Brazil OKs Iharabras’ Viviful
Brazil has approved the sale of Iharabras’ plant growth regulator, prohexadione-calcium. It is the first registration of the active ingredient in Brazil. The ai will be marketed as Vivful, but the company has yet to target a launch, it told Agrow. Viviful is for use as a foliar application on apples, cotton, potatoes and ornamentals. The national health surveillance agency, the Anvisa, recommended its approval earlier this year, subject to the submission of new teratogenic studies on rabbits within 18 months ( Agrow No 568, p 19). Prohexadione-calcium was developed by Kumiai Chemical and launched in Japan, as Viviful, on rice in 1994.
