The recent situations of sulphur-containing compounds which have been developed as agrochemicals for plant protection are reviewed from the standpoint of their use and biological properties in each field of fungicides, insecticides, acaricides and herbicides. In controlling plant diseases that are not easily controlled with the protectant fungicides such as the dithiocarbamates, many systemic fugicides including sulphur-containing compounds have been introduced commercially during the last 10 years. They are the oxathiins, thiabendazole, thiophanates and the other selective fungicides which are specifically effective against powdery mildew, soil fungal diseases and rice blast, respectively. In the field of insecticides, there are some new approaches to improve selectivity and toxicity in sulphur-containing compounds including organophosphates, oximcarbamates and natural toxin dervatives. The two new acaricides having the sulphur-containing group have been found from a series of diphenyl ether compounds. Although many commerical herbicides known so far genarally are used in pre-emergence treatment, recent advances in weed control have been made especially in post-emergence application with the selective type of sulphur-containing herbicides, such as the methylthio <I>s</I>-triazines, benzthiazoles, benzothiadiazine, sulphonamide derivatives and thiolcarbamates, etc.
