General Information
Ponnax plant regulator is a foliar-applied plant regulator for use on Concord and Niagara grapes only. Ponnax can modify the grape plant by regulating its growth and development. Ponnax may cause one or more of the following effects: reduction of intermodallength, reduction of can length, darker green leaf color, and increased berry set (more berries/cluster). Some ofthese effects can translate to improved yield potential.
