The North Mississippi Research and Extension Center’s Agronomic Row Crops Field Day on Thursday, August 7 will present the latest research to the area’s row-crop farmers and consultants. The field day will be from 8 a.m. to 1:30 p.m. at the Lee County Agri-Center Magnolia Conference Center on Highway 145 South in Verona.
“It ain’t over till it’s over!” Amazing as it seems, several producers have not laid poly pipe. After the five plus inches of rainfall we received last week, some producers are questioning the need to lay pipe this late in
Corn is not immune to yield loss until physiological maturity occurs. However, it is not nearly as vulnerable during late reproductive stages. This article includes a chart which should substantially help assess the risk of potential corn yield reduction during late reproductive stages.
Bollworm moth counts were up sharply across the state this week, so higher bollworm larval pressure should be expected over the next 1-2 weeks. Southwestern corn borer counts were high in Quitman, Tallahatchie and Leflore counties, but low elsewhere. Most corn
Foliar corn diseases continue to be observed throughout MS. Even though common rust, gray leaf spot, northern corn leaf blight, and southern corn leaf blight continue to be observed at low levels, additional diseases have been encountered over the past two weeks.
This past week we encountered the following situation. A Grower irrigated a silt loam field utilizing a surge valve. When he checked his moisture probes neither the 6” nor the 12” Watermark™ sensor had moved. What’s going on? After careful
Considering the abundant rainfall during June and the corn crop progressing closer toward maturity, many are wondering whether additional irrigation may even be needed. This article discusses how to make that and other late-season irrigation decisions.
Bollworm catches were similar to the previous week while tobacco budworm counts continue to slowly rise. Neither is particularly high for this time of year. Southwestern corn borer counts were up sharply this week, with a few traps in the
Foliar corn diseases continue to be observed throughout the MS corn crop. Common rust, gray leaf spot, northern corn leaf blight, and southern corn leaf blight are all present at low levels throughout the Delta. As of Wednesday (June 25, 2014), southern corn rust had only been observed in southeastern MS (Forrest, George, Greene, Jackson, Perry, and Stone counties).
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. We encourage you to visit http://www.youtube.com/watch?v=46sSLFBUrh8 and view the video before continuing. Phases
The importance of soil moisture sensors is becoming more evident as we continue forward this growing season. Today (Monday, June 16th), we received a call regarding sensor readings that were assessed early this morning. The following are the data discussed in this scenario.
Row crop irrigation needs are ramping up and one of the tools we can use to better assess soil moisture is Watermark sensors. This article describes how to analyze the data generated by sensors to help you better schedule irrigation.
Bollworm trap catches were up in the Delta region this week to levels about normal for this time of year. Most bollworm eggs will be laid in corn at this time when many corn fields are at silk stage. University research
To date this has been a fairly light corn disease year. However, some lesser observed diseases, such as anthracnose leaf blight can be observed on the lowest leaves in some corn fields. Common rust, northern corn leaf blight, and to a much lesser extent southern corn leaf blight can also be observed in some corn fields.
There are several caterpillar pests that commonly infest field corn in Mississippi. These include corn earworm, fall armyworm, and southwestern corn borer.
Bollworm trap counts were higher in Lowndes county this week, but all other locations were similar to the previous week. Tobacco budworm catches remain at very low levels throughout the state. Southwestern corn borer counts were also very low throughout
On June 9, leaders from the Mississippi Soybean Promotion Board, key personnel from the Mississippi State University Extension Service, and stakeholder organizations a part of the Delta Sustainable Water Resources Task Force formally announced a series of summer irrigation “Turn Row Talks†to be held across the Delta during the month of July for producers to attend local, on-farm demonstrations of water conservation efforts being implemented and utilized by growers in their respective areas.
Over the last few days I have started getting calls about fall armyworms showing up in soybeans. We see some of this every year, and it is primarily related to larvae moving off of a grass host after a Roundup application
Bollworm catches were lower in the Delta this week but steady in Northeast MS. Tobacco budworm catches were negligible in all areas (Table 1). Southwestern corn borer counts were also low throughout the state, so early corn that is now
More and more corn growers are applying various management inputs around tassel stage in order to improve efficiency and corn productivity. This article discusses how crop physiology affects the appropriate timing and crop response.
Every year at some point during the season we seem to hit a rainy spell where it seems to rain at some point every day and we have showers widely scattered across the state. It started raining last Wednesday and we have had some rain everyday since then and it is currently raining in Stoneville right now (Monday morning). With that, the questions start about how long you need to spray before a rain to get acceptable control.
A corn, cotton, peanut, and soybean field day is scheduled for June 17th at the Delta Research and Extension Center in Stoneville, MS. The general theme of the field day will include pertinent information for mid-season row crop issues.
Bollworm trap catches were down in the Delta region this week from last week, while tobacco budworm catches were higher in the Delta (Table 1). There was minimal change for catches of either species in Northeastern MS. This is the
I have gotten numerous calls about slugs this year in all crops but lately in cotton and soybean. Slug problems usually start on corn then soybeans then cotton in our area. This is only because we typically plant in this order. We have had isolated problems with slugs since 2004, some years worse than others.
The dates for the 2014 Scout Schools have now been set. We will be providing detailed information on identification, biology, thresholds, and management of the major insect and disease pest of Mississippi row crops. These trainings can also be used to renew your insect and disease consultants license and CEU’s for Certified Crop Advisors will be provided at each. The meetings will also serve as In-Service training opportunities for MSU-ES agents as well. These trainings are great for the experienced and the inexperienced.
