As the corn crop nears maturity, knowing when you can safely terminate irrigation timing, while optimizing yield potential is likely the most important decision you will face. In order to make this call, you need to estimate when the crop will reach maturity and how much moisture is present in your soil. This article outlines the steps needed to help make this process accurate and reliable.
Controlling GR Palmer amaranth on turnrows and ditchbanks has become a critical component to weed control.
Southwestern corn borer trap counts remained very high in some areas this week. The highest counts reported were in Sunflower, Quitman, and Coahoma counties.
The corn disease season continues to be somewhat quiet. Few if any foliar diseases have been observed throughout MS. Southern rust continues to be observed in western and southern MS; however, the disease has only be observed at low levels (one to two leaves) in all situations to date.
The North Mississippi Research and Extension Center Field Day is scheduled for August 11, 2016 from 8 am to 1:30 pm with lunch provided.
Southwestern corn borer trap catches appear to be peaking this week. Several counties had individual traps with numbers at or near the current threshold and a couple well above threshold. As a reminder, the current threshold is 50 per trap
Southwestern corn borer numbers increased significantly in some areas this week. The highest numbers were 377 caught in Leflore County and 450 caught in Coahoma County. The current threshold in the 2016 Insect Control Guide suggests spraying when 50 moths are caught
Much of the corn has reached the reproductive stages, while some is still in the vegetative stages. Several caterpillars, including fall armyworm and corn earworm, can infest corn, especially non-Bt corn, during both stages of development.
To date, disease issues in the MS corn crop have remained somewhat quiet. Common rust has been the most prevalent disease as a result of wetter and cooler temperatures until the past 7 to 10 days. As of this morning (6/18/2016), southern rust has not been detected in MS.
Overall, southwestern corn borer traps remained low throughout the state. However, one trap in Leflore county captured 178 moths over a 7 day period. Although they do not appear to be widespread, this indicates that there may be pockets with
All southwestern corn borer trapping locations did not report this week, but numbers were very low across the state. The highest numbers were in the south Delta, but still well below threshold with the highest number being 22 in one trap
As much of our corn crop reaches tassel stage, it is apparent some fields are noticeably shorter than normal. This article will discuss what caused the corn to be short and whether or not it may reduce yield potential?
Many corn growers are implementing different “tassel shot” inputs as part of their management program. Questions often arise regarding how critical the application timing is, especially when weather or other issues may complicate timing of such inputs. This article discusses situations when application timing may be very important, as well as those when precise timing is not critical.
The recent stretch of dry weather has prompted much concern about the proper time to initiate irrigation for corn. We have considerable resources and information available to help answer this question and improve our corn productivity and profitability by implementing new strategies designed to address the crop needs.
Your crop response to nitrogen fertilizer may vary considerably since our environment is very conducive to nitrogen loss. This article describes methods to optimize corn yield response to nitrogen fertilizer application.
We have had several calls over the last week about cutworms reducing plant densities in cotton, soybean, and non-Bt corn. Based on the number of calls, it appears that cutworm populations are much higher than they have been the last several
Included in the current blog post is an updated disease scouting calendar. The timing of observations of some of the diseases included has been changed and some additional diseases that continued to be observed throughout the MS corn production system are included. Be mindful that foliar corn diseases can be observed throughout the entire season. Scouting for disease should begin shortly after emergence especially given that seed and seedling-associated diseases can impact corn stand as well as replant decisions in severe situations.
Much like the last three years, as rains delay corn planting progress, concerns arise regarding whether you will have ample opportunity to plant your corn crop in a suitable time window. This article states yield expectations and new guidelines for late corn plantings based upon MSU research.
Mississippi State University will be hosting 5 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, and herbicide symptomology.
Observing the preplant intervals for 2,4-D and dicamba prior to planting is important.
The preplant interval for clethodim application before planting a grass crop (corn, rice, grain sorghum) is real and should be strictly observed.
Mid-South Farm and Gin Show convenes in Memphis February 26 If you didn’t get a new tractor, combine or other piece of machinery for Christmas, the perfect opportunity to see the latest models is right around the corner. The 64th
The venue is the Cook Convention Center, Memphis. All available footage is taken, every inch of the Convention Center, as well as the sidewalk outside the Center on Main Street in Memphis, is filled with exhibits, machinery, equipment, and products
The Corn Hybrid Demonstration Program provides us first-hand opportunity and information to better assess hybrid performance and adaptability in Mississippi. This program provides unique opportunity to observe and evaluate plant characteristics and environmental responses of our best corn hybrids in local, on-farm demonstration plots. This is a complete summary of 2015 results.
