Product Description

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]

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]

Uniconazole products can be sprayed onto plant foliage or applied to the soil.[2] After it is taken up by plant roots, uniconazole is translocated in the xylem. The restricted-entry interval for Concise or Sumagic is 12 hours.[4][3]

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]
