BOOST: Mixture of GA (4+7)18g/L + 6-BA 18g/L

In “BOOST” containing two Plant growth regulators: gibberellic acid 4 and 7 (GA4+7), which cause cell enlargement and elongation, and 6-benzyladenine (6-BA) which promotes cell division.

Gibberellins and cytokinins are growth regulators specific to plants.

While 6-Benzyladenine is made by chemical synthesis, the gibberellins are produced by the process of fermentation, where a pure strain of the fungus Gibberella fujikorai is grown in an aseptic medium.

The two ingredients contribute to increase fruit size: 6-BA stimulates cell division, and GA4+7 causes cell expansion. These effects only take place in plant tissues and only during the very early development of the fruitlet. The result is a larger fruit with more cells and larger cells. In addition, the gibberellins help reduce fruit russet and improve overall fruit finish.
