Abstract

Invasions of adventive weed species are one of the leading factors in the transformation of agrobiocenoses and urban cenoses. Naturalization of new species leads to serious ecological, social and economic consequences. One of the dangerous invasive plants is ragweed (Ambrosia artemisiifolia L.), which is widespread in many countries of the world, including Russia. This weed plant causes significant economic damage and harmful impact on human health, since its pollen is a strong allergen. Modern technologies of agricultural production do not always give positive results in the fight against this plant. Therefore, it is necessary to develop new ecologically low-hazard methods to control it, aimed at reducing the productivity of pollen and seeds in order to reduce allergic diseases among people and limit the expansion of its range.

Highlights

A large number of publications by domestic and foreign authors are devoted to biological invasions
The spread of adventive species in the world causes a global threat to modern biogeocenoses and is the most important problem in modern biology
Strong violations of the structural and functional organization are caused by adventive species in agroecosystems, since, having a sufficient breadth of adaptive potential, they are actively introduced into plant communities disturbed by soil cultivation

Summary

Introduction

A large number of publications by domestic and foreign authors are devoted to biological invasions. Adventive species form "biological pollution", this term refers to their reproduction in new conditions [8], which negatively affects species diversity, stability and functioning of ecosystems [9]. Strong violations of the structural and functional organization are caused by adventive species in agroecosystems, since, having a sufficient breadth of adaptive potential, they are actively introduced into plant communities disturbed by soil cultivation. This affects the phytosanitary state of agroecosystems and leads to serious environmental, social and economic consequences. It is known that crop yield losses caused by adventive species amount up to 9-19% in the world and amount up to billions of dollars annually [11]
