Numerous fungicide trials were conducted during 2015 to determine the efficacy of fungicides on frogeye leaf spot. Included in this post are the majority of the soybean fungicide trials conducted at R2, R3, and R5 in Stoneville, MS on a FLS-susceptible soybean variety. A total 39 different product or product combinations were evaluated. A summary table is included to highlight a specific product and the trials that particular product was included in.
The entries contained in the MSU soybean OVT were screened for their sensitivity to the root-knot nematode during 2015. Contained within this blog post are the root galling responses of 133 entries as well as the yield from the RKN infested location.
Soybean diseases continue to be observed throughout the MS soybean production system. Over the past several weeks calls have centered on Septoria brown spot, Southern blight, and some limited questions regarding soybean rust.
Numerous questions over the past few weeks regarding fungicide product selection for the R3/R4 soybean application timing. Specific comments regarding the efficacy of products on frogeye leaf spot will be presented in an additional blog post. In this post, comments regarding application volume, fungicide application rates and decision on specific products.
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
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
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.
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.
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.
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
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

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.
Observing the preplant intervals for 2,4-D and dicamba prior to planting is important.
We posted an article last spring about utilizing several best management practices in an overall IPM program to manage tarnished plant bug in cotton. We included a pdf that highlights all of the research we have conducted over the last
Find below the Final version of the 2015 On-Farm Rice Variety Trial. During 2015, small plot rice variety trials were conducted near the following locations; Choctaw, Clarksdale, Hollandale, Ruleville, Shaw, Stoneville, and Tunica. Variety trial data is presented segmented by
The entries contained in the MSU soybean OVT were screened for their sensitivity to the root-knot nematode during 2014 (and again in 2015 – data forthcoming). Contained within this blog post are the root galling responses of 142 entries as well as the yield from the RKN infested location.
Preliminary results indicate that Palmer amaranth resistant to PPO herbicides is likely in Mississippi
The results of the 2015 MSU-ES Soybean Variety Demonstration Program have been updated to include disease ratings for Cercospora blight, frogeye leaf spot, Septoria brown spot, and Target spot. These evaluations were collected at many locations in 2015 by Dr.
Variety selection is one of the most critical management decisions associated with soybean production. Factors such as soil type, planting date, irrigation capabilities, row spacing, harvest capacity, and others may influence the decision of selecting an appropriate variety for profitable
