2,4,5-Trichloro-6-bromo/iodo, nitro/phenyl carbamates have been prepared by reaction of 2,4,5-trichloro-6-bromo/iodo, nitro/phenyl chlorocarbonates with amines or by reaction of carbamoyl chloride with sodium 2,4,5-trichloro-6-bromo/iodo, nitro/phenolate, and the thiocarbamate esters have been prepared by reaction of O-(2,4,5-trichloro-6-bromo/iodo, nitro/phenyl) ester of chlorothiocarbonic acid with amines. IR and UV spectra of the synthetized compounds have been interpreted. The compounds have been tested for contact and systeme insecticidal, acaricidal, ovicidal, fungicidal and herbicidal activity. The highest fungicidal activity has been observed against powdery mildew disease.
