Cyromazine (cyromazine, CAS 66215-27-8, IRAC 17) is an insecticide that acts as a molting disruptor in dipterans. This is a product developed by Ciba-Geigy AG (currently Syngenta). Cyromazine does not appear to inhibit the synthesis of chitin or cuticle proteins and its mode of action is unknown (Bel et al., 2000). It has been reported to decrease cuticle extensibility (Reynolds and Blakey, 1989). (https://doi.org/10.1016/B978-0-12-391500-9.00001-2)

In Brazil, the molecule is only used in the insecticide Trigard 750 WP, registered for use against larvae miners (Lyriomyza huidobrensis) in potatoes, chrysanthemums, beans, snap beans, watermelon, melon, cucumber, ornamental plants and tomatoes.
