Paclobutrazol is a successful development of the triazole plant growth regulator in the 1980s, is an inhibitor of endogenous gibberellin synthesis. But also improve the activity of indole acetic acid oxidase in rice and reduce the level of endogenous IAA in rice seedlings. Significantly weakened the top growth advantage of rice seedlings, and promote lateral buds (tillers) breeding. Seedling appearance of the performance of dwarf strong tiller, leaf color green Root developed. Anatomical studies have shown that paclobutrazol can increase the number of cells in the roots, leaf sheaths and leaves of the rice plants. Tracer analysis showed that rice seeds, leaves, roots can absorb paclobutrazol. Most of the paclobas absorbed in the leaves remain in the absorption section and rarely migrate outwards.

The low concentration of paclobutrazol increased the photosynthetic efficiency of rice leaves; high concentration inhibited photosynthetic efficiency, increased root respiration intensity, reduced above ground respiration intensity, improved leaf stomatal resistance and reduced leaf transpiration.

The agricultural application value of paclobutrazol is its control effect on crop growth. It has the effects of retarding plant growth, inhibiting stem elongation, shortening internode, promoting plant tillering, promoting flower bud differentiation, increasing plant resistance and improving yield.

This product is suitable for rice, wheat, peanuts, fruit trees, tobacco, rape, soybeans, flowers, lawns for (plant), the use of significant results.
