  • Plant growth regulator compositions, methods of preparation and use thereof
    Patent number: 9609866
    Abstract: Suspension concentrate compositions are disclosed for delivering S-(+)-Abscisic acid either alone or in combination with a second plant growth regulator to crop seed prior to planting as well as for foliar, soil drench, in-furrow and sprench (foliar spray and soil drench) applications are disclosed. The compositions, when properly combined in an aqueous carrier and processed through wet milling to achieve the desired particle size, will result in stable compositions that are desirable for treating crop seeds.
