Abstract

PURPOSE:To provide a herbicide containing 1,2,3,4-tetrahydro-alpha-naphthoic acid compound as an active component, having excellent activity to kill weeds especially in a paddy field at a low rate of application, free from phytotoxicity to gramineous crops, etc., and non-toxic to man, animal, fish and shellfish. CONSTITUTION:The objective herbicide contains 1,2,3,4-tetrahydro-alpha-naphthoic acid, its salt and/or its ester as an active component. The salt is e.g. a metal salt such as alkali metal salt, alkaline earth metal salt, zinc salt, copper salt, or amine salt such as ammonium salt, aliphatic lower amine salt, tri(lower alkyl)amine salt, alkanolamine salt, etc., and the ester is e.g. the compound of formula (R is a 1-18C hydrocarbon group which may have halogen, amino, nitrile, O of ether, or OH). The above active component is mixed with a carrier or adjuvant, prepared in the form of wettable powder, granule, emulsifiable concentrate, etc., and applied to paddy field or plowed land directly or after dilution.
