Over the last week I have received several calls of very high aphid numbers in wheat. The two species being found are Bird Cherry-Oat aphids (BCO) and Greenbugs. I have had reports of treatable levels of Greenbugs being found but
Our warm and humid Mississippi climate makes nitrogen (N) fertilizer management challenging. Let’s review the basics about N terminology as various product claims fly about with some puzzling promotional material being used. Be sure that you know what is being
March established cotton’s all time high at 227.00 cents during the delivery period while May posted its life of contract high at 219.70 cents. Thus, the contract highs for three consecutive months; March, May and July 2011, all posted highs well above the two dollar mark.
One of the objectives of this program is to identify key production limitations, so the Mississippi State University Extension Service and Experiment Station can better direct efforts to develop innovations for our specific problems. This is a summary of such limitations documented during the past few years.
Corn is quite unique because much of its potential productivity is determined during the planting process. Thus, corn is often much more responsive or dependent on variables implemented during the planting than other Southern crops. This article gives planting guidelines for enhancing corn profitability.
As producers prepare for spray applications this growing season, it is imperative to consider proper spray nozzle selection. As ground speed increases, the orifice size of the nozzle must be increased to maintain the desired GPA. A larger orifice naturally produces larger droplets which equates to poor coverage with contact herbicides. With this in mind, it is recommended to make spray applications at a reasonable ground speed that allows for the use of a spray nozzle that will produce a medium droplet size conducive for contact herbicides.
USDA released it’s March World Agricultural Supply and Demand Estimates (WASDE) report this morning. At this time in the marketing year few wholesale changes are typically seen in the report for U.S. summer crop production and use. This came to
During the production season of 2010, much of the peanut producing area suffered harsh drought conditions. This led to reduced yields and quality problems on last years crop, and will have lasting effects into this season. Dr. John Beasley, Peanut
The natural condition of most Mississippi soils is to become more acidic over time which reduces crop yields. From 1989 to 2009, just over half the soil samples analyzed by the MSU Extension Service Soil Testing Laboratory had pH values
The cotton market offers no rest for the weary as it continues to run over anything or anyone that dares to put a lid on it. The May contract has taken over as the lead month and also assumed the price leadership role with its climb above two dollars.
A precision agriculture workshop has been scheduled for Friday, March 11, 2011, in Hattiesburg, MS. Producers, agri-business, and extension are all welcome to attend. There is no registration fee, but please register so that we can have a count for
The original Best Management Practice (BMP) for managing nutrients to maximize profitability and minimize potential environmental issues is soil testing. This time of year is always exciting for Mississippi farmers; we’re past the winter (maybe. . .) and tractors are
Last year was a challenging year for insect pests of rice in Mississippi. In general, we experienced higher than normal populations of rice water weevil, rice stink bug, and fall armyworm. Luckily from the rice water weevil standpoint, the two
This update covers rice burndown considerations, hybrid insecticide seed treatments, and 2011 USDA Outlook Agriculture Forum – Rice Planting Intentions.
Sulfur in Mississippi Crop Production Sulfur is required in fairly large quantities by most crops. It is an essential building block in chlorophyll development and protein synthesis. Sulfur is also required by the rhizobia bacteria in legumes for nitrogen fixation.
Calcium and Magnesium For Mississippi Crops Calcium (Ca) and (Mg) magnesium are positively charged secondary nutrients. They are generally adequate in most Mississippi soils with favorable pH and organic matter levels. They affect acidity when applied to the soil, and
The 2010 Row Crop Short Course was held at Mississippi State University on December 6 – 8, 2010. As we expanded the Short Course in 2009, we also have adopted technology to record the oral and visual portions of the presentations.
In Mississippi, the rice water weevil is the most important early to mid season pest in rice. Three years of research have shown that foliar pyrethroid applications provide variable results, and may not always provide acceptable control.
Cotton futures hit 194.55 Friday, surmounting the all time high of 190.00 cents, established in 1864, during the U. S. Civil War era.
With snow melting and warmer temperatures on the way, burndown should be taking place next week. I have included a video presentation for rice winter weed control. You can stream the video by clicking on view in a popup. The file can also be downloaded by clicking on Rice Winter Weed Burndown below.
Cotton producers in Mississippi planted approximately 425,000 acres of cotton in 2010. This was a 33% increase in acres compared to 2009. Approximately 5% of cotton in MS was planted to transgenic single gene Bt varieties and 90% of cotton acres was planted to dual toxin transgenic Bt varieties. The most popular varieties planted in 2010 were
With the current commodity prices, some suggest that the 2011 crop be ‘insured’ by applying micronutrients. Is this good policy for Mississippi field crops? These essential elements are required by plants in very small amounts: boron, zinc, molybdenum, iron, manganese,
There are several keys to successful wheat nitrogen fertilization in Mississippi. Split application of nitrogen fertilizer is likely more important for wheat than any other crop, including corn. This is because wheat nitrogen fertilization occurs during the wettest months of the year – in a high rainfall, warm regional climate conducive to nitrogen loss.
For the past 15 years the only herbicide program that most producers have known was the use of glyphosate in Round Ready® crops. With glyphosate-resistant weeds becoming more of an issue there has been an increase in demand for alternative control options.
