Application of Prohexadione Calcium as a Corn Growth Promoter

I. Mechanism of Action of Prohexadione Calcium

Prohexadione calcium is a plant growth regulator whose main components are oxadiazole and calcium ions. Oxadiazole promotes corn seedling growth, increases photosynthesis efficiency, inhibits harmful substances produced by photosynthesis, and improves light energy utilization. Calcium ions promote plant cell division and elongation, enhancing plant stress resistance and immunity. Therefore, prohexadione calcium can significantly promote corn growth and development, improve light energy utilization efficiency and yield, and enhance commercial characteristics and quality.



II. Application Methods of Prohexadione Calcium on Corn

Prohexadione calcium can be applied to corn through various methods, including spraying, irrigation, and seed soaking. Spraying is the most commonly used application method. Specific application methods are as follows:

1. Use different concentrations of prohexadione calcium at different stages of the corn growth period. Generally, a concentration of approximately 500mg/L of prohexadione calcium is used during the seedling stage, and approximately 1000mg/L during the growing stage.

2. Dilute prohexadione calcium to an appropriate concentration and spray evenly on the corn leaves. Be sure to spray on clear, windless days to prevent the drug from drifting and affecting its effectiveness.

3. Spray every 7-10 days, and spray 2-3 times in a row. Spraying is generally done in the morning or evening to avoid the effects of high temperatures and strong sunlight on the corn.



III. Precautions

1. Prohexadione calcium itself is low in toxicity and harmless, but excessive use may have negative effects on plants. Therefore, be sure to follow the instructions for dilution and application.

2. Among various application methods, such as spraying, irrigation, and seed soaking, spraying is the most commonly used method. However, protective measures must be taken during spraying to avoid any impact on the human body and the environment.

3. Prohexadione calcium should not be mixed with other fertilizers or pesticides to avoid affecting its effectiveness.

4. After using prohexadione calcium, be sure to closely monitor the growth of the corn and adjust the dosage and dosage promptly to ensure optimal results.

Prohexadione calcium has significant advantages in promoting corn growth and improving quality. Furthermore, its simple and easy use makes it a worthwhile option for growers.
