Soya oil

Soya oil (Glycine max oil) is a plant-based substance utilized in agriculture as both an adjuvant and a direct-action contact insecticide. Recognized for its low environmental impact, it serves as an excellent tool for integrated pest management programs, helping to reduce the reliance on synthetic chemical insecticides.

The mechanism of action of soya oil is primarily physical rather than biochemical. Once applied to the plant surface, the oil coats the insects and mites, obstructing their spiracles and causing death by suffocation. Furthermore, the oil disrupts the integrity of the waxy cuticle of the pests, which leads to rapid dehydration and interference with their physiological processes.

The product is effective against a variety of sap-sucking pests, including aphids, whiteflies, scale insects, spider mites, and mealybugs, when used on vegetables, fruit trees, and ornamental plants. When used as an adjuvant, it improves the spreading and penetration of pesticides, ensuring that the active ingredients reach their target effectively.

Application practices require thorough coverage of the entire plant, with particular attention to the undersides of leaves where pests tend to congregate. It is advisable to avoid application during extreme heat or periods of high sunlight intensity, as this significantly increases the risk of phytotoxic reactions on sensitive foliage.

Safety precautions emphasize strictly adhering to the recommended concentration rates, as oil-based products can cause leaf burn if applied at excessive doses. It is crucial to avoid tank-mixing with sulfur-containing compounds to prevent plant damage. Always store the product in a cool, dry place and utilize appropriate personal protective equipment during handling.
