PRODUCT INTRODUCTION
description
Mepiquat chloride is a quaternary ammonium salt consisting of equimolar amounts of mepiquat cations and chloride anions. A plant growth regulator, it is used in agriculture to reduce vegetative growth including sprout suppression in garlic, leeks and onions. It has a role as a plant growth retardant and an agrochemical. It is a quaternary ammonium salt and a chloride salt. It contains a mepiquat.
