Optic Foliar Evios
Optic Foliar Evios is an oil‑free, odourless foliar pest control formulated from plant‑based extracts to eliminate soft‑bodied insects such as spider mites, whiteflies, thrips, and fungus gnats. Designed to work on contact without leaving residue or affecting flower aroma, Evios delivers rapid knockdown and protection through late bloom while remaining gentle on delicate plant tissues.
Evios integrates easily into IPM programs as a clean, low‑odour option that won’t clog stomata or leave oily films. It mixes clearly, sprays evenly, and rinses clean, helping you keep flowers pristine while suppressing pest pressure across vegetative and flowering stages. For fastest uptake and broader coverage, Evios is commonly paired with a foliar penetrant; however, Evios itself remains flower‑safe and residue‑free when used as directed.
