Visalia, Calif., May 5, 2026 – Sym-Agro Inc. announced it has received EPA registration of CINNEX™ fungicide-insecticide for use on 93 crops across the U.S., except in California where registration is anticipated for the 2027 growing season. Sourced and manufactured in the U.S., CINNEX is a powerful, cost-effective solution that deploys multi-site activity and multiple modes of action to destroy a broad spectrum of diseases and insect pests on contact. It provides the safety profile and tank-mix flexibility needed for effective integrated pest management (IPM) and resistance management programs, is MRL-exempt and can be applied up to the day of harvest.
“We used our 15-plus years of expertise with the cinnamaldehyde active ingredient to create CINNEX right here in the USA. Conventional crop growers deserve the high efficacy, crop safety and IPM compatibility of the cinnamaldehyde active at a value proposition that aligns with their budgets. That’s what we’ve developed in CINNEX. Now conventional crop growers have cost-effective, high-quality, reliable control that addresses their pest management needs throughout the season,” said Peter Bierma, president of Sym-Agro.
The proven cinnamaldehyde active controls a range of key diseases and 85+ insect pests, including powdery mildew, Botrytis, Monilinia, aphids, psyllids and caterpillars, to protect high-value, conventionally grown crops, including grapes, citrus, pome fruit, stone fruit, berries, tree nuts, hops and vegetables. CINNEX features powerful curative and preventative activity, obliterating target diseases and insect pests on contact and resulting in quick knock-down. Belonging to FRAC Group BM03, CINNEX works through multi-site activity and multiple modes of action against in-season, active pathogen life stages to break the sporulation cycle and attack cell walls and membranes, stopping and preventing the spread of fungal infections. Part of IRAC Group UNE, CINNEX uses multi-site activity and multiple modes of action to cause insect dehydration and suffocation that results in juvenile and adult mortality. It also works through ovicidal activity to reduce egg hatch and survivability, minimizing future pest outbreaks.
“CINNEX is an exceptional solution for disease and insect management throughout the season, both as a standalone product and as a tank-mix parter with conventional pesticides. Starting the season with CINNEX stops diseases and insect pests before they build and with minimal impact on crucial beneficial predators, which help manage pests during the season,” Bierma explained. “It targets and disrupts pathogen growth even at low use rates, making it an economical tank-mix partner with conventional fungicides for enhanced disease and resistance management. In addition, CINNEX works synergistically to boost performance of all products in the tank, including sulfur, helping power season-long resistance management while supporting IPM for robust pest control.”
As a biopesticide, CINNEX has an excellent safety profile for crops, beneficial insects, workers and the environment. As an MRL-exempt product, it also delivers peace of mind when marketing to global customers. Backed by 150+ field trials of the cinnamaldehyde active, CINNEX demonstrates a high level of crop safety to foster optimal crop health.
“We are excited to introduce the power of EPA-approved CINNEX to the conventional crop market so growers can realize the benefits of its high efficacy, tank-mix compatibility and safety profile. Our first self-developed EPA-registered pesticide, CINNEX is designed to cost-effectively fit the demands of conventional disease and insect pest control needs,” Bierma stated. “In addition, CINNEX has separate approved labels for use for home and garden, turf and ornamental, post-harvest crop protection, and seed treatment. We are currently exploring the right strategies and partnerships to bring CINNEX to these markets.”
