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
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
The 2013 rice harvest may be one of the most anticipated harvests in recent years due to the long season. Let’s hope that growers are rewarded for their anticipation. As a recap, to my knowledge, the earliest rice in the state was
During the 2011 growing season Chris Main, Bob Hayes, Tom Barber, Dan Reynolds, and myself put together a defoliation guide to cover Tennessee, Arkansas, and Mississippi. The folks at LSU have a similar guide for cotton in that state that
The time of year has arrived that growers are getting the itch to terminate irrigation applications in cotton. In a normal year, cracked bolls are present at the present calender date; however, cracked bolls are currently the exception rather than
As is typical for this time of year, bollworm pheromone counts were higher this week, particularly in the Delta. These moths are presumably those that developed in corn ears, and will now be seeking out hosts for another generation, likely
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
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 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
Trap counts were generally steady to slightly lower this week compared to last week for both bollworm and tobacco budworm. As has been the case all year, counts are higher than in 2012 but slightly lower than long-term average catches.
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 rice crop in Mississippi continues to move forward. In addition to several acres moving to the heading growth stage, there are fields that are being drained. Draining typically means harvest is two weeks away. I am anxious to see
For the second week in a row, tobacco budworm counts are higher than average for this time of year. Bollworm catches were fairly typical for this time of year, so in non-Bt crops where both pests develop (like soybean), a
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
Trap counts for tobacco budworm were sharply higher this week in the MS Delta for the first time this year. Bollworm counts were also somewhat higher in the Delta compared to last week. However, from a historical perspective bollworm counts
