The biological control simply aims to use naturally occuring enemies to help reduce the invasive plant’s impact on agriculture and environment. Some herbivores and pathogens can be effective biocontrol agents for weeds. Not all weeds are suitable for biological control. The selection of appropriate target weeds is a serious consideration. It can take up to twenty scientist years to reach a successful conclusion. Environmental considerations may restrict future biological control practice because of increased concerns about possible damage to non target native or even agricultural plants. However, biological control has been successfully used against a wide variety of weed types, from a broad taxonomic spectrum, from annual herbs to trees. The diversity of weeds that have been controlled biologically Is a clear indication of a great utility of the method, even it is not possible to predict the outcome of particular projects. Developing a biological control project requires a substantial investment. Considerably host-specifity testing is done prior to the release of biological control agents to ensure they will not pose a threat to non target species such as native and agricultural plants In Europe no classical biological control agent has been released against an invasive weed, but many studies are carried out and future expectations lead in this direction.
