Abstract

The relationship between chemical structure and biocidal activity of new derivatives of phenylisothiocyanate. was evaluated against fungi: Rhizoctonia. solani, Fuarium. oxysporum Botryodioploda theobromae and bacteria: Pseudomonas. and Agrobacterium tumefacineseas as well as their inhibitory power to enzyme systems: dehydrogenase (from bacteria), PME and Mg ATPaeses (from Fungus). These derivatives had different levels and modes of toxicity on the fungi and bacteria growth as well as enzyme inhibition Obviously, the analog 3- 3-nitro-4-amino was very active as biocide and it was as toxic as the recommended pesticides followed by 2-amino-5-nitro analog, while 2-nitro-4-amino was the Lowest one. The inhibitory power of the compounds was parallel to their toxicity to fungi and bacteria. The ATPase activity was less sensitive than the other enzyme systems.
