What pesticides are used to promote rooting?

Hormonal Rooting Agents
Root-Inducing Agents: The primary active ingredient is indole-3-acetic acid (IAA). These agents promote plant growth and enhance adaptability. They are used in the production of crops such as fruit trees and vegetables, typically applied via seed soaking or foliar spraying; however, dosage must be carefully controlled to avoid injury caused by overuse.

Auxins: The primary active ingredients are indole-3-acetic acid and auxin esters. These stimulate plant and root growth and are used for crops such as grapes, loquats, and strawberries. Application is usually via foliar spraying or root soaking, though dosage requires careful attention.

Pyrimethanil (often referred to in this context as a fungicide): The primary active ingredient is pyrimethanil. It enhances disease resistance and stress tolerance in plants like fruit trees and vegetables while promoting growth. It is generally applied via spraying or irrigation, but timing and dosage must be managed to avoid adverse effects on the plants.

Carbendazim: Primarily used to control diseases such as root rot and *Sclerotium* blight, it also promotes plant growth. Used in fruit tree and vegetable production, it is commonly applied via seed soaking or root soaking; usage must follow instructions to prevent injury from excessive application.

Sanhuitai (Tri-peptide complex): A natural, plant-derived rooting promoter containing bioactive substances. It enhances nutrient absorption, growth vigor, and adaptability. It is typically applied during critical stages like sowing or transplanting, ideally via root soaking or direct application (smearing).

Bacillus subtilis: A common biological agent containing live *Bacillus subtilis* bacteria and their metabolites. It is primarily used to control diseases such as black spot and anthracnose while also promoting plant growth. It is generally applied by directly smearing it onto wounds or spraying it onto the crop surface.
