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
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.
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.
Frustration is probably the most predominant emotion in the Mississippi Delta. I looked through our notes this morning and estimate that since March 14, we have had less than 10 plantable days. That may be stretching it because there have
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.
The USDA Crop Progress & Condition Report stated 1% of the Mississippi rice crop had been planted as of April 7. Last year, 33% of the crop had been planted and we have averaged 12% over the last five years.
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.
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.
