Description

Composition for repelling harmful birds

The present invention relates to a composition for combating harmful algae.

Wild birds, which have coexisted with humans for a long time, have undergone significant changes in their habitats as human civilization has developed and urbanization and industrialization have progressed. It adapts well to changes in the environment, and its population is increasing.

The damage caused by algae, which was insignificant or hardly a problem in the past, is gradually increasing and expanding into a social problem. As an example, damage to crops as well as electric shocks from utility poles, airports, fish farms, beekeeping areas, residential areas and other buildings is increasing.

In particular, pigeons act as a carrier of diseases in the human body, causing corrosion of bridges and damage to cultural properties, and damage by magpies to orchards and crops accounts for a large portion of the total harvest. and property damage of KEPCO Co., Ltd. due to damage accounts for more than 35 billion won annually, and economic damage and potential human damage caused by bird strikes at civil and air force airfields reach a considerable extent. Considering this, the need for effective pest control has been raised.

Algae repellents used to protect crops and facilities from harmful algae are largely classified into primary and secondary algae repellents. The primary algae repellent is an agent that immediately prevents birds from approaching by sight, taste, smell, and touch, and has a feature that does not require a learning effect.

The secondary algae repellent is an agent that causes pain by ingestion of food, and refers to an agent that prevents ingestion of crops by learning effect. Therefore, secondary algae repellents are substances that exhibit abnormal physiological and metabolic reactions when ingested, and substances that can specifically react only to harmful algae are preferred.

However, most secondary algae repellents are pesticides and chemicals, and have potential problems that can cause environmental pollution and human toxicity due to residues.
