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.
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.
Suggested herbicide programs in Mississippi soybean have been updated to address multiple resistance to glyphosate, ALS, and/or PPO herbicides in Palmer amaranth.
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.
This article lists grain sorghum hybrids which have demonstrated superior productivity in the MSU MAFES Grain Sorghum Hybrid Trials and neighboring University trials. This information should improve your ability to select well-adapted sorghum hybrids for Mississippi based on University performance trials.
Barnyardgrass is the most common and troublesome weed of Mississippi rice.
Black rot is on the minds of many sweetpotato producers in the United States. The fungal disease was reported in North Carolina in 2015, and there have been at least three diagnosed incidence of black rot in Mississippi since last
Extensive research has been conducted with poultry litter as a nutrient source for row crops within Mississippi. Mississippi ranks among the top five states in both numbers of broiler chickens grown and quantity of meat produced. Broiler production primarily is
