results of two large plot trials were presented from one nonirrigated and one irrigated field setting. Small plot trial data will be reported at a different date.
RISER irrigation approach reduces water use by 50% while maintaining yield potential.
The results from the Second Annual Future of Ag Graduate Student Competition are included in this post.
I have been fielding calls from many producers and consultants within the last week about zinc applications with corn planting season shortly around the corner. Zinc deficiency in corn generally occurs early in the season (V2-V5) and manifests itself by
Over the last several years there has been a media blitz surrounding the decline in honey bee populations around the globe. It seems like the science changes daily as to cause of the problem. Most believe it is a complex
Included in this blog post are ratings collected for frogeye leaf spot as well as Cercospora blight from the 2013 Maturity Group V soybean variety trials. Trials were conducted in Brooksville, Clarksdale (irrigated), Falkner, Longwood, Olive Branch, Raymond, Stoneville (clay and loam). The conventional/LibertyLink trial was only conducted at the Brooksville, Falkner, Longwood, and Stoneville (clay) locations. Ratings were collected based on a 0-9 and are presented from each location for each variety so a range of ratings is available across all environments encountered during the 2013 season.

Attached please find the agenda for the Delta Ag Expo in Cleveland, MS. Make careful note that the dates of the meeting have changed from previous years due to a minor scheduling conflict with the Bolivar County Exposition Center.
Attached in this blog post are the variety trial results from the North Mississippi Research and Extension Center in Verona, MS. Harvested yield as well as variety response to natural infection from Cercospora blight and frogeye leaf spot are included in the associated tables.
Each year the Mississippi State University Extension Service conducts numerous on-farm variety trials in cotton and other crops. These data are intended to complement small plot official variety trial (OVT) data that are also generated by Mississippi State University personnel.
Variety selection is one of the most critical management decisions associated with soybean production. Factors such as soil type, planting date, irrigation capabilities, row spacing, harvest capacity, and other crops grown all can influence the decision for selecting an appropriate
As you look over your fields this winter, be thankful for the tons of potassium (K) present in every acre. It is the most abundant mineral macro-nutrient on earth, which is good because most crops utilize large quantities of it.
The 2013 Row Crop Short Course will be held at the Bost Extension Center on the campus of Mississippi State University from December 2 – 4, 2013. The 2013 Row Crop Short Course will begin with an irrigation symposium hosted
Virus-infected soybean material has been observed almost statewide this season. The high numbers of bean leaf beetles can be blamed for some of the observed viruses; however, bean leaf beetles are not the only insects that can vector soybean viruses between plants. This specific blog update presents information on the three most commonly encountered soybean viruses in the MS soybean production system.
Soybean disease questions still consider to be raised throughout MS. Even though soybean rust has been detected in 45 counties to date it appears we will have another season where yield losses as a result of soybean rust will be extremely limited and may only have occurred in a handful of fields. When making plans for next year consider sampling for nematodes in light textured soil classes. In addition, planting a frogeye susceptible variety in several years in a continuous soybean system may increase the likelihood of frogeye causing substantial yield loss.
It has often been said that cotton defoliation is more art than science. This thought is further nurtured when harvest aids perform differently under seemingly similar conditions. As with any pesticide application, many factors come into play when determining harvest
Foliar diseases of soybean continue to be observed throughout the MS soybean production system. Over the past week additional counties containing soybean rust have been observed throughout the state. Stay tuned to information on the Crop Situation Blog regarding additional counties with soybean rust infected plant material should management suggestions change.
Soybean looper has started to show up in soybean and a few applications have started in some fields. We have several good options to manage soybean looper and all of them should be considered. Belt has become the go to insecticide for looper control in a lot of situations over the last couple of years.
Now that early planted beans are drying down quickly and insect pressure is increasing on late planted soybeans in some areas, many are asking when it is safe to quit spraying insect pest in soybeans. For most pest in soybean
Numerous questions over the past few weeks regarding how well certain fungicide chemistries are managing frogeye leaf spot. Attached please find preliminary rating data from Starkville and Stoneville on how well particular products are managing observable symptoms of frogeye leaf spot. Additional data to follow as we continue to rate plots.
Two upcoming peanut field days offer the latest research recommendations and a chance to see some research/demonstration plots. The first field day will be held in south Mississippi, at Lucedale, the other in north Mississippi, at Clarksdale. Lucedale The Lucedale
Numerous diseases continue to be reported from throughout the MS soybean production area. Frogeye leaf spot continues to be the main foliar disease observed. Additional soybean rust was reported from Adams County this past week. However, since low levels of the disease continue to be reported the suggestion remains that farmers wait and watch the available information and allow soybean to get as close to reproductive developmental stages before making a fungicide application.
This last week I found early leaf spot in the Greater Columbus, Mississippi area. For information and images on how to identify early leaf spot, please see: https://www.mississippi-crops.com/2013/08/12/early-leaf-spot-of-peanut/ and https://www.mississippi-crops.com/2012/09/05/early-leaf-spot-found-in-the-greater-aberdeen-area/ Early and late leaf spot are major defoliators of peanuts
Synopsis: Is caused by a fungus, Cercospora arachidicola. Defoliates infected leaflets fairly quickly. Is one of the reasons, along with late leaf spot, for the development of the traditional two week spray schedule in established peanut growing areas (see Figure
