Now is a great time to pull nematode samples if you have not already done so. Whether you pull samples regularly or have never pulled a sample, the SC Corn, Soybean, and Cotton Boards, in collaboration with Clemson University, are providing the analysis of nematode samples for free again in 2026. Knowing which nematode species […]

As many of you know, temperatures across the state did drop below freezing last night (3/16) and will again tonight (3/17). I have not heard any reports of temperatures dropping to 28 F or below yet, but Northern SC could very well have seen those temps. If you think your area experienced sub-freezing temperatures and […]

Plant 2026 is officially underway. Some farmers have already begun planting corn, while others are waiting until later dates to hedge against cold or frost. This is very much a risk/reward scenario, where we typically see higher yields from early planting, though this corn is more vulnerable to a late freeze or frost. No year […]

In February of 2026, Clemson Extension will host several county-level production meetings focusing on corn and soybeans around South Carolina. Below is a list of days and locations of the meetings. Please add the local meeting to your calendar and we hope to see you in February! These production meetings are being sponsored by the […]

In February of 2026, we plan to host several county-level production meetings focusing on corn and soybeans around South Carolina. Our list is still being modified, but below is a list of days and locations of the meetings that have been scheduled so far. A follow-up announcement for each meeting with further details will be […]

From Dr. Bhupinder Farmaha: South Carolina Farmers: Your Input Needed! I’m planning 2026 soil fertility research and extension programming across South Carolina. What are your biggest challenges with crop nutrition, cover crops, manure management, and soil health? Your feedback will directly shape our: Please take 5 minutes to complete this survey: https://clemson.ca1.qualtrics.com/jfe/form/SV_0d4i9uYaI73sM1E Let’s work together to […]

Each year we conduct multiple irrigated and non-irrigated corn hybrid trials across South Carolina to evaluate hybrid performance, working with seed companies to demonstrate hybrid performance of germplasm that is being sold commercially. In this non-bias, cross-company trial, you will find data that can help make seed ordering decisions for 2026. I encourage farmers to […]

To date, no soybean rust has been found in South Carolina. Regular samplings are being conducted across the state by agronomic agents, led by Jonathan Croft and funded by the SC Soybean Board. Jonathan sends out updates regularly through email with updates if rust is found, contact him if you wish to be on that […]

With corn harvest now in full swing across the state, we have been getting a few calls regarding grain moisture and putting grain in the bin at a safe moisture level. Generally, we like to see corn harvested at higher moisture contents to reduce in-field losses and combine losses (18-20%) compared to dry corn (15.5% […]

There has been a lot of interest in SC over the past few years in double-cropping soybeans behind corn. The main question that I hear is, “What is the last day I can plant soybeans and make a crop?” Since 2022, we have been researching this system with the hope of helping answer some of […]

With corn harvest starting up last week, now is a great time to take a few minutes to perform a yield monitor calibration. Relative and/or accurate yield data can be useful for hybrid evaluation on your farm, identifying problem spots such as nematode areas for sampling later this fall and helping make management decisions for […]

The majority of the soybean crop, planted early or late, is beginning to bloom or is now setting pods. This is the appropriate time in the growing season for growers to make a decision on spraying a fungicide on soybeans.  The common questions are when to spray, what to spray, and whether it will be […]

Corn harvest is beginning in the coastal plain as of this week. A reminder that following harvest is a great time to pull fall nematode samples to use in combination with our fall threshold values to know how to manage the crop in 2026. We are providing nematode samples for free courtesy of the SC […]

On July 29, 2025, the Clemson Agribusiness team is leading a “90-day market outlook discussions for corn and soybeans” at two locations: 9:00 am Hutto Brothers Farm — 444 Shuler Belt Road, Holly Hill, SC 6:30 pm Brogdon Family Farms – 3555 Old Manning Rd, Manning, SC Discussion Topics Include: This would be a good […]

Due to the favorable weather conditions we had in March of this year, the majority of our corn crop was planted “earlier” than in the past several years. Along with the earlier planting dates, favorable growing conditions and heat, some fields are approaching physiological maturity and beginning dry down. When corn reaches the R6 reproductive […]

