Zuron 150WP is a plant growth regulator. It is uptaken through the roots and moves upward to the stem, branches, and leaves of the plants, inhibiting the synthesis of gibberellin. Zuron 150WP reduces the height of the plant when rice fully blooms without causing lodging. It also increases the number of rice panicles per square meter, the number of grains per panicle, the rate of solid grains, and the yield.
