Our customers are reporting excellent pasture growth after applying Gibb-Gro.

Derived from the culture of the fungus Gibberellic Fujikuroi, Gibb-Gro contains the naturally occurring plant growth regulator gibberelllic acid (GA3). Gibberellic acid lengthens the cells of any plant, increasing the amount of drymatter grown in a pasture.
