Wheat application of paclobutrazol (15% wettable powder), anti-Wang anti-down, to promote tillering ear, grain, weight gain, become high yield cultivation, an important measure for yield bumper, which has been confirmed in recent years practice. However, in a large area of field applications, often mixed with adverse negative effects. Light is not expected to increase production, while causing the cut. The following on the Hong Kong farm farms nearly two years of district trials and field inspections of the application of paclobutrazol negative effects and should be taken to make a summary of the measures taken.
