Over the last 10 days I have had several calls about stink bugs in small corn. There have been some fields treated, however, at this time it has not been widespread. Stink bugs damage small corn by feeding through the
It almost goes without saying that weather conditions over the past few weeks have delayed cotton planting. Some growers in the south Delta will likely begin planting operations where field conditions permit over the weekend. However, a 50% chance of
Over the past week I have continued to receive calls regarding the fungicide application restrictions in wheat. The specific wheat pre-harvest intervals are set to reduce the likelihood of a residue issue at the elevator. I do realize there has
Fortunately, young corn can sustain severe physical injury without suffering yield loss, because the growing point is below the soil surface. However, you need to wait 5 days or more to fully evaluate recovery or potential stand loss.

Following are a few hybrid suggestions for dryland Grain Sorghum or milo production in Mississippi.

Increasing populations of glyphosate-resistant and other herbicide-resistant weed species demand we adapt our corn weed control systems to address specific issues and prevent new ones. This may require you to implement strategies for a specific weed, plan on multiple herbicide applications, and improve your application timing.
Strong winds sand-blasted young, emerged corn plants in many fields this week. Fortunately, corn can sustain considerable vegetative damage during early growth stages without limiting development or yield.
Currently, the wheat crop continues to be mostly disease free. The majority of the wheat crop is heading to flowering depending on the geographic location within Mississippi. At present, the two most prevalent diseases are leaf and stripe rust.
Cotton planting in Mississippi will begin next week as weather conditions allow. Some small acreage has been planted as growers set planters; however, weather conditions up to this point have not been ideal for planting cotton. In the table below,
We are beginning to see stink bugs show up in some wheat fields in the delta. It is not uncommon to find stink bugs in wheat after head emergence. However, it takes extremely high numbers to cause economic damage to heading wheat.
Over the last 5-7 days aphid numbers have started crashing in wheat fields around the state. Our wheat test in Starkville went from several hundred per row foot on April 1st to less than 10 on April 4. Many consultants and dealers have told me they are seeing the same thing. A lot of this can be attributed to parasitized aphids from Lysiphlebus testaceipes (small parasitic wasp) but other cases may be contributed to various diseases that will take out aphid populations.

Tillage decisions for crop changes There are about two-thirds the acres planted in annual crop production in Mississippi than in the circa 1980 era. Annual Row Crop Harvested Acres The eighteen Delta or partial Delta counties account for 80% of
Mississippi Wheat Disease Update and Fungicide Decisions At present there is little to no disease in the Mississippi wheat crop. On Monday, low levels of powdery mildew were detected in a research plot in Stoneville. In addition, low levels of
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
Identifying off-target herbicide injury may be difficult when a definitive pattern is not readily apparent, substantial acreage is involved, or distance is considerable. This article gives some guidelines and photos to help identify glyphosate drift on wheat, so that you can manage appropriately.
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
Seems like every grower meeting we go to, we are hearing more and more about wild pigs destroying crops in some areas of the state. There are some producers that are even switching what crops they grow soley based on damage from wild hogs.
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.
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
