Aphids, whiteflies and similar pests damage crops, ornamentals and other plants throughout the dormant and growing seasons. Monterey Horticultural Oil RTU is made to target these chewing and sucking pests all without containing a chemical ingredient. It's a natural, oil-based product and can be used on a variety of crops and ornamentals to control insects and their eggs.

How Monterey Horticultural Oil RTU Works

Monterey Horticultural Oil RTU contains the same aliphatic petroleum solvent as Monterey Horticultural Oil in the gallon jug. However, RTU is more convenient, providing the solution in an easy-to-use spray bottle. The oil covers the insects and the eggs, suffocating and killing the pests on the plants. The oil has no color and is colorless, so it only makes the leaves look wet once it's applied. Even better, it won't scorch the leaves in extremely hot weather.

Where to Use Horticultural Oil RTU

Use this OMRI-listed, oil-based insecticide on most outdoor crops and plants. It kills and controls aphids, scales and other damaging insects, such as mites, off citrus trees, vegetable crops and ornamentals. Since it's OMRI listed, it can be used for organic gardening.

Features and Benefits

Monterey Oil RTU controls everything from aphids to whiteflies. One spray directly on the insects covers them completely, killing them on the spot without any chemical ingredients involved. It can be sprayed on the plants in the dormant season to protect them from infestations, as well as in the growing season under direct sunlight. Other benefits include:

  • Natural alternative to chemical sprays
  • OMRI listed for organic use
  • Kills and controls plant-damaging pests
  • Colorless and non-staining
