Bone Oil

Bone oil is a product of the dry distillation of animal bones, classified as a natural organic insecticide and repellent. The substance acts primarily through contact, creating a thin physical film on the surface of insects and plants.

The mechanism of action is based on blocking the respiratory tracts of pests, which leads to their rapid death from asphyxia. In addition, the pungent, specific smell of the composition repels insects, preventing egg-laying on treated surfaces.

The substance does not have systemic action and does not penetrate into plant tissues, making it safe for crop quality traits when used in recommended dosages. It affects only those individuals that come into direct contact with the applied preparation.

It also possesses antiseptic properties, suppressing the development of certain surface fungal infections in orchards and greenhouses. The composition is often used as an adjuvant to improve the adhesion of other active ingredients to leaves.

Due to its oily base, the product adheres to the plant for a long time, providing a prolonged protective effect even during light rainfall.

Bone oil is effectively used against a wide range of soft-bodied pests, including aphids, various mites, scale insects, and young caterpillars. It effectively limits the population density of insects living on leaves and young shoots.

The preparation shows good results in combating whitefly, which often affects greenhouse vegetable and floral crops. The oil disrupts the waxy coating of insects, making them vulnerable to environmental factors.

In horticulture, it is used to protect ornamental trees and berry bushes from a complex of sucking parasites during the growing season. It can also be applied for disinfecting pruning wounds, preventing the entry of secondary infections.

A separate area of application is the use of the preparation as a deterrent against rodents and wild animals that damage tree bark. The high content of fatty acids provides the agent with additional protective functions for the bark.

The main advantage lies in the absence of pest resistance development, as the physical mode of action does not involve the insect nervous system.

Preparation of working solutions requires thorough mixing with water, as the density of bone oil is higher than that of light oils. It is recommended to use emulsifiers to create a stable homogeneous mixture.

Application rates depend on the degree of pest infestation and the type of crop; usually, the solution concentration varies from 1% to 3%. Treatments are carried out by spraying, ensuring full coverage of all vegetative organ surfaces.

Pre-harvest waiting periods are minimal, allowing the product to be used shortly before fruit harvest. However, treatments should be avoided during active flowering periods to prevent disrupting pollinators.

Application frequency is determined by the status of the pest population; the interval between sprayings is typically 7–14 days. In hot weather, the interval is increased to eliminate the risk of phytotoxicity.

The optimal time for application is early morning or evening hours in the absence of direct sunlight to prevent leaf sunscald.

The main limitation is the risk of phytotoxicity if concentration is exceeded or if used in hot, sunny weather. The oily film can cause leaf overheating at temperatures above +25°C.

The agent is not recommended for use on crops with delicate leaves or heavy pubescence, as this may lead to impaired transpiration. A small-scale test on a plant area is necessary before mass application.

The preparation may negatively affect entomophages, so it should be used with caution in integrated pest management systems utilizing beneficial insects. Avoid direct contact with bees during flight.

During storage, it is necessary to monitor temperature conditions, as the product is prone to stratification and consistency changes with temperature fluctuations. Do not allow the agent to enter water bodies due to the risk of creating an oil slick.

The use of personal protective equipment during spraying is mandatory, as the specific smell of the product can cause irritation to the operator's mucous membranes.
