Efficacy of Rheum officinale liquid formulation on cucumber powdery mildew
چکیده انگلیسی

Rheum officinale liquid formulation, the ethanol extract from roots of R. officinale Baill., formulated as physcion 5 g l−1 aqueous solution (AS), has been commercialized in China for controlling cucumber powdery mildew (Podosphaera xanthii (Castagne) U. Braun & Shishkoff). The efficacy of the product was evaluated in pot tests under controlled conditions and in open and protected fields in China over 2 years. In most trials, the efficacy reached above 80% at the rates of 10–50 mg a.i l−1 water after three applications and at the rates of 20–50 mg a.i l−1 water after two applications. The cucumber fruit yield in the product treatment was as many or more as triadimefon treatment, and over 53.1% compared to the untreated control. These results showed that Chinese rhubarb extract could be an effective alternative plant protecting agent in the integrated and biological management of cucumber powdery mildew.
