Triprene Explained

Triprene is an insecticide that is no longer in use. It is an insect growth regulator introduced by Zoecon Corporation (now Sandoz AG) under the "Altorick" trademark,^[1] registered 1974 and not renewed, expiring in 1980.^[2] The EPA records no registration, now or past.^[3]

Triprene is nontoxic to mammals, non-carcinogenic, not a human endocrine disruptor, and not neurotoxic. To fish, it may be of moderate toxicity.^[4]

Triprene is a juvenile hormone mimic.^[5] It disrupts insects' development by endocrine disruption, causing incomplete pupation and sterile adult insects.

Effectiveness

Triprene was tested against the similar kinoprene and hydroprene. Kinoprene was the most effective against long tailed mealybug and solanum mealybug, hydroprene and triprene both needing multiple applications. All controlled coffee brown scale.^[6]
