Abstract
The synthetic plant growth regulator 1,1-dimethylpiperdinium chloride (mepiquat chloride, PIX) has been used worldwide to control plant height in cereals and other crops such as cotton (Gossypium hirsutum L.) over the past 15 years. In cotton, its major effect is to shorten internodes, and the result is a more compact, darker green plant. Its effect on yield has varied from season to season with small decreases as the norm. However, its continued use may still be indicated because of decreased exposure of the crop to insects and enhanced maturity (earliness). During the study period at Mississippi State from 1982 through 1992 on three different varieties, yield was reduced by 6.6 and 17.0% at the low and high application rates, respectively
