Abstract
The toxicity of a new fungicide, code named JS399-19 (2-cyano-3-amino-3-phenylancryic acetate), against20 Fusarium graminearum isolates was investigated in laboratory studies. JS399-19 showed equivalent activityagainst carbendazim-sensitive (MBC-S) and carbendazim-resistant (MBC-R) isolates, with mycelial growth inhibitionEC50s of 90 ± 21 and 97 ± 35 μg/L for MBC-S and MBC-R isolates, respectively. JS399-19 at 500 μg/ml providedexcellent protective and curative activity in controlling wheat scab of detached wheat heads, although it was notabsorbed by peduncles or was poorly translocated within peduncles. Field studies were conducted to determineefficacy of JS399-19 in controlling wheat scab and the development of carbendazim-resistant populations of F.graminearum. Wheat scab control was 72.2 and 86.1% when JS399-19 at 375 g a.i./ha was applied once and twice,respectively. JS399-19 at 563 and 375 g a.i./ha provided control equivalent to that of carbendazim at 563 g a.i./ha. Thefrequency of carbendazim resistance increased from 2.9 to 14.8% in plots treated with carbendazim, while resistancefrequency was only 0-1.4% in plots treated with JS399-19. JS399-19 appears to be a good candidate for controllingFusarium disease in the field, especially in areas where MBC-R fungal populations have developed.
