Product description:

Forchlorfenuron (CPPU) is a highly active cytokinin-like plant growth regulator that promotes chlorophyll biosynthesis, cell division, and cell expansion.

Groster a new synthetic phenyl urea derivative of cytokinin, increases plant growth by inhibiting cytokine oxidase, a regulator of cytokinin activity.

It acts synergistically with natural auxins to promote plant cell division and lateral growth.

Groster increases the size of berry, improves cluster weight and total yield of blueberries, grapes,kiwi, nuts and other crops.

It may improve fruit quality in cold storage condition and delay grape maturation.

The higher the rate of product applied, the greater the potential for maturity delay.

In grapes, it may prevent early-stage fruit dropping,reduce black drops and maintain the skin color and texture of the Grapes.

This product also boosts the quality and quantity of the Grapes by increasing the berry size and thus leading to spherical berries instead of oblong ones.

 

Application Mode:

Product efficacy requires thorough coverage of the flowers and/or fruit. Uniform spray coverage is essential to achieve the desired results.

For a better result, apply Groster under slow drying conditions, e.g. early in the morning, late in the afternoon, or at night, to ensure adequate uptake.

For best results, the water pH should be close to neutral, and always below 8.5.

 

Mixtures & Compatibilities:

– DO NOT apply Groster to plants under stress. If plants under stress are treated, the effect may be reduced.

– DO NOT use overhead irrigation until sprays of Groster have dried completely.

– DO NOT apply Groster if rain is expected before sprays have dried completely.

– DO NOT apply this product through any type of irrigation system.

–  Aerial application of Groster is prohibited.

– DO NOT treat fruit by dipping.

– Use of the dip method for Groster may result in residues exceeding tolerance restrictions.
