To keep each of the sections short I’ve separated the entire segment regarding fungicide application in corn into 5 general segments. 2011 marks my 5th season with Mississippi State University. Since I started this job on May 15 2007, one
Weekly pheromone trap captures from Northeast, Central and Delta regions of Mississippi are reported. Light to moderate bollworm pressure with very few tobacco budworms and beet armyworms caught during the week of May 12 to 18.
Several questions have come in this week regarding the effect of cold weather and moisture on cotton growth. Cotton is sensitive to cold temperatures as well as excessive soil moisture. Generally speaking, having one of these situations is made worse
In the last 7 days there have been numerous reports of extremely high thrips numbers infesting cotton fields across the state. Although nearly all cotton has an insecticide seed treatment on the seed, high numbers of adults are overwhelming the seed treatments in many cases.
Over the past few weeks I’ve received numerous calls regarding wheat leaves and heads that have gone from not presenting disease-like symptoms to presenting disease symptoms in a short period of time. In addition to leaf symptoms (see top photo),
Tremendous headway was made this week with regard to cotton planting. Planters started moving late last week as well as over the weekend. By Monday, planting activities for several crops were well underway throughout the state. While flooding is of
Many folks have inquired about specific information regarding wheat vulnerability to herbicides. This article specifically describes and contains photos to help identify the critical hard dough stage, when wheat is generally no longer vulnerable.
The reason for this post is to give an update on insect pests that we may be seeing in the near and distant future. First, we had several wheat fields around the Delta that had some fall armyworms. In addition, we are seeing a fair number of fall armyworms in whorl stage corn. I wouldn’t say the numbers we are seeing are anything of great concern, but the numbers are higher than we normally see this time of year. This tells us that fall armyworms are in the environment and capable of moving into rice. As the wheat is drying down, make sure to keep a close eye on field edges, especially those fields adjacent to wheat.
One of the current corn research initiatives at Mississippi State University is a project evaluating corn productivity to later than normal planting dates, particularly when grown with irrigation. The preliminary results may be pleasantly surprising for some growers stricken with stand loss or delayed by rainfall.
Floodwater from the Mississippi river and other drainages threaten to destroy many acres of wheat which are ripening and approaching harvest. Many are wondering if there are any methods to hasten wheat maturity or permit harvest before floodwater destroys the crop.
In the last 7 days there have been a few calls coming in about armyworms in wheat. Numbers have ranged from 1–12 per square foot. Mississippi has always used a threshold of 5-6 larvae per square foot through the milk
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.
