PRODUCT INTRODUCTION
description
Prohexadione-calcium is a calcium salt containing equal numbers of prohexadione(2-) and Ca(2+) ions. A plant growth regulator, it is used as an anti-lodging agent in small-grain cereals. It has a role as a plant growth regulator, an agrochemical and a gibberellin biosynthesis inhibitor. It contains a prohexadione(2-).
