Note: Gibberellic acid is easily decomposed by alkali and cannot be mixed with alkaline substances. The prepared gibberellanic acid solution can not last long, so as not to lose activity and affect the efficacy. Use in strict accordance with the recommended concentration, do not arbitrarily increase the concentration of medication, so as to avoid side effects. When gibberellic acid is used to promote fruit growth, water and fertilizer must be sufficient. If it is properly combined with growth inhibitors, the effect is more ideal. After gibberellanic acid treatment, it is not suitable to apply medicine in the field of barren seeds increased. The safe harvest interval on the general crop is 15 days, and the crop is used no more than three times per season.
