Mechanism of action: Potassium diphenylurea sulfonate is a highly active cytokinin plant growth promoter selected from diphenylurea derivatives, which can significantly increase the activity of various enzymes in crops. Improve the synthesis of nucleic acids and proteins in cells, promote the division and elongation of plant cells, and promote the development of roots, leaves and buds, thereby increasing crop yield.
1. Promote seed germination, rapid seedling, homogeneous seedling, and strong seedling.
2. Significant cell division function, promote tiller and root development, and improve root vitality.
3. Enhance photosynthesis, significantly increase chlorophyll content, inhibit leaf aging, and delay crop aging.
4. Enhance crop resistance to disease and damage, cold resistance, drought resistance and other properties, and the stress resistance effect is particularly significant.
