Structural formula: 

Application:  Forchloefenuron is a cytokinin, which improves fruit size, fruit set, cluster weight and coldstorage in grapes and kiwifruits. Forchlorfenuron acts synergistically with natural auxins to promote plant cell division and lateral growth. This plant growth regulator causes an increase in. berry or fruit size, including varieties not tolerant to gibberellic acid (certain grape varieties andkiwi). Application rates are extremely low. For grapes, lower use rates minimize harvest delay,while the higher use rates of 8 to 10 grams active ingredient (a.i.) per acre (A) maximizes berrysize and harvest delay. For kiwi fruit, application rate ranges from 2 to 8 grams a.i./A.
