Expertise on the signals that affect plant-pathogen interactions has allowed them to screen and select nutrients and active ingredients that ensure plant health and effectively thwart fungal invasion. All Lareki formulations have been awarded ZERYA certification. Within the ZERYA standard, residue-free means that any active ingredient is determined to be below 0.01 ppm when analyzed.
