HARMFUL EFFECT REDUCTION AGENT FOR HERBICIDE, HERBICIDE COMPOSITION HAVING REDUCED HARMFUL EFFECT, AND METHOD FOR REDUCTION OF HARMFUL EFFECT ON CROPS

摘要

Disclosed are: a harmful effect reduction agent for a herbicide, which can reduce or suppress a harmful effect and can reduce an environmental load without requiring the use of multiple different types of herbicidally active components in combination; a herbicide composition having a reduced harmful effect; and a method for reducing a harmful effect on crops.The harmful effect reduction agent for a herbicide is characterized by containing, as the main component, a compound represented by general formula (I) (wherein R¹ represents a hydrogen atom, a hydroxyl group or a C4-C5 alkyl group; R² represents a hydrogen atom or a C4-C5 alkyl group; R³ represents a C4-C5 alkyl group; X represents a carboxyl group, an amino group, a hydroxyl group or a hydroxymethyl group; and Y represents a hydrogen atom or a hydroxyl group, wherein one of R¹ and R² represents a C4-C5 alkyl group). The herbicide composition having a reduced harmful effect is characterized by containing the harmful effect reduction agent for a herbicide and at least one specific herbicidally active compound.
