Active ingredient

Sheep fat

Description

Mode of action

Sheep fat used in plant protection products belongs to the class of natural repellents. Its mechanism is based on a specific odor that is perceived by wild ungulates as a warning signal or a predator presence.

Unlike chemical pesticides or fungicides, this substance does not target the biological destruction of pests but acts as a persistent behavioral barrier. The substance is highly resistant to weathering, allowing it to maintain effectiveness over extended periods.

The lipid base ensures the slow release of volatile compounds responsible for the olfactory effect, extending the protection period and reducing the frequency of applications required throughout the season.

Products based on sheep fat are environmentally safe, as the substance is natural and biodegradable. It does not accumulate in the soil and poses no phytotoxic risk to the treated agricultural crops.

The efficacy of sheep fat depends significantly on local environmental factors and the specific behavior of wildlife populations, making it a reliable tool for integrated pest management.

What it targets

The primary use of this substance group is the protection of agricultural crops, young forest stands, and fruit orchards from damage caused by wild ungulates, such as roe deer, red deer, and moose.

These products are effective in preventing animals from browsing the terminal and lateral shoots of woody plants, which is crucial for the survival and development of saplings in forest nurseries.

In field agriculture, sheep fat is applied to prevent trampling and overgrazing by wild animals, which can lead to significant economic losses for farmers, especially near forest borders.

The substance is often used as a preventive measure to protect tree bark during the winter season when alternative food sources are scarce for wild ungulates.

This group of substances is also used to protect private gardens and ornamental landscaping from wildlife damage, ensuring the integrity of decorative plantings.

Rates and timing

Application rates depend on the concentration of the active ingredient and the specific method of application. Typically, the product is applied directly to terminal buds or tree bark using a brush or a specialized sprayer.

Treatments are recommended to be carried out before the periods of peak wildlife activity or prior to the winter season when the risk of plant damage significantly increases.

Proper coverage of the target plant parts is essential to ensure efficacy. In cases of heavy precipitation or rapid new growth, reapplication may be necessary to maintain the protective odor barrier.

Agronomists recommend starting protection before animals establish feeding habits on a particular plot, as it is easier to prevent browsing behavior than to stop it once it has begun.

Combining lipid-based repellents with other physical barriers or visual deterrents often results in a stronger and more long-lasting protective effect against herbivorous animals.

Restrictions

Despite its high effectiveness, sheep fat has limitations. During periods of extreme food scarcity, when the animal population exceeds the natural capacity of the land, even strong repellents may be overcome.

Application should ideally occur at temperatures above freezing to ensure proper adhesion of the fat base to the plant surface, unless otherwise specified by the product manufacturer.

It is important to monitor the thickness of the applied layer to ensure it does not interfere with the natural respiration and physiological processes of the young plants.

Storage of these products requires cool, dark conditions to prevent the rancidity of the fats, which could lead to a loss of the volatile compounds essential for the repellent effect.

A limitation is the need for regular monitoring of the protective layer's integrity following extreme weather events, such as heavy snowfall or wind, to ensure continuous protection.
