South Korea is applying a low-carbon, non-pesticide growth promoter to rice fields in Jeollanam-do to suppress the seed-coat spot disease [1, 2].
The initiative follows a severe outbreak of the disease that led to significant crop losses and required the government to pay approximately 500 billion KRW [1] in disaster relief funds nationwide.
The South Korean Prime Minister visited the affected rice-farming areas in South-Jeolla Province to oversee the response [1, 2]. The disease, known as 깨씨무늬병, has become a major threat to the national rice supply due to increases in rice diseases driven by climate change [1, 2].
Unlike conventional pesticides, the growth promoter focuses on strengthening the plant's natural resilience. Yu Seung-kwon, CEO of a crop-growth-promoter company, said the treatment improves root distribution. He said that by allowing roots to reach deeper into the soil and absorb a larger quantity of inorganic nutrients, the plants achieve an optimal defense against the seed-coat spot disease [1].
This approach aims to mitigate the impact of climate-driven agricultural threats while reducing the chemical footprint of rice production. The deployment in Jeollanam-do serves as a critical test for whether biological growth promoters can replace traditional chemical interventions in the face of worsening environmental conditions [1, 2].
The government's focus on low-carbon solutions reflects a broader strategy to stabilize food security without relying on synthetic pesticides that can harm the ecosystem. By increasing the mineral uptake of the rice plants, the promoter seeks to prevent the wide-scale crop failures that characterized the period following the Chuseok holiday in 2023 [1, 2].
“The disease, known as 깨씨무늬병, has become a major threat to the national rice supply due to increases in rice diseases driven by climate change.”
The shift toward non-pesticide growth promoters indicates a strategic pivot in South Korean agriculture to address climate-induced crop volatility. By prioritizing root health and mineral absorption over chemical eradication, the government is attempting to build systemic resilience into the food supply chain to avoid the massive financial burdens of disaster relief associated with future outbreaks.
