仙客来灰霉病田间消长规律及防治技术

Occurrence and control of Cyclamen persicum grey mould

通过田间观察,3月下旬至4月下旬移栽入盆的仙客来,5月下旬出现灰霉病病株,9月下旬发病逐渐加重,12月下旬至2月上旬为发病高峰期。种植环境和种植密度与发病有关,品种间发病有差异,生物农药农抗武夷菌素、多抗霉素、春雷霉素和化学农药腐霉利对仙客来灰霉病有较好的防治效果。

The symptoms of Cyclamen persicum grey mould appeared in late May after transplanted into pots from late March to late April. The disease worsened in late September and reached its peak from late December to early February. Growing conditions and density were relevant to disease occurrence and the incidence differed among vari- ous varieties. Both biological pesticides, including wuyiencin, polyoxin, kasugamycin, and chemical pesticides, in- eluding procymidone, had good control efficacy.
