Bean leaf beetle numbers have been much higher than they have been in the last couple years. We have actually made bean leaf beetle targeted sprays on a number of acres this year. Yield loss is caused by defoliation and
Seems like we are adding new counties every week. We are now at 24 counties total with 16 of those having kudzu bugs found in soybeans. At this time we have actually treated a field or two for kudzu bugs in
Soybeans Soybeans also saw bullish news in the August WASDE report. Both planted and harvested acres were revised down by half a million acres from last month’s projections. Soybean yields were also revised down by 1.9 bu/acre to 42.6 bu/acre.
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
Cereal Grains & Soybeans Prices continued their downward slide for corn and wheat this week. Favorable weather has helped to keep new crop corn and soybean conditions rated 60-65% good or excellent. Meanwhile, many producers continue to empty grain bins
Phytotoxicity following a foliar fungicide application is not a commonplace occurrence in our soybean production system. In certain situations, the symptoms that express themselves when a fungicide application is made in the heat of the day can manifest themselves similar to characteristic foliar disease symptoms. Sudden death syndrome (SDS) is a common occurrence from the standpoint that we observe the disease annually but rarely does it impact yield and in fact we normally suggest that SDS simply means you’ve raised some great soybeans in that particular field. Keep in mind that SDS will only occur on light soil texture classes and normally not across an entire field as a situation such as phytotoxicity could.
The 2013 cotton crop looks respectable in many areas of the state. The National Agricultural Statistics Service rated 62% of the crop as good to excellent with only 6% being fair to poor. This crop continues to lag behind previous
Blast of rice was positively confirmed in three rice fields on Tuesday afternoon. Blast lesions are specific in that the generally form a diamond-shaped lesion on the leaf.
Cotton leaf spots have been observed in several fields again this year shortly after flowering. Positively confirming the particular disease is the most important event to determine a potential management scenario. The difference between the members of the “potash complex” as well as target spot are distinct, but numerous lesions need to be observed to positively identify the causal organism.
This week we added four new counties for positive finds of kudzu bug. All finds were in soybeans. This weeks new counties were Benton, Noxubee, Lawrence, and Issaquena.
Several insect pests have started to show up in cotton over the last couple of weeks. In most cases in the Delta, applications have shifted from targeting plant bugs to targeting plant bugs plus at least one other pest. In most of those situations, tank mixes with multiple insecticides are needed to control the whole complex. In this update, we will attempt to cover all of the current pests and highlight some control options.
Cotton irrigation has been on-going for the past four weeks and will likely continue three to four weeks depending on weather conditions. Watering schedules vary from grower to grower and field to field. In addition, watering schedules vary depending on
With the exception of the last three years, stink bugs have always Mississippi’s number one insect pest of soybean. There are many species of stink bugs in MS soybeans but the three predominate species are Southern Green, Green, and Brown
Frogeye leaf spot continues to be one of the main foliar diseases observed in the 2013 soybean crop. In several situations a fungicide has applied and frogeye continues to be an issue. In the current blog post several pieces of information are included to help aid decisions in whether or not a particular variety may be susceptible or resistant to frogeye. In addition, a table of the labeled fungicide products for use to prevent yield loss as a result of frogeye leaf spot are included.
With many consultants reporting flushing high numbers of moths over the last 7-10 days, bollworm larvae are beginning to turn up at treatable levels in some fields now. Over the last couple days I am hearing reports of treatments going out
Usually in Mississippi the major bollworm flight coming off of corn usually ranges from June 25-July 7th on average. We started getting our first calls out of the south Delta this week. Many consultants are reporting scattered worms and eggs
Corn fungicide questions continue to be made even in situations where corn has reached dent. In general, making a fungicide application at dent or later corn growth stages only pays off if excessive disease pressure is observed prior to the fungicide application being made. Moreover, making a fungicide application to a foliar disease tolerant hybrid will likely not pay off since the genes present in the hybrid should be relied on for preventing yield loss as a result of foliar disease.
Over the past two weeks increased reports of soybean diseases have been made from throughout the state. In addition, in southern MS, two more counties have been confirmed to be positive for soybean rust.
Over the last couple of weeks numerous calls have come in regarding layby herbicide programs. There are several options for layby programs and many have their own favorite program that they have been successful with in the past. I will
The Mississippi State University Extension Service in cooperation with Monsanto Company will host a pigweed field day near Robinsonville, MS on July 17, 2013. The field day location is just north of Tunica National Golf Course. A more detailed map
The Delta Research and Extension Center will host their annual Corn & Soybean Field Day on July 18, 2013. This year’s event promises to have even more learning opportunities for producers and agricultural professionals.
I have had numerous calls on kudzu bugs in the last couple weeks, mainly from the southwest part of the state. Kudzu bugs were found in 4 counties in 2012 in MS. In 2013 we have now confirmed 10 additional counties, in which 6 were found in soybeans. Since these initial finds in soybeans in Warren, Claiborne, Hinds, Yazoo, Stone, and Rankin Counties, it has become common for consultants to find 4-8 adults per 25 sweeps, in a few cases up to 10-15 in a couple of these areas.
The Soybean Minute is a new radio program that can be heard on the Mississippi AgriNews Network. These reports, sponsored by the Mississippi Soybean Promotion Board and the United Soybean Board, offer the latest information on soybean production in Mississippi.
Once again this season soybean rust has been detected early in July. A single infected leaf was discovered in a soybean sentinel plot in Pearl River County on Tuesday, July 9, 2013. Historically this is 4 days earlier than last season (2012) and 2 days earlier than the earliest occurrence of rust in MS that occurred in 2007 on kudzu. At present, no additional management scenarios are necessary. We continue to scout to determine how widespread infection may be across south MS.
Soybeans The 2013/14 crop saw a few changes from last month’s report should be considered slightly bearish even as the market moved higher. Planted acres were revised up 0.6 million acres from last month to reflect the June Acreage report. Harvested acres
