Monterey® Horticultural Oil - 1gal - OMRI Listed®

Monterey Horticultural Oil 1gal -- OMRI Listed Mineral Oil | Aphids, Mites, Scales & Whiteflies

Monterey Horticultural Oil is a refined mineral oil insecticide (80% mineral oil) that controls soft-bodied insects and mites by coating and suffocating them, blocking the spiracles insects use for respiration. The highly refined formulation is odorless, non-irritating, and designed to be safe on plant tissue -- it will not burn or brown treated plants when used as directed on the MLGNLG6292. OMRI Listed for organic production and labeled for use on ornamentals, roses, vegetables, citrus, fruit trees, and nuts. This 1gal size is the most cost-effective option for larger orchards, greenhouses, or growers applying horticultural oil on a seasonal rotation.

Yes. Monterey Horticultural Oil is labeled for use on vegetables as well as ornamentals, roses, citrus, fruit trees, and nuts. See the product label for specific rates and any crop-specific restrictions.
