Uses
Uniconazole is applied to plants to restrain their growth. It is often used on perennials to maintain a marketable size and/or delay flowering.[2] Leaves usually appear darker after application because uniconazole increases chlorophyll content.[1]
Commercial products
The following products labeled for application to ornamental plants as plant growth retardants in the United States contain uniconazole:
Sunny is an Australian product containing uniconazole that is labeled for application to avocado trees to improve fruit size and quality.[5]
Application methods
Reversing the effects of over-application
Over-application of any growth retardant can be devastating to a crop. One way to reverse excessive stunting is to apply gibberellins A4 + A7 and benzyl adenine. In the United States a product called Fresco is labeled for this use.[6]
