La producción de papa en Costa Rica enfrenta condiciones especialmente exigentes durante la época lluviosa, donde la humedad elevada incrementa la presión de enfermedades causadas por bacterias como Ralstonia y Xanthomonas. Estos patógenos representan una amenaza constante para la sanidad del cultivo, afectando productividad, vigor y uniformidad.

Against this backdrop, ClearLeaf held a Field Day in La Palmita, Cirrí Sur de Naranjo, hosted at the farm of producer Óscar Varela Acuña, who has been integrating GotaBlanca 500 into his management program to sustain crop health under intense disease pressure.

Background: Limitations of Previous Management
For years, Mr. Varela relied on conventional inputs to address bacterial challenges. However, these products often caused:
1. Plant stress, resulting in reduced vigor.
2. Temporary growth slowdown after application.
3. Tissue damage, complicating crop development and uniformity.

These issues led him to seek a solution that protected the crop without compromising plant physiology.

Adopting GotaBlanca 500
Mr. Varela transitioned to GotaBlanca 500, purchased from Colono Agropecuario Zarcero, replacing the inputs that previously stressed his plants. He emphasized several advantages of GotaBlanca:
1. It is gentle on the plant, without causing burns or growth interruptions.
2. It provides consistent protection against the bacterial problems present in his fields.
3. It helps maintain a uniform crop, even under high-humidity conditions.

El manejo aplicado por el productor consiste en:
👉 1 litro de GotaBlanca 500 por cada 200 litros de agua,
👉 con aplicaciones cada 4 días.

Field Observations During the Event
During the Field Day, participants were able to examine the treated plot and observe several notable characteristics:
1. Strong vigor and uniformity
Plants showed consistent growth, firm structure, and good vegetative development.
2. Healthy, resilient tissues
Tissues appeared firm and intact—an important trait in humid environments that can accelerate pathogen entry.
3. Reduced bacterial impact
The plot showed visibly lower symptoms associated with Ralstonia and Xanthomonas, two of the most aggressive bacterial threats in potato crops during rainy periods.
4. No stress after application
Unlike previous inputs, GotaBlanca 500 did not cause stress or adverse effects on the plants following application.

Closing Remarks
At the end of the visit, Mr. Varela expressed his satisfaction with the performance of GotaBlanca 500, noting: “The plant does not get stressed and stays uniform from start to finish.”

His experience demonstrates how a more gentle and effective approach can help maintain crop health under high disease pressure. GotaBlanca 500 continues to position itself as a reliable tool for potato growers seeking stable performance and protection against the main bacterial challenges in the field.
