The use of chemical plant protection products mainly ensures effective protection of vegetables, field crops, perennial crops and ornamental species from soil pests. These products are also a possible source of danger to non-target organisms and residual toxic effects through contaminated soil and plants, and represent a significant financial cost. In light of today's trends of reducing the use of plant protection products and banning certain products, research and application of non-chemical alternatives in pest control is of great importance. Solarization of soil is a non-chemical measure that effectively controls a large number of pathogens, nematodes and weeds in the soil, while initiating changes in physical and chemical properties of the soil and promoting plant growth. Solarization successfully controls many economically harmful species of nematodes of the genera Meloidogyne, Pratylenchus, Xiphinema, species Globodera rostochiensis, Heterodera carotae, Ditylenchus dipsaci. The effectiveness of solarization has been proven in the control of pathogens such as Fusarium spp., Phytophthora spp., Pythium spp., Sclerotium spp., Verticillium spp., causative agents of bacteriosis Agrobacterium spp., Clavibacter michiganensis, Erwinia amylovora so as of annual weeds, while the effectiveness in controlling of perennial species is somewhat lower. The effect of solarization can be enhanced by introducing rapidly degradable organic matter into the soil; plant residues of cultivated crops, manure, olive processing waste or for this purpose sown species of the family Brassicaceae, with watering before placing the foil on the treated surface. The biosolarization method is an effective modification of the solarization, intensively studied and applied in the last decade.
