Abstract

The preparation of 2,4-diaza-1,3,5-pentanetrione compounds were described. The fungicidal effects of these compounds on the mycelial growth of the isolate, Phoma eupyrena were carried out by invitro experiment. The results show that the response to treatment depended not only on the concentration of the compounds used and duration of inoculation but also on the chemical constitution. All the compounds tested were effective at concentrations greater than serial dilution 10^-2. At lower concentrations, they were not too effective. The compounds were very active againstP. eupyrena.

Key words: Synthesis, fungicidal, 2,4-diaza-1,3,5-pentanetrione, Phoma eupyrena
