Will an excessive amount of corn growth regulator cause a reduction in corn yield? I can tell you clearly: it absolutely will. The problem of using too much growth regulator does not only occur in corn; it also happens frequently in peanuts, wheat and rice. In production, the dosage and timing of growth regulator application must be grasped accurately, otherwise it will not only be difficult to achieve a yield increase, but will also lead to a yield reduction.

The harm of excessive dosage

An excessive dosage of growth regulator will cause excessive inhibition of plant growth vigor, making corn plants grow slowly. Even in cases of severe overdose, corn plants may even die. Generally speaking, a slight overdose will also make corn plants shorter, with premature aging and poor growth. Slight phytotoxicity may still be reversible, but for some corn with a severe overdose, once the harm is done it is irreversible. A yield reduction is then unavoidable.

The role of growth regulation

The application time of growth regulator is basically at the jointing stage, because the purpose is to control the internode distance of corn and improve the lodging resistance and stalk-breaking resistance of the corn stalks. This is also a major problem existing in current corn production. In addition, it can also promote a well-developed root system and improve the utilization rate of water and fertilizer. And most importantly, because the internode distance is shortened, it can also move the ear position downward and improve the stalk-breaking resistance of the plant.

Precautions for growth regulation

In corn production, the timing of growth regulation must be strictly grasped, and it is basically at the jointing stage. In addition, in terms of dosage, the instructions must be followed, and the dosage must not be blindly increased or reduced. As for the spraying time, it can be chosen after 4 p.m., when the weather is not too hot, and after spraying, through the rapid absorption by the leaves at night, the effect takes hold relatively quickly.

Correct use of growth regulator can significantly improve the stalk-breaking resistance of corn, promote plump kernels in the corn ear, and achieve a yield increase. If used improperly, the corn will grow poorly with fewer ears, causing a yield reduction. Regarding the dosage, many farmers cannot grasp it accurately or cannot master the dilution ratio. Here is a small example: for instance, at a 500-fold dilution, that means dissolving 1 g of the agent in 500 ml of water. If you still do not quite understand or are not fully confident, in this respect you can consult the local agricultural technical expert, and try to avoid mistakes as much as possible.

I hope the above information can be helpful to everyone, to avoid problems in production and achieve high and stable yields.
