Zoëcon, a leader in the pest control industry, continues its commitment to innovation today—since its founders invented insect growth regulator (IGR) technology. Learn more about the storied past that has built the comprehensive Zoëcon® Professional Product lineup.
Zoëcon was founded by Dr. Carl Djerassi, where his team discovered a group of molecules called Insect Growth Regulators (IGRs) that revolutionized insect control by introducing a method that interferes with the development and reproduction of insects. Beginning with methoprene, and the later discovery of hydroprene and kinoprene in the years to follow, these compounds became the building blocks of the comprehensive Zoëcon® portfolio of insect control solutions.
Zoëcon acquires Dallas-based Thuron Industries, an established player in the large animal and companion animal markets. The acquisition provided avenues to develop and produce new IGR products, including what would become the Precor® lineup of flea control products. The partnership also allowed Zoëcon to capitalize on its pheromone research, reformulating Thuron’s Golden Malrin® fly bait to include a pheromone attractant, one of the first such combination products released.
Zoëcon receives approval for the first ever application of an IGR as a crop protectant, against cigarette beetles in stored tobacco—setting a precedent for this insect control technology to be used in new and diverse markets. This paved the way for the successful Diacon® IGR line of stored commodity protectants.
Zoëcon is bought by Sandoz, Ltd., resulting in greater research funding and a substantial expansion of the Zoëcon research department. This helped lead to the development of the IGR hydroprene which passed EPA requirements in 1983, a more effective solution to roach control that powers the current Gentrol® line of products.
In completing the merger with Ciba-Geigy, Sandoz sold its animal health and professional pest control product business, including Zoëcon, to Central Garden & Pet. The division featuring insect control products was first renamed as Wellmark International, then Central Life Sciences, now a business unit of Central Garden & Pet.
The acquisition of Envincio, manufacturers of the popular Essentria® and EcoPCO® products, added a robust lineup of natural and botanical insecticides and active ingredients to the Zoëcon® Professional Products portfolio, creating the industry’s most comprehensive line of insect control solutions.
