The article presents the herbicidal, defoliating, fungicidal properties of the synthesized derivatives of benzoxazolinones and benzoxazolinethions. It was shown that 3-alkylbenzoxazolinones, 3-alkyl-6-halobenzoxazolinones and 2-alkylthiobenzoxazoles exhibit herbicidal action during the growing season of plants, and they also cause cotton leaves to drop up to 70%. It was found that 3-alkylbenzoxazolinones and 2-alkylthiobenzoxazoles exhibited fungicidal activity against the pathogen, Fugarium oxyporum and Verticillum dahlia. Among them, 2-methylthiobenzoxazole inhibited spores of the fungi Verticillum dahlia by 96.4% and benzoxazolyl-2-carbamic acid butyl ester by 65%. These compounds exhibit fungicidal action against the pathogens of powdery mildew on cucumbers - Erysiphe cichoraceorum and powdery mildew on wheat - Erysiphe graminis, approaching the control Karatan. Apparently, these compounds are chemicals of contact action.
