What agricultural practice involves using specially refined oils for smothering pests on plants?

The use of horticultural oils is specifically designed for the purpose of smothering pests on plants, taking advantage of the oils’ ability to coat and suffocate insects. These oils are refined specifically for agricultural applications and are effective against a variety of pests, including aphids and spider mites. When applied, the oils create a barrier that disrupts the respiratory systems of these pests, leading to their elimination.

Horticultural oils are also valued for their low toxicity to beneficial insects and their minimal environmental impact compared to synthetic pesticides. This practice aligns with integrated pest management strategies, which emphasize the use of less harmful methods for pest control, thus preserving the ecosystem. The refinement process ensures that these oils are safe and effective for agricultural use, a characteristic that distinguishes them from more general oil applications that might not be suitable for plants.

This understanding of horticultural oils underscores their role in sustainable pest management practices, making them a preferred choice among agriculturalists looking to minimize chemical use while effectively managing pest populations.
