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.
Where Palmer amaranth has emerged, it is imperative to make a timely application of a postemergence herbicide.
Over the past week we’ve received two reports of frogeye leaf spot in reproductive soybeans. In both cases, a susceptible variety was planted and frogeye leaf spot symptoms can be clearly distinguished throughout the canopy. Following the observation and reports of strobilurin-resistant frogeye leaf spot in two fields in MS last year, and from adjacent states, it is most important to determine what particular soybean variety is planted in a field prior to making a decision on a specific fungicide product for yield loss prevention.
In general, rice planting is nearly completed and most rice planted before early May is going to flood. According to USDA’s Crop Progress Report, growers in Mississippi had planted 72% of the expected acreage by Sunday, May 26. Other than
A good deal of progress was made this past week with respect to getting the 2013 cotton crop planted. Rainfall during the middle part of last week put planting activities on hold until Friday afternoon (of last week) or Saturday
No doubt this is a very late planted crop by Mississippi standards, so I was a little surprised when numerous thrips calls started coming in about a week or so ago. Usually thrips issues are much worse on cotton that is growing off slow due to cold weather or any number of issues that may slow growth.
Several people have asked about a list of fungicides and the specific diseases they may manage best. Included in this post is a table that has been put together by the Corn Disease Working Group of fungicides and how they respond in environments with specific diseases in efficacy trials from throughout the U.S.
According to the USDA National Agricultural Statistics Service in Mississippi, 46% of the soybean acreage was planted as of the week ending May 26, 2013. At this time, 32% of the crop is emerged. Several areas around the state received
Limited progress was made with respect to cotton planting in Mississippi during this past week. As has been the case for the past several weeks, field conditions permitted progress to be made for a short period of time before the
With all of the rainfall that we have had around most of the state, there have been a lot of questions about the impact on seed treatments. In general, most of the seed treatments that are being used in all crops are water soluble. Typical levels of rainfall should not have a negative impact on the efficacy of seed treatments, but excessive rainfall may.
Several common diseases have been observed in the MS corn crop over the past week. Common rust and northern corn leaf blight are typical diseases in corn and are likely the result this early in the season due to the cooler than normal temperatures and ample rainfall we’ve received over the past month. But, with the generally atypical environment we’ve experienced this season the likelihood of more non-typical foliar diseases occurring is potentially increased. Proper diagnosis prior to a management decision is therefore increasingly important.
