Corn Foliar Disease Update: June 24, 2011
At present there is still little to no foliar disease in the majority of the corn crop. Many of the calls I’ve received over the past 7 to 10 days have dealt with sun scald, herbicide injury or urea burn

Insect Trap Counts, June 23, 2011
Pheromone trap counts for bollworm, tobacco budwrom and beet armyworm were all similar to last week in all regions. Counts of tobacco budworm and beet armyworm are high compared to historical data, especially in the central part of the state.
Drought Stress and its affect on Corn Pollination and Early Grain Fill
Despite Mississippi generally receiving abundant yearly rainfall, we often experience substantial drought stress growing corn. The timing of rainfall and the ability of our soils to store moisture are critical to corn productivity. This article explains how drought stress and irrigation management may influence corn productivity during the early grain filling stages.
Insect Trap Counts, June 16, 2011
Pheromone catches of bollworm (corn earworm) came down slightly this week while tobacco budworm and beet armyworm catches are increasing, especially in Central MS. Southwestern corn borer traps indicate that the sewcond generation has begun. Most traps are still fairly
Mississippi Crop Progress Report: June 12, 2011
Week ending June 12, 2011 Released: 3:00 P.M., June 13, 2011 According to the National Agricultural Statistics Service in Mississippi, there were 6.5 days suitable for fieldwork for the week ending Sunday, June 12, 2011. Dry weather conditions are
Corn Foliar Disease Update: June 15, 2011
At present, low levels of foliar disease continue to be reported from some corn fields throughout the Delta. Over the past week more common rust has been identified throughout the corn canopy. I’ve received several telephone calls questioning whether or
Supply and Demand Report Recap
On Thursday the United States Department of Agriculture released its monthly World Agricultural Supply and Demand report (WASDE). The June report was the second that revealed projections regarding the current growing season for crops. The report continued the ongoing theme
Insect Trap Counts, June 9, 2011
Pheromone trap counts for the week ending on 6-9-2011 show higher tobacco budworm and beet armyworm counts from the previous week. Corn earworm counts were similar to last week. All three of these insects are at levels where treatable larval populations
After the Flood: Row Crop Replanting
MSU Extension Service and MAFES researchers have compiled the following suggestions and information regarding replanting and managing row crops after the flood. Also included is post-flood crop insurance information.
General Corn Foliar Disease Update: June 8, 2011
At present, and generally due to the hot and dry conditions, little if any foliar disease is present in the Mississippi corn crop. On Friday (June 3) I scouted fields in the Tchula/Thornton area. The particular fields were dryland corn
Insect Trap Counts, June 2, 2011
Corn earworm (bollworm) pheromone trap counts were higher this week, so larvae should be expected in vulnerable crops shortly. Tobacco budworm counts were also higher except in the Delta where none were caught this week. Southwestern corn borer counts are
County Maps of Herbicide Resistance in Palmer Amaranth from Mississippi
In an effort to aid Mississippi producers in their decision making process a statewide survey was conducted to determine where glyphosate and/or ALS-resistant Palmer amaranth was present in the state.
Scout for Stink Bugs in Corn During Ear Shoot Development
While we have quite a few corn fields beginning to tassel, many more are have a little ways to go. There is a period of about 10-14 days when ears shoots become visible or begin to bulge on the side
The corn fungicide dilemma: when should a fungicide be applied? Part V of V, preventing yield loss from foliar disease
Over the past 4 updates I’ve attempted to present data that suggests the best time to apply a fungicide is in response to a foliar disease that could potentially reduce yield. In many situations particular fungicide products are being touted
The corn fungicide dilemma: when should a fungicide be applied? Part IV of V, standability/lodging
Much has been made of the ability of strobilurin fungicides to prevent corn from lodging, typically towards the end of the season. Since 2007 I have received countless calls that have gone something like “we sprayed a field with fungicide
The corn fungicide dilemma: when should a fungicide be applied? Part III of V, green leaf material as measured by percent chlorophyll
Since 2007, fungicide products containing a strobilurin active ingredient have been suggested to increase plant “greenness†or allow the plants to stay greener longer in the field following a tassel (VT) application. Increased green plant tissue has been stated to
The corn fungicide dilemma: when should a fungicide be applied? Part II of V, irrigated versus non-irrigated situations
From 2007 through 2009 Mississippi State University extension and research personnel were involved in a large corn fungicide research effort funded by the Mississippi Corn Promotion Board. Except for situations where corn was planted on experiment stations (Brooksville, Pontotoc, Raymond,
Southwestern Corn Borer, Bollworm, Budworm and Beet Armyworm Trap Catch, 5-26-11
Weekly pheromone trap captures from Northeast, Central and Delta regions of Mississippi are reported. Catches indicate moderate bollworm pressure with very few tobacco budworms and beet armyworms caught during the week of May 19-26. Southwestern corn borer pressure is generally light
Insect Scout School Dates Set
This year there will be three insect scout schools provided. Each insect scout school will cover insect pests of cotton, soybeans, and corn. Scout schools are free of charge and open to everyone. Detailed descriptions of pest biology, sampling, and
The corn fungicide dilemma: when should a fungicide be applied? Part I of V, yield in the absence of measureable disease
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
Bollworm, Budworm and Beet Armyworm Trap Catch, 5-19-11
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.
Market Update
Commodity markets remain in a very volatile state – especially based on events over the past two weeks. The event that hits closest to home is the flooding. From a national perspective the planting delays for corn across the Midwest

As concerns mount about the potential damage to Mississippi crops from the flooding of the Mississippi River and its tributaries, many are left with more questions than answers. For those with crop insurance we are being told to remain in contact with
What to Expect from Later than Normal Corn Planting
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.
