If you drive past a farm at sunrise these days, you might see a farmer hunched over a seed planter, running a hand through a bucket of pale coated seeds like a wizard checking a potion. Every time that happens, there\u2019s a good chance that bucket has been treated with one of the products we spend most of our days talking about: seed treatment fungicides. Let\u2019s cut through the hype and the half-truths floating around farming groups and backyard garden forums\u2014yes, there absolutely are fungicides made specifically for seed treatment, and they\u2019re one of the quietest, most powerful tools we have to keep crops healthy before they even push through the soil. Fungicide<\/a><\/p>\n

<\/p>\n

I\u2019ve been in this game for 12 years, starting on a small commercial farm in southern Illinois and moving into supplying specialized fungicide formulations to growers across the Midwest. Back when I first started, seed treatment was an afterthought\u2014farmers would dust their corn or soybean seeds with a generic fungicide if they remembered, and most of the time it did nothing because it didn\u2019t stick or protect the right threats. Now? It\u2019s a $2 billion global market, and for good reason.<\/p>\n

Let\u2019s start with the basics that matter to anyone who\u2019s ever placed a seed in the ground. Seeds are fragile. They don\u2019t just have to sit in soil and wait for water and sun\u2014they\u2019re surrounded by a whole community of microbes, some helpful, some not. The bad ones? They include things like Pythium, Phytophthora, Fusarium, and Rhizoctonia. These aren\u2019t just \u201cmold\u201d in the generic sense\u2014they\u2019re soil-borne pathogens that feed on the seed\u2019s stored energy before it can even send out a root. If a seed gets attacked by Pythium in cold, wet soil in April, it can rot before it ever germinates. That\u2019s a stand loss, and stand loss early in the season can cost a farmer 10 to 20 bushels per acre before they even pull a single combine harvester.<\/p>\n

Seed treatment fungicides are different from the big spray fungicides you see applied mid-season to corn or wheat. They\u2019re formulated to stick to the seed coat, not wash off when the seed is in the planter or sitting in wet soil. They\u2019re also tailored to be taken up by the emerging seedling, so they protect the young root system for the first 2 to 4 weeks when it\u2019s most vulnerable. Think of it as a bodyguard for the seed\u2014only it\u2019s not guarding against people or burglars, it\u2019s guarding against tiny, invisible fungi that can ruin a whole planting before it even gets started.<\/p>\n

Now, I know what a lot of growers are thinking: \u201cDo I really need this? I rotate crops, I till my fields, that should keep pathogens down.\u201d Crop rotation and tilling are critical, but they don\u2019t eliminate these pathogens. Pythium can survive in soil for years, even when you\u2019re planting a non-host crop. And in recent years, we\u2019ve seen more and more cases of Fusarium and other pathogens developing resistance to older, single-mode-of-action fungicides. That\u2019s why we formulate seed treatments with different modes of action\u2014sometimes two or three, mixed together\u2014so pathogens can\u2019t adapt as easily.<\/p>\n

I recently worked with a 3,000-acre corn and soybean farmer in Indiana who had a terrible season in 2021. His field had heavy stand loss because of late blight, and he lost about a quarter of his planting. The next year, he switched to our seed treatment for his soybeans and a competitive product for his corn. His stand that year was 98% complete, and he ended up with 18 more bushels per acre than his five-year average. He told me it was the cheapest input he\u2019d bought all year\u2014because a 10-bushel per acre gain pays for the treatment three times over.<\/p>\n

But it\u2019s not just field crops. Vegetable growers, especially small-scale specialty ones, have caught on too. Last month, I met a family growing heirloom tomatoes for a farmers\u2019 market in Ohio who was losing 30% of her tomato seedlings to damping-off (that\u2019s the term for seedling rot from soil fungi). She tried everything\u2014neem oil, homemade compost, even letting the soil dry out between waterings\u2014until she tried a small batch of our tomato-specific seed treatment. She said she now has fewer than 5% of her seedlings dying, and she\u2019s doubled her crop.<\/p>\n

