With a rapid growth invasive alien plants cause a lot of problems not only to indigenous varieties of plants, but also for people, as they are often the cause of many health problems, such as allergies, and they also contribute to greater economic loss. Plant protection is an activity which, on the basis of appropriate scientific knowledge by means of various methods and an economical manner, protects cultivated plants from harmful organisms. In Slovenia, as well as worldwide, the use of pesticides in plant protection programmes is the most widespread method due to price and other benefits. Researchers are looking for new, environmentally more acceptable ways of protecting plants against harmful organisms due to adverse environmental effects of pesticides, their non-target activity, the occurence of resistance to pesticides, and increasingly stringent environmental policies. One such measure is also the study of plant extracts in the suppresing of economically important harmful organisms. In a review article, we focused on the literature review of the usefeulness of plant extracts of several invasive alien plant species in plant protection: knotweeds (Fallopia japonica [Houtt.] Ronse Decr), F. x bohemica (Chrtek & Chrtková) Bailey), goldenrods (Solidago canadensis L., S. gigantea Aiton), stag's-horn sumac (Rhus typhina L.), tree of heaven (Ailanthus altissima [Mill.] Swingle), false indigo (Amorpha fruticosa L.) and stinkwort (Dittrichia graveolens [L.] Greuter), which we are studying within the project ApPLAuSE.
