Abstract：‘Jinghu36 ’was one of the important varieties in greenhouse production in winter in North China. Effect of E,R(-)-diniconazole (hereinafter referred to as diniconazole) on controlling excessive growth in early growth period and powdery mildew in middle and later growth period for this variety in greenhouse and the best concentration has been studied in this research. The results showed that with the increase of the concentration, the effect of the four diniconazole reatments to control tended to rise, but none surpassed the treatment of 75 mg·kg-1 paclobtrazol treatment. For plant height, fruit number and yield, the treatment of 90 mg · kg-1 diniconazole was the best concentration, otherwise, the treatment of 75 mg · kg-1 paclobtrazol treatment significantly depressed the plant growth that resulted lowest yield. Each diniconazole treatment showed better effect than the treatment of 150 mg · kg-1 triadimefon treatment and the 90 mg · kg-1 diniconazole treatment was the best for curative effect and yield.
