Mepiquat chloride is a plant growth regulator primarily used to inhibit excessive vegetative growth in crops, promote reproductive growth, and enhance yields. It functions by regulating the hormonal balance within the plant, thereby controlling the overgrowth of stems and foliage, and boosting photosynthetic efficiency.

at low concentrations, 4-chlorophenoxyacetate (4-CPA-Na) acts as a plant growth promoter; its effects are particularly pronounced in dicotyledonous plants. However, at high concentrations, it exhibits an inhibitory effect instead. It is applied to crops such as tomatoes, various vegetables, and peach trees.

KT-30 exerts a significant promoting effect on cell division in wounded tissues; it facilitates organ formation and protein synthesis, causing cells to expand rapidly. When solanaceous fruits and similar crops are treated with KT-30, their growth rates undergo miraculous changes: for instance, cucumbers can grow by 5 cm per day, kiwifruit can increase in volume by 80%

0.3%–0.5% Urea + 0.2% Monopotassium Phosphate + Brassinolide
Functional Foliar Fertilizer containing Plant Immunity-Activating Proteins (e.g., "Weidali")
Functional Amino Acid/Humic Acid Foliar Fertilizer (containing Chitosan Oligosaccharide) + Monopotassium Phosphate

Atonik improves the absorption efficiency of nutrients such as nitrogen, phosphorus, and potassium; it also mitigates antagonistic interactions between fertilizers, thereby boosting fertilizer efficacy by over 30%.

To improve the utilization efficiency of pesticides, one may select plant growth regulators that possess synergistic effects. According to authoritative public sources, the following regulators have been widely verified to effectively enhance pesticide absorption, penetration, or efficacy

Indole Acetic Acid (IAA) Foliar Spray
Atomization Equipment Requirements: Droplet diameter ≤ 100 micrometers.
Optimal Time: After morning dew dries or in the evening 16:00-18:00.
Spraying Techniques: Focus on spraying the shoot tip growth point, avoiding periods of high temperature and strong sunlight.

Forchlorfenuron is a plant growth regulator primarily used to promote cell division, preserve flowers and fruits, and enlarge fruits, effectively improving fruit set rate and fruit quality.

Prohexadione calcium is used to control excessive vegetative growth and prevent lodging in soybeans,The key is to apply it during the early flowering stage. This effectively promotes flowering and pod setting, prevents lodging, and increases 100-seed weight and protein content.