Now, let\u2019s get into the science, because I don\u2019t want to oversimplify this. Seed treatment fungicides aren\u2019t a one-size-fits-all product. We have different formulations for different crops, different soil types, even different regions. For example, the fungicides that work on corn against Fusarium graminearum (the cause of head scab) are different from the ones that protect soybeans from Rhizoctonia solani, which causes root rot. We also take into account the soil temperature at planting time\u2014if a farmer is planting in cold, wet soil, we\u2019ll recommend a treatment with stronger activity against Pythium, because that pathogen thrives in those conditions.<\/p>\n

Another thing that sets seed treatment fungicides apart: they\u2019re low-rate applications. You\u2019re not spraying gallons of product over acres of field\u2014you\u2019re coating each individual seed with a tiny amount of fungicide, measured in milligrams per seed. That means less product overall, less runoff into waterways, and lower environmental impact than foliar sprays later in the season. A lot of people don\u2019t talk about that, but it\u2019s a big deal for us as suppliers\u2014we work hard to make products that are effective for growers and safe for the environment.<\/p>\n

I also want to address the biggest misconception I hear all the time: that seed treatment fungicides can \u201ccure\u201d every problem once the plant is established. No, they can\u2019t. Once the seedling\u2019s root system is big enough to fend for itself, the fungicide breaks down, and that\u2019s when mid-season scouting and sprays come in. Think of it as an insurance policy, not a miracle cure. You don\u2019t buy car insurance because you expect to crash\u2014you buy it to protect you if something goes wrong. That\u2019s exactly what seed treatment fungicides do for seeds.<\/p>\n

Over the past few years, we\u2019ve also started developing seed treatment products that combine fungicides with other beneficials, like biologicals. These are living microbes that colonize the root system and help protect against pathogens, plus they improve nutrient uptake. It\u2019s a hybrid approach that\u2019s become really popular with growers who want to reduce their use of synthetic chemicals, while still getting the protection they need. Last year, we launched a biological seed treatment for wheat that\u2019s been tested in 12 states, and early data shows it reduces Fusarium head blight by 25% and increases yields by 7 bushels per acre, on average.<\/p>\n

But here\u2019s the thing I tell every grower I work with: not all seed treatment fungicides are created equal. A lot of big ag companies sell generic formulations that cut corners on formulation technology\u2014they don\u2019t stick well, they don\u2019t release at the right time, or they use older modes of action that pathogens are already resistant to. That\u2019s why partnering with a supplier that has on-staff agronomists who can help you match the right product to your specific fields is so important. We don\u2019t just sell a bag of fungicide\u2014we work with you to look at your soil history, your planting dates, your crop rotation, and recommend a treatment that makes sense for your operation.<\/p>\n

A few months ago, a small organic vegetable grower reached out to us, worried because she had to abandon half her pepper crop the year before due to seedling rot. She was nervous about using synthetic products, so we recommended our biological-based seed treatment for peppers, which is OMRI-listed for organic production. This past season, she told me she planted 10 acres of peppers and lost fewer than 2% of her seedlings. She was able to sell almost all her crop at the local farmers\u2019 market, whereas the year before she\u2019d only been able to sell half. That\u2019s the impact this can have, not just on large commercial farms, but on small businesses and family operations too.<\/p>\n

I know farming is hard. You put in long days, you invest thousands of dollars in seed, fertilizer, equipment, and labor, and one bad season can wipe out years of progress. Seed treatment fungicides aren\u2019t the answer to every problem, but they\u2019re a tool that works when used correctly. For too long, growers have treated seed treatment like an afterthought, something they can skip if they\u2019re on a tight budget. But when you do the math, the cost of a good seed treatment is usually $5 to $10 per acre, and the payoff in saved seed, higher stands, and better yields is far more.<\/p>\n

If you\u2019re a grower who\u2019s never used seed treatment, or if you\u2019ve tried products in the past that didn\u2019t work, I want to invite you to talk to us. We don\u2019t push one-size-fits-all solutions\u2014we take the time to learn about your operation, your challenges, and your goals, and we recommend a treatment that fits. Whether you\u2019re planting corn, soybeans, wheat, vegetables, or specialty crops, we have formulations designed to protect seeds from the pathogens that can derail your season before it even starts.<\/p>\n

At the end of the day, farming is about giving seeds the best possible start. You wouldn\u2019t plant a seed and leave it unprotected from pests and disease later in the season\u2014why would you do it for the first, most vulnerable weeks of growth? Seed treatment fungicides are a tried-and-true, science-backed way to give your seeds that head start.<\/p>\n
