Horticultural Mineral Oil (HMO) is a highly refined petroleum oil used to prevent and control pests and diseases in plants. The oil is commonly used as an insecticide, fungicide, and miticide. Below is a guide to its proper application.
Steps to Use HMO in Agriculture
Choose the Right HMO
Horticultural oils are generally characterized by a narrow distillation range and low phytotoxicity.
Ensure that it is highly refined and labeled clearly for agricultural use.
Oil Mixing
A 1-2% concentration is generally adequate. (10-20 ml of HMO per liter of water)
Always add the oil into the water. Do not add water to the oil-this prevents the oil droplets from dispersing correctly.
Add a spreader-sticker or surfactant if the instructions recommend doing so to improve coverage.
Potent mixes should only be prepared in the amount to be applied immediately because the emulsion is prone to breaking down.
Application Timing
Avoid leaf burn by applying in cool calm weather (early morning, late afternoon).
Avoid use during conditions of extreme heat, drought, or when the plants themselves are under stress.
Do not use if rainfalls are expected within the next 24 hours.
Spraying Method
Use a fine mist sprayer for best results.
Application should be thorough. Ensure spraying hits the pest coverings on leaf undersides.
Avoid heavy spraying as it would prevent the plant from respiration.
Safety Precautions
Use gloves, goggles, and an appropriate mask. Avoid direct skin products or eye contact.
Keep away pets and children from such areas until it dries completely.
Post-Application Care
Observe the plants for any phytotoxicity symptoms (leaf curling, yellowing).
Repeat as necessary every 7-14 days, depending
Powdery mildew (only when included with other treatments)
