The mixing of plant growth regulators and fungicides depends on the mechanism of action of the agents, systemic conductivity, complementarity of the objects of control, and whether antagonism will occur after mixing. In some cases, such as to achieve the purpose of disease prevention or enhance plant disease resistance, promote plant growth or cultivate strong seedlings

Naphthalene acetic acid (NAA) is an auxin plant regulator. It enters the plant body through leaves, tender epidermis and seeds, and is transported to the parts with vigorous growth (growth points, young organs, flowers or fruits) with nutrient flow, significantly promoting the tip development of the root system (rooting powder), inducing flowering, preventing falling flowers and fruits, forming seedless fruits, promoting early maturity, increasing production, etc. It can also enhance the plant's ability to resist drought, cold, disease, salt and alkali, and dry hot winds.

Indole-3-butyric acid (IBA) is a plant growth regulator that can promote plant growth and development, make plants more luxuriant and strong, and improve plant immunity and stress resistance.

Brassinolide (BRs) is an effective plant growth regulator used to alleviate pesticide damage. Brassinolide (BRs) can effectively help crops resume normal growth, quickly improve the quality of agricultural products and increase crop yields, especially in alleviating herbicide damage. It can accelerate the synthesis of amino acids in the body, make up for the amino acids lost due to pesticide damage, and meet the needs of crop growth, thereby alleviating pesticide damage.
