 Paclobutrazol is a kind of low toxicity plant growth regulator.

1). Strict control of the dosage. Althogh the higher the concentration of paclobutrazol is, the length contorl effect stronger , but the amount of growth will also be declined.

2). The effect of control length and keep tillers will be declined with the increase of seeding rate. The seeding rate of hybrid late rice should not exceed 30kg/acre.

3). After application, flood irrigation and excessive application of nitrogen fertilizer should be avoid.

4). Nitrogen fertilizers or gibberellic acid could be applied in the case of excessive inhibitation of seeding which was casued by high concentration.

5). Paclobutrizol have different effects on different kinds of rice and barley. When being applied, the dosage should be flexible increase and decrease appropriately.

6). After harvest, the plots must be plowed, to prevent inhibitation to the after crops.
