What is An Acceptable Final Plant Population in Cotton?
This planting season has been challenging for a number of reasons. Cool, wet weather in early May gave way to very dry weather for several weeks thereafter in many areas of the state. Emergence problems have been observed in several areas
Pheromone Trap Counts, June 1, 2016
It is once again time to start posting pheromone trap results to assist you in making insect management decisions. This year we have 3-4 bollworm and 3-4 tobacco budworm pheromone traps in 5 Delta counties and 3 Northeastern Hill counties
How Long Will Residual Herbicides Remain on the Soil Surface Without an Activating Rainfall?
Spring weather has proven challenging once again in 2016. Cool, wet conditions persisted into early May with planting not really getting started on a broad scale until late in the first week of May or the beginning of the second
Spider Mites Showing up in Small Cotton in MS
Spider mites have been becoming more widespread over the last two weeks. Currently we have quite a few acres requiring treatment for spider mites and several that have already received an application. The hot dry weather we have been dealing with
When is the Best Time for the “Tassel Shot” on Corn?
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.
Rice Disease Calendar
Included in this blog post are a rice disease calendar. Information presented in the calendar deals with the most commonly observed rice diseases throughout the MS rice production area. In general, the occurrence of diseases on rice will depend on the planting date, general field history as related to previous crop, and the environmental conditions throughout the season.
UPDATED First Soybean Rust of 2016 Detected in Four Southwest MS Counties
On Tuesday, May 24, 2016, soybean rust was detected on kudzu in Amite, Pike and Wilkinson counties in southwest MS. The observations of soybean rust yesterday mark the earliest appearance of the disease by a little more than 6 weeks as compared to the past. No specific management practices are suggested at this time.
Updated Soybean Disease Calendars for MG IV and MG V Soybean
Included in this blog post are updated disease calendars for MG IV and MG V soybean to aid in scouting plant diseases. Keep in mind that several variables can impact the time of year when specific diseases are observed. Planting date, variety susceptibility, number of years a particular field has been in soybean, and prevailing environment can all play a role in when a disease is observed.
Thrips Pressure Starting off Heavy in MS Cotton
Calls about thrips treatments in seedling cotton have been picking up substantially this week. As ryegrass and other ditchbank hosts begin to dry down, thrips numbers will likely increase in the next couple weeks. The 100% chance of rain today (5/20) now
When Should we Start Irrigating our Corn?
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.
Plant Stand Effects on Peanut Yield
This planting season has been pretty good to peanut growers overall. While rainfall has been sporadic across the state, most of us have had several long, dry windows to get peanuts planted since about April 25. Having said that, there
Thrips in Peanut: When to Spray
There are questions every year about spraying thrips in peanut. In general, we have recommended using an at-planting insecticide to manage thrips and that is adequate in most situations. However, we did a study two years ago where we sprayed peanuts
Comment Period is Open for Transform Section 18
In March, the Mississippi Bureau of Plant Industries and other states in the Mid-South submitted Emergency Exemption (Section 18) requests to use Transform for tarnished plant bug control in cotton. The reason for this request is that the original registration
How to get the Best Return on your Corn Nitrogen Dollars
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.
Rice Seed Treatments and Cool Wet Soil Conditions
Every year we have a point in the planting season where we start getting questions about how heavy rainfall and cool temperatures affect seed treatments in rice. The one thing to remember is that the clock starts ticking on the
Cutworms Showing Up in Mississippi Crops
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
Why Can’t I Use Propiconazole on Peanuts this Year? A story of MRL’s and International Markets
Alan Henn1 with contributions by Michelle Samuel-Foo2 1Extension Plant Pathologist, Mississippi State University 2 Regional Coordinator, IR-4 Southern Region, University of Florida. mfoo@ufl.edu or 352-294-3991 Most peanut growers have received notification from their buying points not to use any fungicides
Wheat Disease Update: April 16, 2016
Increased observations of foliar wheat diseases have occurred over the past two weeks. Leaf rust, stripe rust and Septoria leaf blotch have been commonly observed throughout the state. In addition, with the current environmental conditions (humidity, rainfall) and the general growth stages observed, the potential for Fusarium head blight (scab) may be similar to as occurred during the 2015 season.
Wheat Disease Calendar
Scouting for wheat diseases is most important once the flag leaf emerges. However, foliar diseases can occur throughout the growing season. In some cases wheat diseases differ by season based on inoculum pressure as well as environment.
Updated Corn Disease Calendar
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.
When does Corn Yield Potential begin to Suffer from Late Planting?
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.
Barnyardgrass Management in the Mississippi Delta
Barnyardgrass that is allowed to survive and produce seed in soybean can cripple a rice weed control program the following year.
Wheat Disease Update: March 25, 2016
Wheat diseases have been few and far between this winter. Little wheat was planted in the fall of 2015. However, in some key areas, rust diseases (leaf and stripe) as well as bacterial leaf streak have been observed on wheat.
Managing PPO-resistant Palmer Amaranth in Mississippi Soybean
Suggested herbicide programs in Mississippi soybean have been updated to address multiple resistance to glyphosate, ALS, and/or PPO herbicides in Palmer amaranth.
