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
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.
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.
As we traveled through Tunica county today we noticed a few growers received a shower or two recently. Elsewhere across the Delta, a shower would be a welcomed Memorial Day event. Over the last couple of days we have received
In 2014, the Irrigation Team added surge valves to our list of tools to increase irrigation application efficiency. When using a surge valve, water is applied in a series of on-off cycles alternating between two irrigation sets. By utilizing surge
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.
Utilizing moisture sensors to trigger an irrigation event is one method to increase irrigation efficiency. Using the “calendar” or the “neighbor” method of determining when to trigger an irrigation event is not the most efficient method. Soil moisture sensors are
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.
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
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.
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
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
To address the declining Mississippi River Valley Alluvial aquifer, Mississippi State University developed the Row-Crop Irrigation Science and Extension Research (RISER) program. RISER’s goal is to develop a science based approach for evaluating Irrigation Water Management (IWM) practices in the Mississippi Delta and
Rain is in the forecast for tonight. As of today only a few growers have initiated corn irrigation, mostly to incorporate fertilizer after missing the last rain opportunity. Elsewhere, growers are beginning to prepare for that first irrigation event. Poly-pipe
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
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.
The most recent NASS survey says that as of May 1, 48% of soybean acres had been planted, which is well ahead of both Louisiana (36%) and Arkansas (24%). Given the wet weather we had over the weekend and yesterday,
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
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

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.
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.
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.
Barnyardgrass that is allowed to survive and produce seed in soybean can cripple a rice weed control program the following year.