Fungicides with 2,4-DB Where compatible, combining different products in a single application saves time and fuel spent going across a field. While that much is itself apparent, we also know not everything can be mixed physically or functionally without gumming up/coagulating or causing reduced application efficacy. It is not uncommon for 2,4-DB to be applied […]

With erratic rainfall this summer, our soybean planting window has been extended into July in places across the state, especially if following small grain. Over the last three years, Clemson has conducted several research trials evaluating ultra-late planted soybeans, double-cropped behind corn. I have compiled a table below that highlights some of the research findings […]

Coming into July, much of the crop ranges in age from about close to a month old to 50 to 70 days old. More than a third of the crop is pegging. After having some drier weather, an increased likelihood of rain is coming back into the forecast through the weekend and into the week ahead.  […]

Soybean bloom (R1-R2 growth stages) marks a critical transition from vegetative to reproductive growth, requiring careful management to maximize yield potential. In South Carolina’s hot and often humid climate, timely decisions during and after bloom significantly impact pod set, seed fill, and final yield. As of now (7/2), the majority of our soybean crop is […]

Below is a figure that describes the various corn growth stages during reproductive growth (from silking to black layer). The estimated number of days between growth stages will help give corn producers an idea of the progression of the crop for management decisions, specifically irrigation termination. 🌽 Reproductive (R) Stages Additional information on growth staging […]

As we move into July, the earliest corn will begin to reach maturity within 4-6 weeks. For irrigated corn, the question of when to quit irrigating always comes to mind. We want to maximize yield and water use efficiency, thus not irrigating any more than we have to in order to finish out the crop. […]

With temperatures predicted to be 100°F and heat index over 100°F this week, the question of “what is this heat going to do to my corn?” is always on people’s minds. When temperatures are consistently above 87F during corn growth stages VT (Tassel) through Maturity (R6), significant negative impacts on corn yield and development can […]

From Dr. John Mueller, Extension Nematologist/Plant Pathologist: Things are picking up speed in the world of corn foliar diseases. Dr. Kemerait who is my counterpart in Georgia is now reporting Southern rust on corn in Wayne County Georgia.  Wayne County is in Southeast Georgia.  That is 150 miles from the Edisto REC.  With current rain […]

From Dr. John Mueller: Southern rust has been found in two counties, Tift and Seminole, in southwest Georgia. The normal pattern is for southern rust to “blow up” across GA to SC. Simply put, the current weather pattern is perfect for this to happen.  Things could happen quickly! If your corn is at or past tasseling, […]

From Dr. John Mueller (Extension Nematologist and Pathologist) I am not about to comment on what type of weather everyone has endured over the last month other than to say some of you are still in a mild drought and those of us at Edisto REC got 12 inches of rain in May and 5 […]

As we move into the first week of June, corn that was planted “early” (March) is likely now tasseling or will be soon. This is a reminder that water demand in corn is at its peak, using 2.1 inches per week. The forecast is favorable for rain across the state over the next two weeks, […]

As we near the end of May, our earliest planted corn in the state is approaching tassel (VT) and reproductive growth, and our latest planted corn is near the V5 growth stage. Top/Side-dress nitrogen applications are now on most producers’ minds and actively going out where we can apply in between rain events. A few […]

Save the date for the 2025 Corn and Soybean Field Day held at the Clemson Edisto Research and Education Center in Blackville SC. More information will be available soon!

Clemson Cooperative Extension Service has deployed the Clemson Extension Weather Network. This project was conceived in 2020 in response to the lack of weather data being reported in/around agricultural production.​ Of the 51 stations installed, 42 (82%) were close to a production area. While the presence of weather data is critical for agricultural decisions, decision aids and tool […]

Much of South Carolina is now receiving some timely rainfall for corn. A lot of our corn was planted on time and in some cases earlier than the last few years due to good field conditions and soil moisture. The corn crop in SC is now considered planted, and most seems off to a good […]

The results of these trials are […]

As we move into the 4th of July weekend, a quick update on where we stand. Scattered showers and storms provided some rainfall over the last week which has helped our dryland situation in cotton, soybean, and peanut. Most of the dryland corn crop tasseled (pollinated) and began reproductive growth during the pop up drought […]

