Managing Late Season Stink Bugs in Mississippi Soybean
Over the last month we have had numerous questions about terminating stink bug applications in late season soybeans. Typically we manage stink bugs until near harvest but there are several things to consider before making an application to control stink bugs in beans beyond R6 growth stage.
Market Update – Sept. 13, 2013
Cereal Grains & Soybeans (by: Brian Williams) The big news this week is yesterday’s WASDE report release (recap here). While many were expecting corn yields to be revised lower this month, yields were actually revised higher to 155.3 bu/acre. This was bearish
Sudden Death Syndrome Look Alike Part I: Red Crown Rot
Red crown rot has been identified in additional fields in east MS throughout the 2013 season. Prior to 2013 only two counties had been identified as having red crown rot. However, three additional counties have been added this season (Clay, Newton, Union). Red crown rot symptoms can be misdiagnosed as several other diseases, including sudden death syndrome (SDS).
Soybean Irrigation Termination
Determining when to terminate irrigation in soybean can be difficult. When making this decision, the goal is to make sure that adequate soil moisture is available to ensure that the soybean seeds reach maximum size. Terminating irrigation too soon can
Foliar Soybean Disease Update: August 31, 2013
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 Control in Late Soybeans
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.
Yield Loss from Defoliators in Soybean and Insecticide Termination
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
Frogeye Leaf Spot Fungicide Preliminary Data (Updated 8/30/2013)
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.
Soybean Irrigation Termination Turn-Row Field Day
Terminating soybean irrigation too early can result in lower yield due to decreased seed size. At the same time, irrigating when the crop no longer needs water can be a waste of time and resources. On Friday, August 30, 2013
Soybean Disease Update: August 18, 2013
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.
Crop Market Update – Aug 16, 2013
Cereal Grains & Soybeans (by: Brian Williams) Two bullish reports this week have helped boost prices for corn and soybeans. While many analysts were expecting an increase in corn production in this month’s World Agricultural Supply and Demand Estimates (WASDE), USDA
Bean Leaf Beetle Problems in Mississippi Soybean
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
Mississippi Kudzu Bug Update: 8/14/2013
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
August Supply and Demand Report Recap
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.
Market Update – Aug 9, 2013
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
Not Everything is as it Seems: Fungicide Phytotoxicity and Plant Diseases
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.
Kudzu Bug Update: 8/3/2013
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.
Stink Bugs Picking Up in Soybeans
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
Soybean Frogeye Leaf Spot: Management Decisions for the Disease Following an R3/R4 Strobilurin Application
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.
Bollworm Applications Starting in Soybean
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
Bollworm Flight Later Than Normal But Now Starting
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
