Extremely low levels of southern corn rust were observed in a single corn field in Humphreys County on Tuesday afternoon. Southern rust can be a devastating disease if left unchecked and when conducive conditions prevail (hot, humid environment).
Over the past two weeks soybean diseases have become apparent throughout the MS soybean production system. Isolated reports of frogeye leaf spot in reproductive maturity soybean fields as well as Fusarium wilt have been on the rise. Stay tuned to the Mississippi Crop Situation Blog for disease monitoring situations, including maps of counties where soybean rust and strobilurin-resistant frogeye have been made throughout the 2013 season.
Generally the 4th of July means blooms have begun to appear in many cotton fields. However, give the late start to 2013, blooms will likely not be observed on a widespread basis for another one to three weeks. Blooms have
This season’s corn crop is generally much later than normal and far behind the pace of last year’s crop. Thus, even the earliest fields will need additional irrigation or rainfall for several more weeks. This article discusses crop progress and methods to schedule and terminate irrigation water for corn.
With the dry weather we have had recently, spider mites are starting to show up in a lot of cotton fields. Spider mites can be one of the most difficult pests to manage in cotton for several reasons.
Many of the soybeans are now reaching R3-R4 growth stage so fungicides are commonly being applied. I have received quite a few calls questioning whether or not to add an insecticide in the tank since a trip was being made
In the last 7 days we have received a number of calls about adult plant bugs beginning to move into squaring cotton. In many cases, fields that were treated last week have higher or equal numbers this week. As we
Southwestern corn borer traps picking up in several areas in state.
The Mississippi State University Extension Service in cooperation with Monsanto Company will host a pigweed field day near Robinsonville, MS on July 17, 2013. The field day location is just north of Tunica National Golf Course. A more detailed map
I know it is a little early in the year, and very little if any rice is heading at this time. However, it is not too early to start thinking about rice stink bugs.
Favorable weather conditions continue to help this crop progress. Major problems outside of drift have been few for most of the spring; however, a few different issues have come up this week. Dr. Jeff Gore was called to help address a
Corn diseases continue to be a hot topic throughout the MS corn production area. Most field calls have been regarding common rust as well as northern corn leaf blight. However, over the past two weeks numerous calls regarding nutrient and irrigation stresses have been answered that were initially thought to be disease. In addition, with the recent information from Louisiana regarding the observation of Goss’s wilt in LA (a rare event in their production system) agriculturists should know that disease as well as crop stresses can be initially misdiagnosed as diseases that are not normally present in our production system such as Goss’s wilt.
At this point of the season, we still have some acres of soybean yet to be planted. The majority of those acres will be double cropped soybean behind harvested wheat. Given the environmental conditions that we typically expect during this
As of the week ending June 16th, USDA reported that Mississippi was 100% planted and 99% emerged. The later planted rice is progressing rapidly which is good. As we are experiencing more seasonal temperatures, rice will continue to progress rapidly. In
Last week consultant Brian Boyd, found the first incidence of Kudzu bugs in soybeans in the state of Mississippi in Warren County. Numbers were low, but they were definitely present. Mississippi is now up to 10 counties with positive finds,
For all intensive purposes cotton planting has been completed in Mississippi for 2013. In my estimation the majority of the 2013 crop is two to four weeks behind normal. The youngest cotton in the state is at 1 to 2
Automatic foliar fungicide applications are still widely discussed. However, data from university-based programs suggests waiting for foliar diseases that could ultimately reduce yield before making a foliar fungicide application is more economically advantageous.
The United States Department of Agriculture along with the World Ag Outlook Board released their monthly World Agriculutral Supply and Demand Estimates (WASDE) report June 12 around lunch. The report is the second to provide insight on USDA’s projections for the 2013
Monday’s crop progress had corn planting at 95% complete, just 3% behind the 5-year average. Soybeans are still behind schedule with planting progress currently at 71% for the U.S. crop and 88% for the Mississippi crop. That compares to 5
I have had 10-15 calls recently on green and southern green stink bugs in beans that are either vegetative or at R1-R2 stage with no pods. Numbers have ranged from 4-5 to 8-11 per 25 sweeps depending on the field. It is not uncommon to have a field or two on occasion to have threshold numbers of stink bugs before soybeans put on pods, but the number of fields this year being reported is certainly unusual.
Numerous reports of urea injury producing symptoms similar to northern corn leaf blight have been made over the past several weeks. Determining the difference between the two issues on a corn leaf can be difficult. Numerous photos as well as a comparison table of the differences between the two issues are included in the post.
Northern corn leaf blight and common rust continue to be identified in corn fields throughout the south Delta. Determining the specific corn hybrids planted in each field is an important first step every season. For the most part, save for a couple of fields, NCLB has still been detected at extremely low levels (= 1 lesion per leaf per plant).
Monday’s crop progress had corn planting at 91% complete, just 4% behind the 5-year average. Soybeans are still behind schedule with planting progress currently at 57% for the U.S. crop and 74% for the Mississippi crop. That compares to 5
More and more growers are applying various management inputs around tassel stage in order to improve efficiency and corn productivity. This article discusses how crop physiology affects the potential yield response and appropriate timing.
