Objectives:
The purpose of this article is to present biological weapon in the process of reducing the structural power of a state. This article answers the following questions: What is the structural power and national economy? What is human capital and agriculture? What is the biological weapon and what is its effectiveness? How does the biological weapon reduce the structural power of a state?

Methods:
Analyzing literature and documents.

Results:
This article states that a biological weapon is a tool for reducing a state’s international potential used by a hostile state. This is the main reason why agriculture is the high-risk target for biological warfare. From the perspective of a biological weapon, a high-risk target as agriculture is human capital that is engaged in the production of goods. This sphere is essential for the national economy as well. The health and vitality of the population is crucial for effective production. All of the above gives the full scope of the country’s capabilities in the international sphere which could lead to becoming a power actor in global politics

Conclusions:
From the perspective of a hostile state, the structural power of the targeted state cannot be reached. At this point, it can be stated that a state's structural power can be limited by reducing its relational power (reduction of international power through reduction of production/agriculture). Due to the wide spectrum of potential biological hazards a biological weapon can easily meet the needs of a hostile state.
