The 2011 Mississippi State University Row Crop Short Course was held from December 5 – 7, 2011. Topics covered during the Row Crop Short Course included insect and weed management, fertility management, agronomic aspects of crop production, and a farm
The numerous options for seed treatments can sometimes be confusing. They also change depending on what company you are buying from. Generally, they all perform well for what pests they are targeting but there are differences that you need to be aware of. Below is a link to an article Scott Stewart, The University of Tennessee, posted that breaks down most of the options very clearly.
You are invited to the 2012 Delta Ag Expo. The Delta Ag Expo provides farmers and others interested in agriculture an opportunity to see the latest technology in agricultural products, services, and information. You will have the opportunity to view agricultural exhibits and talk with extension and research personnel and get up-to-date information for planning your crop year.
I would like to thank everyone for attending the Rice Short Course. At much request, I have included copies of the presentations made at this short course. Also, I have attached a preliminary copy of the Rice Variety Trial Booklet.
On behalf of the Mississippi State University Extension Service we would like to cordially invite you to attend the 2011 Row Crop Short Course to be held at the Bost Extension Center on the campus of Mississippi State University from
Severe Cercospora blight coupled with cooler temperatures as will as a cool north wind worked to defoliate soybean plants prematurely following Tropical Storm Lee.
Since the middle of July, numerous fields have been confirmed to have cotton plants infected with the bacterium that causes bacterial blight. The majority of the cotton fields were contained within a few counties in the Delta (Bolivar, Coahoma, Leflore, Quitman, Sunflower, Tallahatchie, Washington), and a low number of exceptions outside of the Delta (Calhoun, Grenada, Monroe, Yalobusha). The organism that causes bacterial blight has the potential to overwinter on cotton stubble left standing in the field.
The information included in this blog update originated from the soybean rust telephone conference held on August 29, 2011.
Damaged grain sorghum panicles can allow many different fungi to enter and infect the developing grain or simply allow the fungus a place to reproduce if a kernel has been removed from the panicle itself. A similar situation can occur
Well, it is that time of year again. Seems over the past 5 seasons we begin to encounter foliar cotton diseases during this particular week in August. 2011 appears to be the year when the majority of these leaf spots are the worst they’ve been compared to the previous 4 seasons.
This is the time of the year when I tend to get a ton of telephone calls regarding the presence of rotten (moldy) corn ears. Over the past few weeks I’ve observed a range of symptoms on corn ears. In extreme cases the entire ear was covered with fungal growth and corn kernels were beginning to sprout but in the less severe cases only the tip was covered with fungus. Many fungi can inhabit a corn ear and in some cases the specific fungus present will depend on health of the corn plant, whether or not the ear has sustained any damage (insect or otherwise), how far the ear filled out, previous crop in the field, length of time in the field past physiological maturity, plant stress and duration of the stress during the season, and environmental conditions.
Bacterial blight (or angular leaf spot) continues to be the hot topic in cotton production even at this late stage in the season. With continued temperatures between 86 and 97°F as well as scattered rainfall throughout much of the state it is likely that bacterial blight will continue to defoliate plants and infect bolls.
Southern MS On Monday and Tuesday (August 8 & 9) the soybean disease scouting crew made a tour through southern MS to scout soybean sentinel plots as well as commercial fields and kudzu. Little if any disease was identified; however,
Currently, a trial is underway in Stoneville, MS to determine the impact of bacterial blight on the yield of some of the more commonly planted cotton varieties in MS.
Soybean scouting continues throughout MS for foliar diseases. Over the past week to ten days, aerial web blight has been identified in several fields in eastern and northeastern MS. However, aerial blight has not been identified in the Delta and seems
Over the past 7 days, numerous cotton fields have been determined to be infected with bacterial blight, caused by Xanthomonas axonopodis pv. malvacearum (formerly Xanthomonas campestris pv. malvacearum). In addition to the growing number of acres in MS having been
The soybean crop is advancing regardless of the extreme environmental conditions encountered throughout MS. At present, there are no foliar diseases of much consequence to report from either soybean sentinel plots or commercial fields. A little frogeye leaf spot has
Several fields of cotton in the Delta, as well as one field in Monroe County exhibiting symptoms of bacterial blight have been detected over the past 5 days. In addition, a significant acreage of cotton in Arkansas has been determined
Southern corn rust was detected in Coahoma County yesterday at VERY LOW LEVELS. This does NOT mean that a fungicide application is necessary especially since most corn has reached the dent stage throughout the general area. To date this has been the only southern rust detected in MS.
The incidence of foliar disease in cotton across MS have been on the rise over the past 5 years. In addition, fungicide applications have been suggested as a means of managing the leaf spots and increasing yield. Research trials conducted at MSU and elsewhere suggest that fungicides aren’t beneficial when it comes to enhancing cotton yield.
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
One of the biggest questions I receive each year has to do with whether or not a specific disease is present on soybean at a particular time. Most and I say most since this is a statement that can differ
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
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.
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
