Abstract

To promote healthy-seedling growth, the effects of various concentration of diniconazole treatments between foliar spraying and drenching irrigation on growth inhibition of plug seedlings were evaluated in cucumber and Korean zucchini. As a result of this research, plant height, hypocotyl length, leaf length and leaf width of all the crop seedlings were decreased significantly as concentration of diniconazole treatment increased in both the foliar spraying and the drenching treatment. At the time of seedling shipment the optimal concentrations were determined to be 20 ㎎/L for foliar application and 1.25 ㎎/L for drench application in cumber, whereas in Korean zucchini, 20 ㎎/L to 37.5 ㎎/L for foliar application, and 1.25 ㎎/L to 2.5 ㎎/L for drenching treatment. The drench application was found to sustain the growth-inhibitory effect on seedlings even at concentrations approximately 16 times lower than those used in foliar spraying. Moreover, the inhibiting effect for seedling growth by the irrigation treatment was sustained until shipment time of the plug seedlings. Thus, the drenching treatment was shown to be more effective than the foliar spraying to raise healthy seedlings between cucumber and Korean zucchini.
