As South Carolina corn enters the critical tasseling and pollination period while soybean planting continues, growers are managing one of the more challenging weather years in recent memory. Much of the state experienced severe drought conditions earlier this season before receiving excessive rainfall and flooding in recent weeks. These weather extremes can have lasting effects […]

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 […]

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 […]

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 […]

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 […]

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 […]

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, […]

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!

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 South Carolina Corn and Soybean Growers Meeting will be held on December 17th, 2024 at the Santee Conference Center. Come hear research updates from the Corn and Soybean Boards, policy updates from American Soybean Association and National Corn Growers Association and visit with our many sponsors in the trade show! Pesticide and CCA credits […]

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 […]

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 […]

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 […]

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 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 […]
