Gibberellic Acid (GA3) is a plant hormone that promotes stem and leaf growth, reduces the shedding of cotton buds and bolls, increases barley yields, and improves fruit set rates for crops such as grapes, citrus, and pears.

To improve fruit set in sweet cherries, a Gibberellic Acid (GA3) solution at a concentration of 20–40 mg/kg can be sprayed during full bloom, or a 10 mg/kg solution can be applied 10 days after flowering. Methods to promote cherry fruit growth include:

The scientific application of plant growth regulators to manage the growth and development of fruit trees represents a new approach to producing high-value fruit. These regulators are versatile: they can either promote seed germination or prolong dormancy; stimulate shoot elongation or inhibit/delay shoot growth;

Extensive trials indicate that most plant growth regulators have a noticeable effect on the green foliage of plants. Among them, Mepiquat chloride, Chlormequat chloride, and Paclobutrazol are the most effective.

Forchlorfenuron (KT-30) is often used in combination with gibberellin. Trials have shown that spraying Kyoho grape clusters once with a mixture of Forchlorfenuron (KT-30) and gibberellin—10 and 20 days after full bloom—allows seedless berries to grow to the same size as seeded ones, increasing fruit size by up to 50%.

Physicochemical Properties and Identification of Natural Brassinolide,White crystalline powder; melting point 256–258°C; solubility in water 5 mg/kg; readily soluble in organic solvents such as methanol, ethanol, and acetone.

With the modernization of agriculture, herbicides have played a vital and irreplaceable role in controlling farmland weeds and protecting agricultural production.

Mepiquat chloride is used on a wide range of crops, including cotton, wheat, rice, peanuts, corn, potatoes, grapes, vegetables, legumes, and flowers.

When formulating products, customers typically consider the pH levels of fertilizers, which can limit their choice of plant growth regulators. Brassinolide is a novel regulator with a neutral pH, allowing it to be combined with fertilizers and pesticides across the entire pH spectrum—whether acidic or alkaline.
