Pyrabactin is a synthetic sulfonamide that mimics abscisic acid (ABA), a naturally produced stress hormone in plants that helps them cope with drought conditions by inhibiting growth. ABA can be manufactured for agricultural use; however, ABA is light-sensitive and costly to make. Pyrabactin is relatively inexpensive, easy to make, and not sensitive to light. Unlike ABA, pyrabactin activates only a few of the 14 ABA receptors in the plant needed for effective drought tolerance. Its role as an ABA mimic may make pyrabactin an important tool for protecting crops against drought and cold weather.

The discovery of pyrabactin by Sean Cutler was named a breakthrough research of 2009 by Science magazine.
