Plant growth regulating composition and methods for making and using same

摘要

Water soluble plant growth regulating compositions in granule form and methods for making and using same. The granules comprise an active medium, a carrier medium and optionally a surfactant, wherein the active medium comprises: a gibberellin, a cytokinin, and an auxin. The inventive compositions are shelf stable and may be completely dissolved in water prior to application on a plant or seed. The carrier medium is water-soluble and preferably lactose monohydrate. The gibberellin is selected from GA3, GA4, GA5, GA7 and combinations thereof. The cytokinin is selected from kinetin, 6-BAP, 1-(2-chloropyridin-4-yl)-3-phenylurea (CPPU) and TDZ, the exemplified cytokinin is kinetin. The auxin is selected from 3-indolebutyric acid, 3-indolacetic acid, 1-naphthylacetic acid, 3-indolebutryic acid and salts and esters thereof. The exemplified auxin is indole-3-butyric acid.
