South Korea amends Plant Protection Act to boost domestic pesticide development

South Korea has promulgated an amendment to the Plant Protection Act aimed at reducing reliance on imported raw materials for pesticides used to combat fire blight. The amendment, which will take effect on April 28, 2025, allows for the use of target pests and diseases for testing, research, and pesticide manufacturing upon receiving government approval.

Fire blight, a bacterial disease affecting apple and pear trees, has caused significant damage to orchards, with 135 farms and 55.4 hectares affected last year. Currently, the pesticides used to control the disease rely heavily on imported active ingredients. The Ministry of Agriculture, Food and Rural Affairs expects that domesticating the development of these agents will diversify control methods for farmers and reduce public control costs.

To prevent biological risks, strict management obligations are imposed. Unauthorized leakage or removal of pests is prohibited, and all materials must be destroyed after use. Violators face up to three years in prison or fines of up to 30 million won. The amendment also establishes a basis for the re-delegation of authority to streamline the permit process.
