A Broader Spectrum of Weed Control

Contains clopyralid, the active ingredient used in Stinger® and Reclaim®.

Stigmata is a selective herbicide that delivers excellent season-long control of the annual and perennial broadleaf weeds and woody brush that can infest crops including sugar beets, corn, and barley. It is especially effective on clover, thistle, kudzu, and ragweed but is also formulated to maximize crop safety. Stigmata contains Clopyralid 40.9%, which has been proven to be a fast-acting post-emergent herbicide that has the longevity to potentially reduce or eradicate the next season’s thistle population.

Stigmata is only effective on actively growing weeds and, for best results, should be applied in ideal growing conditions, not during periods of frost or drought. It is tank mix compatible, making it simple to apply with ground equipment or by air (in certain states only). A minimum seven day waiting period is recommended for flood or furrow irrigation, but Stigmata is rainfast in as little as six hours.
