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 others may influence the decision of selecting an appropriate variety for profitable
Described below are the most common nutrient related issues that occur in Mississippi rice production and a few distinctive characteristics to key on when trying to properly identify each issue in the field. Nutrient issues in rice can take on
Yesterday we found our first southern blight* damage to peanuts for 2014. The timing is not unusual, we generally start finding the disease when the crop canopy closes. What is unusual is where on the plants the disease was found.
Populations of the white sugarcane aphid are expanding and increasing across the state. We have confirmed the presence of white sugarcane aphid in grain sorghum in 7 counties in Mississippi (Fig 1) and there are likely more. The counties where white sugarcane aphids have been found include Bolivar, Washington, Humphreys, Quitman, Panola, Tunica and Oktibbeha.
With water being one of the most expensive inputs of the rice producer, utilizing methods to limit the amount of water used makes economic sense. Adoption of multiple inlet irrigation has allowed producers to reduce water consumption. Water use with
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
Square retention is a critical component of early season plant bug management. I would strongly encourage you to take square retention counts along with your sweep net counts prior to bloom. Not only does this help in the decision making process of treating plant bugs, but it also helps you to get a better idea of how the products you are applying are working. Numbers alone can be deceiving when adults are steady moving into the field. When large numbers of adults are migrating into a field it is not uncommon to have as many or more plant bugs 4-5 days after a spray than you did before you sprayed and it still would not equate to a control failure.
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
I don’t have to tell any of you the amount of rainfall we have had over the last several weeks. Most of the rainfall we have receiving has been high intensity rainfall (i.e. all coming down at once). High intensity
Warm April weather in North Mississippi provides great growing conditions for sweetpotato plant beds. A few days near the 80s will have sweetpotato shoots pushing up the black plastic mulch that has been covering them since March. However, warm and
Wheat diseases remain extremely scarce throughout the MS wheat production system to date. No leaf rust, stripe rust, or Septoria have been observed to my knowledge. However, bacterial leaf streak has become a regular observation in most wheat fields.
Fungicides have become an important management alternative for diseases such as frogeye leaf spot. However, with the addition of the strobilurin-resistant fungus responsible for frogeye leaf spot, caution must be taken when applying fungicides to not increase the likelihood of fungicide resistance from developing. The specific characteristics of the main fungicide classes labeled for application in soybean systems are outlined. In addition, a table that includes the specific components of the pre-mix products when the labeled rates are applied is included.
by: Brian Williams and John Michael Riley Monday’s numbers from USDA National Agricultural Statistics Service’s Prospective Plantings report and Grain Stocks report came in near expectations. The Prospective Plantings report uses surveys of producers from February 27 through March 18 to estimate the upcoming acreage allocation. For
Just to prove that 2,4-D labels can be confusing, plantback restrictions were listed correctly in the previous post, but formulations were not specified.
With the cold, wet weather, many burndown herbicide applications were delayed. This has led to a multitude of questions on plantback restrictions for 2,4-D and dicamba prior to planting corn and soybeans.
Annual report of Mississippi Rice Promotion Board is now available online.
Control of glyphosate-resistant Italian ryegrass was reduced with glyphosate plus Select Max at reduced rates when combined with 2,4-D Ester and/or Clarity.

Fifty-three people attended the Delta Area Rice Grower Meeting in Cleveland on Thursday, Nov. 21st. In spite of the good number, many growers remained in the fields to take advantage of what is probably the last chance to get fall
On November 18th, a candidate for the Mississippi State University Rice Breeding position, will be giving a seminar in the Capps Classroom on the Stoneville campus at 10:30. We are excited about progress that our breeding program has made, and
Mississippi State University will host a rice grower meeting Thursday, November 21 at 12:00 noon at the Bolivar County Extension Office in Cleveland. The meeting will begin with lunch and will feature Experiment Station/Extension Service Personnel discussing problems that were encountered
Cereal Grains & Soybeans (by: Brian Williams) The September prevented planting acreage report was released by the FSA earlier this week. While the report did not contain many surprises with only minor changes from last month’s report, it does indicate that
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
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
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
