Farmers know that a strong crop starts long before the planter hits the field. Seed treatments and overtreatments are some of the most reliable ways to set corn and soybeans up for success. Protecting emerging plants, strengthening early root development, and helping crops push through early‑season stress. The PCT | Sunrise® Croprotek® lineup is designed to do exactly that.
Below is a quick breakdown of three Croprotek products that PCT | Sunrise offers. Croprotek seed treatments for corn and soybeans consist of: Premium ST, Standard ST, Soybean Seed Overtreatment, and Corn Seed Overtreatment. Each one followed by how they work together to support stand establishment and yield potential across your acres.
Croprotek Premium ST: Complete Soybean Seed Defense
Croprotek Premium ST is an all‑in‑one soybean seed treatment blend that protects seedlings where they’re most vulnerable — in cool, wet soils and early growth stages. The formulation combines three fungicides plus an insecticide to defend soybeans from a wide spectrum of threats including Pythium, Phytophthora, Rhizoctonia, Fusarium, seed decay, aphids, bean leaf beetle, wireworms, and seed corn maggot.
Premium ST also uses an industry-leading polymer that improves seed flowability in the planter and ensures consistent coating from seed to seed. This helps soybean seed get out of the ground faster and more uniformly. Something every farmer values in challenging planting windows.
Soybean Seed Overtreatment: Added Nutrition for Early Vigor
Croprotek Soybean Seed Overtreatment provides an additional layer of early-season nutrition on top of standard fungicide/insecticide treatment. This helps soybeans emerge more uniformly, develop stronger early root systems, and maintain better vigor under variable spring conditions.
This overtreatment includes key micronutrients like manganese, copper, iron, and zinc, along with seaweed extract, chitosan, and plant growth regulators. Which are all geared toward supporting photosynthesis, enzyme activity, stress mitigation, and root development. A specialized polymer helps everything adhere smoothly to the seed for reliable handling and planter performance.
Corn Seed Overtreatment: Nutrition That Supports Uniform Emergence
Croprotek’s Corn Seed Overtreatment focuses on delivering key nutrition right at planting to encourage uniform emergence, stronger early roots, and better stand establishment. This overtreatment includes zinc, manganese, copper, iron, seaweed extract, plant growth regulators, and chitosan. Which are all aimed at stimulating root growth, improving chlorophyll production, and helping young plants manage early stress.
Furthermore it also features BioBuild® BioST + R, a microbe team that supports nitrogen fixation and ammonification in the root zone. Which helps keep nutrient supply steady during crucial early stages.
Standard ST: A Fungicide Only Custom Blend for Soybeans
Croprotek’s Standard ST is a custom blend that combines three fungicide chemistries to provide crops with early season control of many seed-borne and soil-borne diseases encountered in soybean production. With a three fungicide mix using three families of chemistries along with a polymer and color formulated to deliver superior protection.
Standard ST delivers strong early-season protection by combining fludioxonil and thiophanate-methyl to guard seeds against rots and shield young seedlings from Rhizoctonia and Fusarium species. In addition, its elevated rate of metalaxyl enhances control of both Pythium and Phytophthora species, supporting healthier and more vigorous crop establishment.
How They Work Together for Your Acres
Each of these products play a role on its own, but together they create a strong, complementary approach to early plant health.
- Premium ST shields soybeans from early diseases and insects, providing dependable defense where emergence is most fragile.
- Standard ST is a fungicide only custom blend for soybeans.
- Soybean Seed Overtreatment adds nutrition and biological support that strengthens the plant’s foundation, promoting healthier, more vigorous stands.
- Corn Seed Overtreatment brings similar nutrition and stress‑mitigation benefits to corn, helping ensure even emergence and early season uniformity.
When growers use these Croprotek seed treatments for corn and soybeans, the combined effect is simple: more confident emergence, improved early-season resilience, and a stronger start that supports overall yield potential. Whether conditions turn cool, wet, or stressful, treated seed is better equipped to push through and establish a stand that can perform.
The Croprotek Lineup: Protection Across Every Growth Stage
These Croprotek seed treatments for corn and soybeans are a key part of PCT | Sunrise’s broader Croprotek product lineup. The Croprotek products are designed to defend crops from weeds, insects, disease, and nitrogen loss at multiple growth stages.
From early‑season seed protection to in‑season defense, Croprotek products help maintain plant health and reduce stress throughout the crop’s development. The goal is simple: support crop performance from planting to harvest, giving Sunrise customer‑owners a strong agronomic advantage year after year.
