GIBB-GRO is a naturally occurring growth promoting substance obtained from the culture of of the fungus ‘Gibberellic Fujikuroi’ and contains the naturally occurring gibberelllic acid GA3.  Expect a big boost in pasture growth, when used as directed.

Clients report excellent pasture growth after applying GIBB-GRO and there are many scientific papers and New Zealand and international trials to support the use of Gibb-Gro on pasture and also as a boost for seed germination.

Especially useful is the ability to be able to reduce Nitrogen inputs when treating with Gibb-Gro gibberellic acid.

When comparing to other products remember that most liquid Gibberellic Acids are only 40% not 90% like Gibb-Gro.  So if you currently buy Pro Gibb (1) or other 40% liquid gibberellic acids as a growth promoter then you should look at the cost per hectare and buy Gib Gro and give it a go.

Gibb-Gro is a premium gibberellic acid growth promoter and combined with Gibb-Gro wetter a wetting agent for gibberellic acid you can reduce you urea usage dramatically and still achieve quick and improved pasture growth over 21 days.
