Corn reproductive stages generally comprise nearly 60 days for corn hybrids grown in Mississippi at normal planting dates. Identification of these stages is critical for making prudent management decisions and anticipating crop response to practices and environmental conditions.
Southwestern corn borer trap counts were up this week in Coahoma county. As a reminder, our threshold for foliar sprays on non-Bt corn is to spray one week after trap counts exceed 100 per trap from tassel to full dent.
Every few years we have a surge of potato leafhopper calls in soybean in MS. This is one of those years. Potato leafhoppers strongly prefer smooth leaf soybean varieties and I suspect that the calls increase on years where popular
Over the past week the corn disease situation in MS has changed. Several foliar diseases are starting to be observed in our production system. However, the vast majority of the leaf spots present are not yield-limiting issues.
So far, the 2018 cotton crop is off to a good start. Good growing conditions caused cotton to grow off from thrips pretty quick and plant bugs have been fairly light so far this year. A lot of cotton has
This article is dated but applies very well today given the pop up showers across most of the state lately. Every year when afternoon thunderstorms start popping up, the phone starts ringing about rainfastness. Rainfastness simply means the amount of
Numerous questions over the past several weeks regarding automatic foliar fungicides applications in soybean have been made. The current blog post should help guide decision-making regarding the R3/R4 automatic fungicide timing.
Numerous questions have came in over the past 7-10 days regarding managing cotton growth with plant growth regulators. While every situation can be unique with respect to cotton growth and development and subsequent plant growth regulator use, the slides given
We have been trapping southwestern corn borer for the last few weeks, but most traps have not caught any moths until this week. Overall, numbers are still low, but are starting to increase which may signal the beginning of the
This is a recycled article from 2012 and slightly updated but it fits well with recent calls. Sentences in italics have been added or updated since original posting. We have some of the earliest beans that are R3/R4 getting fungicide applications
As the Mississippi corn crop approaches tassel stage, weather has fluctuated from dry to rainy conditions during recent weeks. Thus, how may this affect how the corn will respond to mid-season application of various management inputs, including nitrogen fertilizer or other products? This article will discuss factors that could dramatically affect corn response.
Soybean root diseases have started to be observed in the Delta. Over the past week several calls have been received regarding the presence of southern blight. Dead seedlings along with white mycelial growth below the soil line is a common observation in fields where southern blight occurs.
Mississippi State University will be hosting 2 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.
In 2017, we were able to accurately predict the threat of RBSB based on sampling ditch banks in the spring. Every year we sample ditch banks across the state to make collections of various insect pests. With most pests, such
This article lists grain sorghum hybrids which have produced superior yields in the Mississippi Grain Sorghum Hybrid Trials and neighboring University trials. This information should improve your ability to select well-adapted sorghum hybrids for Mississippi based on independent performance testing.
Over the years many have questioned whether the use of a seed treatment is considered IPM because they are used prior to the onset of a problem. In our area, and across most of the cotton belt, thrips are considered
As the 2018 cotton season approaches, it is a good time to look back at 2017. From an insect management standpoint, the number one thing that stands out about last year is the amount of foliar sprays that were made
In 2017, we were able to accurately predict the threat of RBSB based on sampling ditch banks in the spring. Every year we sample ditch banks across the state to make collections of various insect pests. With most pests, such
I have recently received a few call about slugs in corn. I suspect this will increase in more crops as planting continues and they begin to emerge. Slug problems usually start on corn first, then move to soybeans, then cotton in our area.
The MSU MG V OVT soybean locations were evaluated for disease during the 2017 season. Multiple diseases were rated at multiple locations and are provided in this post by herbicide trait. Cercospora blight, Septoria brown spot and target spot were the three most commonly encountered diseases during the season.

Over the last few weeks we have made an attempt to explain the data we have concerning furrow irrigated rice. The first installment explored the small plot research conducted by Lee Atwill, MSU Graduate student. Small Plot The second installment tried
Data from “on farm” trials are helping MSU Researchers understand some of the yield perimeters associated with furrow irrigated rice. If you ask experienced furrow irrigated rice producers one thing is clear, they recognize only a small, if any, yield
Producing rice in a “rowed-up” manner as other row crops such as corn, soybean, and cotton was a foreign concept just a couple of years ago. Row rice or furrow irrigated rice was initially investigated by MSU Researchers as an
