This season’s corn crop, particularly that planted in early March, is extraordinarily early. However, it will still need additional irrigation or rainfall to finish the crop out. This article discusses crop progress and methods to schedule and terminate irrigation water for corn.
Interest in mid-season application of various inputs has certainly increased as we try to improve corn productivity through better management. This article discusses how corn physiology plays a primary role in determining corn yield response and appropriate management timing.
The DREC will be holding two separate field days, one for corn and soybean on July 19 and one for rice on July 31.
The United States Department of Agriculture’s World Ag Outlook Board released their monthly supply and demand estimates report earlier this morning. The report was the second round of forecast for the current summer (new) crops, which is the 2012/13 marketing
The biennial North Mississippi Research and Extension Center Agronomic Row Crops Field Day will be held at the Lee County Agri-Center, Magnolia Conference Center, Highway 145 South of Verona, on Thursday, August 9, 2012, from 8:00 a.m. to 1:30 p.m.
Bollworm and budworm pheromone trap catches are up some from last week, but bollworm catches are still far below typical catches for this time of year. Some sampling of corn and sweet corn has confirmed the low pressure. Once corn
Over the past few days reports of northern corn leaf blight and gray leaf spot have increased in the MS corn crop. However, common rust is still the only rust that has been observed in MS. Keep in mind that in some cases common rust, on the lowest leaves in the corn canopy, can take on the appearance of southern rust.
Over the past several weeks we’ve encountered tremendous hail damage in corn fields. Leaf shredding is one of the more common symptoms associated with hail injury and the greatest source of yield loss as a result of hail injury (see:
Over the past few weeks numerous maladies have been observed in corn that don’t require a management decision. One of our more common issues, purple leaf sheath, is simply present under the right environmental conditions and when nutrients become available for the organisms that produce the minor staining on the corn plant.
Corn fields in several areas of the state unfortunately took a beating from hail and wind associated with storms May 20-22. Several different types of damage may have occurred depending upon the type of storm, including hail damage, lodging and greensnap. This article will describe how much damage may have occurred.
When glyphosate was effective on most weeds, we were in a period of “weed controlâ€. However, over the last few years since glyphosate-resistant weeds have become so prevalent, we have entered a period of “weed managementâ€.
Scouting corn can be especially challenging. Looking for disease within the corn canopy can take a tremendous amount of time and should be done a little different depending on the particular crop stage encountered. Once an ear has set (post-tassel) focusing on the ear leaf and above is generally the best scouting method since protecting the ear leaf is important. I’ve included several descriptions and pertinenent information regarding some of the more commonly encountered diseases in our corn production system.
Sprayer cleanout after a herbicide application is a critical component to a successful herbicide application.
The corn crop appears to be much earlier this year than it has over the recent past. I’ve driven by numerous fields from south Washington County to north Bolivar County where almost 100% of the field has reached the tasseling
The insect scout schools for 2012 have been set. At each scout school we will go over biology, thresholds, and scouting techniques for each of the major pests of cotton, soybean, and corn. This is a great refresher for the
USDA released their monthly World Agricultural Supply and Demand Estimates report (WASDE) early this morning (May 10). The report is the first to highlight the new -2012- crop. The report revealed more corn and cotton available than analysts expected, while
An agronomic crops field day will be held at the R.R. Foil Plant Science Research Center in Starkville, MS on July 19, 2012 from 9 to 11 a.m. The field day will begin at 9 a.m. with field tours concluding
Dry early season conditions have prompted much conversation about the proper time to initiate irrigation for corn. This scenario usually generates a lot more anxiety than necessary because early season wilting is certainly not something we are very accustomed to.
A good rule of thumb is that the crop should be weed-free for the first four to six weeks following emergence to avoid yield loss.
Mississippi State University has named Dr. Jason Krutz as Extension/Research Irrigation Specialist at the Delta Research and Extension Center
Yesterday (4/30), I had a call from a consultant who found about 20% infestation of 3-4 day old SWCB in Non-Bt, V6 stage corn in the Minter City area. There were places in the field that averaged 40-50% infestation, but overall was about 20%.
Over the last several weeks corn has either passed or approached the V2-V5 stage of corn growth. During this time we have received numerous calls about corn having a yellow, streaky appearance. Many of the fields we received calls on
