Abstract
Bedding plants are usually grown in flats, but if they are not moved to market on schedule, the stems elongate and the plants become unsalable.
To reduce the problem of elongation, a new growth retardant (uniconizole) was applied to bedding plants.
The bedding plants used were wax begonia, geranium, impatiens, marigold, pansy, petunia, snapdragon, vinca and viola.
Uniconizole was applied as a foliar spray at rates ranged from 0.25 to 100 mg/l (active ingredient). Two classes of sensitivity to uniconizole were established based on the growth response of the bedding plants.
Class 1 was very sensitive to uniconizole.
The growth of impatiens, vinca, viola and wax begonia were retarded adequately using uniconizole as a spray at rates of 1 to 5 mg/l.
Wax begonia was the most sensitive to uniconizole; it required only 0.5 mg/l to achieve adequate height reduction.
Class 2 was less sensitive than class 1, and required 10 to 20 mg/l rates for adequate height reduction.
Plants in this class were geranium, marigold, pansy, petunia, and snapdragon.
Of the species tested, snapdragon required the highest rate of uniconizole requiring at least 20 mg/l for adequate height reduction.
