Abstract
The action mode and control effect of novel fungicide Boscalid on rape sclerotinia stem rot (Sclerotinia sclerotiorum Lib. de Bary) were studied in the laboratory and field. The results revealed that the protective effect of Boscalid at the dosage of 6.25 ~ 400.00 mg/L on rape was 81.66% ~ 100.00% , and its curative effect was 19. 82% ~ 78. 88%. Because Boscalid failed to well transfer basipetally from leaf to leaf, it had low protective effect on the leaves below or over the sprayed leaves. The effective duration of Boscalid after application was about 20 d. The field experiment showed that the control effect of Boscalid at 150 ~350 g/hm2 on rape sclerotinia stem rot reached 68.89% ~ 86. 84% , which was significantly better than that of 50% Carbendazim wettable power at 750 g/ hm2.关键词
