Stink bugs damage small corn by feeding through the whorl or side of the stem hitting the growing point which either causes “dead heart†or severely stunts the plant. Severely stunted plants may not die but essentially become a weed. In many cases, corn that has been fed on without hitting the growing point will recover. Even if the growing point is not hit, in some situations where stink bugs feed through the stem you will see irregular growth.
During 2012 fungicide application trials were conducted at a field site west of Greenwood, MS. Following a major wind event that occurred early in June, excessive greensnap was observed in plots that had received V6 foliar fungicide applications. Plots were assessed to determine if fungicides could consistently alleviate the occurrence of greensnap compared to untreated plots.
Oftentimes, deciding whether or not to make a fungicide application to corn in vegetative growth stages is not based on disease. Rarely are foliar diseases an issue in vegetative growth stages (save for extremely rare situations). More often than not, the decision to apply a fungicide at a vegetative timing is based on the theory of “plant health”, or physiological enhancements to the plant as a result of the fungicide that have been difficult to replicate in all situations.
Unrelenting rainfall continues to delay much field-related progress. This article gives suggestions for making corn replant decisions and keeping up with crop needs, such as nitrogen fertilizer application.
Historically, we have chased the planter with the sprayer to apply residual herbicides. This presents several potential problems…
Use the information contained in this blog post to aid in determining the specific disease in field corn. Scouting corn for the presence of disease is difficult and can be confusing since some foliar diseases appear similar to one another such as gray leaf spot and southern corn leaf blight. In addition, particular diseases are more important depending on the particular growth stage when they are encountered.
According to the National Agricultural Statistics Service in Mississippi, there were 2.7 days suitable for fieldwork for the week ending Sunday, April 14, 2013. Dry conditions during the first half of the week allowed for some fieldwork to be done. Wet conditions in the last half of the week slowed or stopped all fieldwork. Soil moisture was rated 40 percent adequate, and 60 percent surplus.
Soybeans U.S. ending stocks for soybeans remained unchanged in the April World Agricultural Supply and Demand Estimates (WASDE) report at 125 million bushels. Analysts were expecting the ending stocks number to be 137 million bushels, with a range from 107 to 160
This is an important question right now with the weather conditions that we have had over the last few weeks. A considerable amount of corn and a little bit of rice has been planted over the last 3 to 4 weeks. In most of those fields, the crop has either just emerged or has not emerged yet.
As rains continue to delay corn planting progress, more concerns are rising regarding the appropriate “cut-off†date for planting corn. Recent MSU research gives a solid basis for addressing this question.
USDA released their annual Prospective Plantings report and quarterly Grain Stocks reports today (Mar 28). The acreage report was largely in-line with pre-report expectations, but the stocks report had quite a shock for corn supplies and a slight surprise for
— The following is from Dr. Brian Williams — Nearby May wheat futures closed up a penny Friday to close the week at $7.29/bu. May corn finished down 6 cents at 7.26, but corn did finished up on the week.
Throughout the season many ag-related professionals ask questions about particular fungicides. More specifically, sometimes it can be confusing to determine if a particular product falls in the strobilurin class of fungicides or the triazole class of fungicides. The current update includes information to help determine the particular class of fungicides for strobilurin, triazole, and pre-mix products using fungicides labeled for application in soybean as an example.
Fall-applied residual herbicides went out on a significant amount of acreage in Mississippi during the fall of 2012. In some cases, such as where glyphosate-resistant Italian ryegrass is present, these applications are key components for optimizing weed control. However, in
You must provide numerous resources and management to optimize the opportunity for corn plants to produce high yields. Of course, favorable weather plays a huge role as well. This article describes areas where we can improve corn yield potential.
March is here, expectations are high and our fields may dry out soon, if rain holds off. So when should we start planting corn? This article gives tangible recommendations for determining suitable planting time when nature throws us curveballs.
Sugarcane beetles (Euetheola humilis rugiceps), have caused many Mississippi corn producers major headaches in the last decade. Ironically enough, most of the problem areas are in the Hill region of the state and not the Delta region. Sugarcane beetles are certainly present in the Delta but rarely cause widespread problems in corn (to date). Sugarcane beetle infestations are sporadic in nature but heavy infestations can be very serious and require replanting in some situations. Unfortunately there are no viable rescue treatments available, so this pest has to be managed at planting.
If you need some help deterring blackbirds or other ground-feeding birds from ruining your corn stand, you can make plans now regarding the product Avipel.
University Research and Extension Entomologists from across the southern U.S. participated in a survey where they rate the performance of insecticides against various insect pests in cotton, soybean, and field corn.
On February 7th 2013, Mississippi State University hosted the first annual “Future of Agriculture Graduate Student Competitionâ€. The goals of this event were to provide students an opportunity to present their research findings to a diverse audience that included growers, consultants and industry personnel and interact with people from different segments of the agricultural community.
On February 7th 2013, Mississippi State University will host the first annual “Future of Agriculture Graduate Student Competitionâ€. The competition will be open to M.S. and PhD. level graduate students that are working in production agriculture.
The 40th Annual Delta Ag Expo will be held January 16-17, 2013 at the Bolivar County Exposition Center in Cleveland, MS. There will be several Mississippi State University Researchers and Extension Specialist’s on hand to answer any questions you may
The MSU Corn Hybrid Demonstration Program evaluates superior corn hybrids from numerous seed companies who participate in the MSU Corn for Grain Hybrid Trials. Our objective is to provide you more opportunity to evaluate premier corn hybrids and substantially supplement the information gathered in the University Hybrid Trials.
by: Brian Williams and John Michael Riley Estimated U.S. production and acreage for corn, soybeans, and wheat in the December USDA report remain unchanged over the November estimates. U.S. soybean yields for 2012 are estimated at 39.3 bushels/acre, down from 2011
Prickly lettuce plants are mostly covered in spines along the leaf margins and on the underside of the leaf midvein.
