Based on ‘Guide book of Pesticide’, 454 herbicide items were registered. Among them, paddy field herbicides were 301 items, followed by lawn herbicides (55 items), upland herbicides (54 items, including orchards) and non-crop land herbicides (35 items). Among 112 herbicidal ingredients registered, the most was acetolactate synthase (ALS) inhibitors (Group B) including sulfonylureas (26 ingredients) and followed by mitosis inhibitors (Group K3, 15 ingredients), PPO inhibitors (Group E, 12 ingredients). Sufficient herbicide items were registered in major crops such as rice, grass in lawn, soybean, hot pepper, and etc. However, herbicide items registered were imbalanced between pre- and post-emergence herbicide items in case of some minor crops (e.g., perilla). Authors suggested that herbicides should be registered based on the experimental crop-toxicity and -residue data for farmers’ and end-users’ safety and pre- and post-emergence herbicides in a crop should be balanced for the efficiency of weed management.
