Wheat Disease Update: May 4, 2013
Scattered reports of wheat diseases have been made over the past two weeks. Limited leaf rust, stripe rust, and Septoria leaf blotch can be observed in some wheat fields. In addition, in some situations bacterial leaf streak can be readily observed on flag leaves in some limited situations. In some cases, bacterial leaf streak and Septoria leaf blotch can appear similar to one another. In most cases, Septoria leaf blotch can be observed in the lower canopy and likely will not move up the plant to the flag leaf. However, bacterial leaf streak can be more readily observed on flag leaves in some fields.
Stink Bug Numbers Increasing in Heading Wheat
I am starting to get numerous calls about stink bugs in heading wheat. It is not uncommon to find stink bugs in wheat after head emergence. However, it takes extremely high numbers to cause economic damage to heading wheat. With this
Brown Stink Bugs Showing Up In Small Corn
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.
Are Early, Vegetative Fungicide Applications Beneficial for Enhanced Corn Production? (Part II: Impact of Fungicide on Greensnap)
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.
Are Early, Vegetative Fungicide Applications Beneficial for Enhanced Corn Production? (Part I: Yield)
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.
Corn Replanting Guidelines and Management Issues with Wet Weather
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.
Chase the Sprayer with the Planter
Historically, we have chased the planter with the sprayer to apply residual herbicides. This presents several potential problems…
Corn Disease Calendar
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.
Wheat Disease Update: April 20, 2013
Wheat disease continue to be discussed throughout MS. Generally speaking, stripe rust has not been near the widespread threat this season as it was during the 2012 wheat crop. Scout wheat fields for the presence of diseased and relate this to the specific variety in each field when determining particular management alternatives. Keep in mind, the general cut off date for fungicides is Feekes 10.5.1.
USDA Crop Progress and Condition Report for Mississippi
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.
April Supply and Demand Report Recap
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
Will cold and rainy weather impact seed treatments in corn and rice?
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.
What is the Cut-off Date for Planting Corn?
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.
IMPORTANT NOTICE: Tebuconazole Label Restrictions in Wheat
Please see the attached information regarding the use of products that contain tebuconazole to manage wheat diseases. Note that the label restricts the overall amount of tebuconazole that can be applied to wheat in any one season to 4 fl oz/A.
Wheat Disease Update: March 30, 2013
Stripe rust continues to be observed throughout scattered fields in the Delta. In addition, leaf rust was confirmed in isolated cases over the past week. Keep in mind that not all fields will require a fungicide application to prevent yield loss. Scout wheat fields at this time for stripe rust hot spots (small in size = less than 3 feet in diameter; to large in size = several trucks) and determine the wheat variety present before deciding on a fungicide application.
Soybean Disease Monitoring: Soybean Sentinel Plot Update and 2013 Soybean Rust Fungicide List
As we move towards the soybean season we’ve included some information regarding the labeled fungicides for application to prevent yield loss as a result of soybean rust. Soybean rust was able to overwinter in several Gulf Coast states (AL, FL, LA). However, at present, soybean rust has not been detected on kudzu in MS.
Prospective Plantings and Grain Stocks
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
Wheat Disease Update: March 23, 2013
Additional stripe rust has been detected throughout the MS Delta over the past two weeks. Scout fields for the presence of stripe rust to determine the extent of the infection in the wheat production area. Keep in mind that stripe rust will appear different on younger wheat plants still in the early vegetative stages than it does on more mature wheat plants.
Small Grains Market Report
— 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.
The Fungicides
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 Residual Herbicides: A Double Edged Sword
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
Top Ten Keys to High Corn Yields
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.
Insecticide Seed Treatments in Soybeans
What is the importance of a neonicotinoid insecticide seed treatment in soybeans? Basically it is a risk management tool. Soybean seedlings have a tremendous amount of vigor and can tolerate a substantial amount of insect injury. However, early planted soybeans can encounter less than optimal environmental conditions which can stress plants and reduce vigor. Insect injury under these conditions is an additional stress. During 2010, it is estimated that the use of insecticide seed treatments in soybeans resulted in a value of $28.8 million to Mississippi soybean growers.
