Plant growth regulators

Plant growth regulators are regulating substances in living organisms. Attention should be paid to the following four aspects when using them: First, they must be careful not to use medicines to replace fertilizers: that is, they cannot replace fertilizer and other agricultural measures. Even if it is a facilitative regulator, it must be able to exert its effect with sufficient fertilizer and water conditions. The second is not to change the concentration: the crop plant growth agent concentration requirements are more stringent, the concentration is too large, will cause the leaves to become fat and brittle, there will be dry and fall of the deformed leaves, and even the death of the whole plant; the concentration is too small, it can not reach Some effects. The third is to pay attention to timely use: the use of plant growth regulators should be based on its type, climate conditions, duration of drug efficacy and cultivation needs, select the best time to use, so as to avoid unnecessary investment. The fourth is not to mix and use arbitrarily: The mixture of several kinds of plant growth regulators or mixed with other pesticides and chemical fertilizers must be based on a thorough understanding of the enhancement or resistance of mixed pesticides.
