1. Background and Objective

Brazil's agricultural landscape serves as a high-pressure testing ground where products must withstand extreme heat, water stress, and complex soil conditions. To validate the efficacy of Coronatine under these real-world pressures, New Sun established a multi-region field trial network across key agricultural hubs, including Minas Gerais. The primary objective was to evaluate the impact of Coronatine seed treatment on soybean germination speed, stand uniformity, and early-stage plant vigor.

2. Trial Methodology

Location: Uberlandia and Araxá, Minas Gerais, Brazil

Crop: Soybean.

Treatments Compared:

Untreated Control: No seed treatment applied.
Competitor Product: Standard commercial seed treatment.
Coronatine Treatment: Applied as a professional seed treatment.

3. Field Trial Performance

A. Enhanced Germination Speed Index (GSI)

Quantitative data from the 2026 Brazil trials reveals that Coronatine significantly accelerates the germination process.

Superior GSI: Coronatine achieved a Germination Speed Index of 3.29, outperforming both the competitor product (3.02) and the untreated control (2.78).
Efficiency Increase: This represents an 18.3% increase in GSI compared to the control, ensuring crops emerge faster to capitalize on early-season moisture.

4. Stand Establishment and Population Density

Long-term tracking (6 to 12 days after sowing) demonstrates that Coronatine ensures a higher and more consistent plant population per row.

Visible Advantage at Day 6: Emergence is measurable as early as 6 days after planting, with Coronatine-treated rows showing more advanced growth.
Repeatable Uniformity: Across trial locations, Coronatine produced a significantly more uniform stand, reducing the number of gaps in the rows compared to the sporadic emergence seen in the control.

5. Morphological Development: Root and Shoot Analysis

Visual evidence collected 6 days post-planting highlights the physiological impact of Coronatine on early plant architecture.

Advanced Root Systems: Coronatine-treated seedlings exhibit more robust and expansive root structures compared to the control, facilitating better nutrient and water uptake from day one.
Superior Shoot Elongation: Treated plants demonstrated taller growth and more developed primary leaves (early vigor), providing a stronger foundation for subsequent growth stages.
