Let's first understand the role of the following corn growth control agents and brassinolide, and then see if they can be sprayed together. Corn growth regulators can control the elongation of corn cells and inhibit the growth of basal internodes, thus shortening the length of internodes and achieving the effect of dwarfing. Therefore, during the period from small horn mouth to big horn mouth, if the plant grows vigorously or even in vain, plant growth inhibitors should be sprayed in time to inhibit the excessive growth of the plant, delay its growth rate, and promote the stubble and shortened internodes.

Corn can be sprayed with king's agent at the 6- 10 leaf stage to shorten the internode distance, promote root development, Dozza several layers of roots and improve soil consolidation ability. Shortening the internode distance at the base of corn, to put it bluntly, means controlling the cell elongation, making it shorter, and there is no brassinolide: brassinolide is a plant growth regulator, which can effectively promote plant growth, quickly improve plant immunity, disease resistance and insect resistance, promote the wound healing left by pests and promote the repair of diseased spots. Crop phytotoxicity, brassinolide is still slow.

The commonly used pesticides to control corn growth mainly include paclobutrazol, uniconazole, chlormequat chloride, ethephon and so on. Can inhibit the synthesis of gibberellin in plants, and on this basis achieve the effect of controlling vigorous growth. Therefore, general epidemic prevention drugs and gibberellin have antagonistic effects. When spraying, it is required to spray evenly, and repeated spraying is not allowed. Rutin is a growth regulator, and the antidote is harmful. Therefore, it is recommended not to mix it with brassin. Because, according to the research of researcher Wang Liming of China Agricultural University, "gibberellin" and "brassinolide" are the most direct "influencing factors" to stimulate the height of plants-that is, crops containing "gibberellin" and "brassinolide" are sprayed during the growth of corn, so brassinolide cannot be sprayed together with pesticides. Why? Because brassinolide can divide or prolong cells, that is to say, make crops grow more vigorously, and the role of growth control drugs is to prevent crops from growing too much, which is contradictory, so they can't be sprayed together.
