The plant growth regulator, succinic acid 2,2-dimethylthydrazide (SADH) is registered for use on certain crop plants under the name Alar and for ornamental plants under the name B-Nine. B-Nine is used to reduce stem elongation of chrysanthemums, hydrangeas and bedding petunias, marigolds and zinnias. This chemical is effective in reducing the growth of oleander, but the cost of the required concentration is generally prohibitive for field plantings.
