Registration of Agricultural Chemicals

Under the Agricultural Chemicals Regulation Act, the Minister of Agriculture, Forestry and Fisheries registers agricultural chemicals only when they are found effective for plant protection and safe for health and the environment. Only registered ones can be manufactured, sold, and used.

Agricultural Chemicals Regulation Act (Act No.82 of 1948)

Registration Standards

The Minister of the Environment is responsible for setting registration standards regarding (i) Residues in crops, (ii) Residues in soil, (iii) Prevention of damage to flora and fauna, and (iv) Water pollution.

Of these, registration standards regarding (iii) and (iv) are set for each active ingredient by the Central Environment Council, and it is confirmed that the chemical, used as prescribed, will be unlikely to cause adverse effect on the environment. (See the figure below.)

Residues in Crops

Agricultural chemicals cannot be registered when the residue of their active ingredients on crops does not conform to the food standards of the Food Sanitation Act (Act No. 233 of 1947). When their active ingredients remain in forage crops, they cannot be registered when the residue on the livestock products produced using those forage crops does not conform to the food standards.

Residues in Soil

Agricultural chemicals cannot be registered when the residue of their active ingredients in soil are carried over to the succeeding crops and remain beyond the standards of the Food Sanitation Act.

Prevention of Damage to Flora and Fauna

Aquatic Animals and Plants

Agricultural chemicals cannot be registered when the Predicted Environmental Concentration (PEC) of their active ingredients in areas of public waters does not conform to the standards set by the Minister of the Environment based on the toxicity tests on aquatic animals and plants (fish, crustaceans, microalgae and aquatic plants, etc.).

Terrestrial Animals and Plants

Agricultural chemicals cannot be registered when the amount of their active ingredients that the terrestrial animals and plants (birds, bumblebees) living and growing around farmlands are exposed to does not conform to the standards set by the Minister of the Environment for each species, based on the toxicity tests on these animals and plants.

Water Pollution

Agricultural chemicals cannot be registered when the Predicted Environmental Concentration (PEC) of their active ingredients in areas of public waters does not conform to the standards set by the Minister of the Environment to prevent adverse effect on drinking water.

Reevaluations

A post-market reevaluation process has been introduced according to the revised Agricultural Chemicals Regulation Act enacted in 2018, in which the safety and other qualities of all the registered agricultural chemicals are reexamined on the basis of the latest scientific knowledge.

In detail:
1. Agricultural chemicals registered after the enforcement of the revised act (December 1, 2018) will be reexamined approximately every 15 years.
2. Agricultural chemicals registered before the enforcement of the revised act will be reexamined from 2021FY, according to the priority list*.
(*) Priority list on the reevaluation of existing agricultural chemicals
Taking into account the magnitude of impact on health and the environment, the order of reevaluation is determined according to the amount of each chemical used domestically.
