Over the last few years, interest in “yield improving” row crop planter modifications, add-ons, and technologies have been topics of discussion for growers. While there is benefit from various technologies in specific row crops, the jury is still out on every technology and new product contributing to yield (and profit) in every crop grown in […]

Scouting for Diseases, VBC
Lesions on the Leaf Late leaf spot is starting to be found in more fields this week, including those with timely and expensive fungicide programs. Switching modes of action and/or including Bravo or sulfur in with the next fungicide application, or tank mixing a systemic product with bravo (e.g., if the previous spray was bravo) […]

Grain Combine Yield Monitor Calibration
As we continue to progress through the growing season, many growers are beginning to service and set up equipment for corn harvest. This is an excellent time to check yield monitor components if you wish to collect and record yield data. The July 19th crop progress report for South Carolina estimates that 26% of the […]
Corn, Cotton, and Soybean Disease Update
In the last two weeks, most of us have received large amounts of rainfall. Daily rainfall of over 2 inches was observed in many areas and several places got 5+ inches of rain in those two weeks. In general, the rainfall was good for crops. However, it also increased our odds of getting foliar diseases […]

Fungicides, Pre-Harvest Weed Control, Stinkbugs, and Irrigation
Corn Everyone had to watch as Elsa passed over South Carolina over the last few days. Fortunately, for the most part if you were off the coast rainfall and winds stayed in the manageable levels. However, it very well may have blown spores into our state for several diseases including Southern rust on corn, soybean […]
Peanuts – Patch of Dead Peanuts, CV Pictures
More than one way to skin a cat, more than one reason a patch of peanuts can be dead in a field. Drowned in a bottom, struck by lightning, killed by disease, terminated by herbicide, and other woes… Zinc toxicity can also be fatally toxic. Aside from a soil test report indicating elevated levels, visual […]
Peanuts – Yellow in the Canopy
More rain coming in and out of the week ahead. Hurricane Elsa is estimated to approach near SC in about 5 days, with some bands possibly earlier. Making use of opportunities as we have them to maintain fungicide coverage will help all the more to put our disease management in a more secure position. Playing […]
Corn and Soybean Update – Fungicides, Irrigation, and Tassel Nitrogen
CORN Fungicides As we close in on the 4th of July, we need to consider our possible fungicide applications on corn and soybean. Weather is one of the big drivers for foliar diseases in both of these crops. The worst-case scenario is not a mid-afternoon thunderstorm which delivers 1+ inches of rain but then the […]
Peanuts – Spider Mites
Drake Perrow, crop consultant in Cameron, SC, found spider mites in peanut today. For the obvious, yes this is early, and the more obvious, yes we are dry. Good things going for us now are the relatively cooler temperatures (low-mid 80s) this week, clouds, and the decent chance of rain hopefully we will receive. Especially […]
Update – Foliar Diseases in South Carolina Corn
The majority of our corn crop is at VT or R1 and this is the appropriate time to start making the decision whether or not to spray a fungicide. Observations from South Carolina corn fields: At the Edisto REC Dr. Plumblee and I have walked several fields and the corn is very clean when it […]
Water Requirements for Activating Preemergence Herbicides
With rain visiting our state today, the topic of how much rainfall does it take is timely. Surface applied herbicides, such as Prowl or Valor, typically need a minimum amount water after application to properly “activate” in the upper soil profile. Activation means the herbicide is dissolved in the soil water solution and readily absorbed […]
Peanuts – 45 DAP Fungicides and More
Peanuts planted the last week of April are reaching 45 DAP this week. Fungicide programs for leaf spot should begin no later than 45 DAP and starting closer to 40 or 30 DAP can be warranted in fields with a history of challenging disease pressure, later plantings, volunteers nearby, and similar risk factors. If rains […]
Mid-Season POST Herbicides in Peanut
With most of the state getting an abundance (some places an over-abundance) of rain over the past week, expect weed flushes to begin in earnest. As most plantings are approaching or past the 28-to-30-day mark, there are several options for us once field conditions permit over-the-top spraying. A paraquat program in peanut either tank mixed […]
Stubby Root Nematode in Corn
I am sure that many of you are getting reports of “bad/sad” looking corn in a range of growth stages. As we all know this year’s corn crop has been through every possible type of stress. Don’t forget to look at the roots! Stubby root nematode is very common as are Columbia lance, lesion, Southern root-knot […]
Fungicides and Southern Rust in Corn
With extensive rains occurring across much of South Carolina in the last week our corn crop is getting back on track and more than half of it is in the process of tasseling. This is the growth stage where most growers will be deciding whether to spray a fungicide for foliar diseases. Here are a […]
2021 Reminder – Dicamba Spray Guidelines
As folks gear up (early planted crops may have already sprayed) for using dicamba (Engenia, Xtendimax, Tavium) in cotton and soybean, some reminders for applicators. These herbicides can only be applied by certified applicators (restricted use pesticide) that have taken the required dicamba training in 2021. The last day of permitted applications of these dicamba […]

Assessing and Response to Freeze/Frost Injured Corn
As many of you know, temperatures across the state did drop below freezing last Thursday and Friday nights. I have heard some reports of temperatures dropping to 28 F or below in specific areas that had corn planted. Since we have had 5-7 days since the freezing weather, we should now be able to assess corn stands and mortality […]
Corn Response to Cold/Freezing Temperatures
As a follow-up to my previous post on Sunday (3/28) I wanted to discuss what we can expect from the cold temperatures tonight and tomorrow regarding recently planted and young corn. The National Weather Service is now projecting the low for Blackville, SC to be 34 F, 32 F & 36 F over the next […]

If you have noticed the 7-day forecast for this week (3/28 – 4/4), our Easter cold snap is right on time. Nighttime temperatures will […]