Surviving on tenths of rain is all we are doing right now across SC and the SE USA. High pressure in the North continues to drive moisture to the Gulf and away from the SE at a very water critical time for corn especially. Where irrigation is available, growers need to continue to run pivots […]

As of this week approximately 60% of our corn crop is silking. Tassel/R1 (Silk) is the most water sensitive growth stage of corn, if irrigation is available we need to ensure that we are irrigating corn 2 inches per week minus what is captured through rainfall.  In terms of our non-irrigated acreage, yield will suffer […]

I am sure by now everyone has heard that they have found Southern rust on corn and Soybean rust on kudzu in southwest Georgia. There has been a strong weather pattern of winds and rain blowing from the southwest towards us so it is possible diseases of all types could come in on a storm.  […]

Knowing the correct growth stage on corn and soybean is critical to proper input management. Two Land Grant Press articles were written to serve as a visual guide on how to properly ID both corn and soybean growth stages throughout their lifecycle. The following links will direct you to these Land Grant Publications: Visual Guide […]

The 2024 Corn and Soybean Field Day will be held at Edisto REC in Blackville, SC on Thursday July 25th. The program will start at approximately 8:30 and conclude with a provided lunch on-site. Field Day Flyer A detailed agenda will be available around the first of July.  If you have any questions please contact […]

Corn across SC is at various growth stages and experiencing a wide range of environmental conditions. Much of the state had abundant rainfall most of March, prohibiting field work and fertilizer applications to be made, delaying planting. In other areas, corn was able to get planted early and emerged looking great. As we shifted into […]

The results from the 2023 County Corn Hybrid Trials are now available. In 2023, we evaluated 12 different hybrids across eight locations across the state in both irrigated (4 locations) and non-irrigated (4 locations) cropping systems, the results from eight of those locations are included in the attached report. The results of these trials are […]

CORN: Foliar diseases: The only disease that spreads during this type of weather is Southern rust. But we are not seeing this yet in South Carolina. It is present in South Georgia. I am attaching a copy of the “Fungicide Efficacy for Control of Corn Diseases – January 2022” table put out by the “Corn […]

Soybean planting has quickly progressed over the last week, where rainfall has occurred. Hot, dry conditions continue for much of the state, though some places have been receiving a few pop-up showers to keep soil moisture levels adequate. In times of dry conditions keep an eye on fields that may not have received rainfall or […]

I am sure that many of you get various forms of information from other states. Dr. Kemerait in Georgia is very good about sending out updates several times a week, and I am sure there are other specialists who do the same. I thought I would try to send out what we are seeing primarily […]

Farmers across the state have now made it halfway through planting soybean in SC. Dry conditions continue in many places while some places have received rain to preserve soil moisture. Wheat harvest has begun in which approximately 1/3 of our soybean acres will follow. Stand establishment can be challenging following wheat stubble, residue, and straw; […]

Soybean planting continues, and we appear to be on track with our 5-year average. Several parts of the state were fortunate enough to get much-needed rain over the weekend and earlier this week. Hopefully, we can catch more rain this coming weekend to ensure adequate soil moisture for good germination, emergence, and PRE herbicide activation. […]

Soybean planting progressed well over the last week; we are 7 percent ahead of our 5-year average. Dry conditions are plaguing much of the state pausing planting in places where moisture has run out. As we continue through planting season, a few things to think about, first, make sure to plant soybean seed into the […]

Around 10% of soybean acres have been planted across the state, only a few percent behind the 5-year average. As cotton and peanut planting continues and wraps up, I anticipate soybean planted acres will increase rapidly depending on weather conditions. Dry weather across the state has allowed for fieldwork to be conducted but has delayed […]

This spring has been challenging, from increased input costs to low supply and shortages. The weather has been equally challenging across South Carolina so far in 2022. The majority of the corn crop was planted a week to 14 days later than last year due to cool temperatures, soils, and early season rains. We are […]

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 […]

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 […]

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 […]

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 […]

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 […]
