How to Use GIBB-GRO

GIBB-GRO naturally derived growth promoter can be used on a 3 – 4 weekly cycle. Applications of Gibb Gro are best made in Autumn and spring when the soil temperature is likely to be in the range of 6 – 13 degrees C.

Applications of Gibb-Gro gibberellic acid should be made 1 – 5 days after grazing, ensuring maximum foliar uptake. Gibb-Gro is best suited to rotationally grazed pastures.

Soil moisture and fertiliser levels must be adequate to support increased pasture growth. Do not apply gibberellic acid to rank, ungrazed, pasture less than 1-year-old or on paddocks containing livestock.

Use Gibb-Gro with Urea to reduce your Nitrogen usage

Buy GIBB-GRO gibberellic acid to increase production and reduce nitrogen addition.  This will save you money.  If you want a cheap cost-effective gibberellic acid solution then using Gibb Gro with Urea or other Nitrogen sources is the solution.  If you are normally using 70-80kg/ha of Urea (32-37 units/ha) you can significantly reduce your Urea use by using a combination of GIBB-GRO and Urea.

We have many customers that have reduced nitrogen input down to 18 units/ha (40kg Urea per hectare) when using GIBB-GRO at the recommended 9g/ha.  Not only does this allow more additions of Urea while still remaining under the 190 unit/ha Nitrogen levels but it also saves you money.  

Gibb-Gro Application Rates

Apply at 9g/ha GIBB-GRO + 25ml Gibb-Gro Wetter per 100-200L water.  Apply a minimum of 100-200L per hectare.  Apply Gibb-Gro (GA3 gibberellic acid 90%) when soil temperatures are above 6-8C.

Put one scoop (9 grams) per hectare into your spray tank first. Use only the enclosed scoop. Do not use any other scoop or spoon designed for another type of Gibberellic. Overflowing of the scoop does not mean more grass growth.

Add water while stirring. Then when you are almost at the required water level add the wetting agent and finish filling with water.

For example; To spray 3 hectares use three scoops of Gibb-Gro. Place these into your empty tank, and add water while stirring briskly. When you are about 50 litres short of the required amount of water, add the wetting agent and fill to the level you need. (The wetting agent is put in last to avoid foaming). The label on the wetting agent will tell you what amount to use of that product but for Gibb-Gro WETTER this is 25ml/100L water.

Apply a minimum of 100 litres per hectare.
