This thesis reviews written scientific literature on plants that cause dermatoses in agricultural workers. From the literature reviewed, it can be concluded that plants causing dermatoses are relatively common in agriculture, as they include a large number of horticultural, ornamental, field, weed and fruit plants, which in horticulture and agronomy are mainly a source of income for farmers and subjects of work with which they are in daily contact. This thesis presents different types of dermatoses and their symptoms. The major plant families are presented, together with their representatives and the bioactive substances that cause dermatoses. Common bioactive substances that cause dermatoses are the phenols furanocoumarins, sesquiterpene lactones and other terpenoids, and calcium oxalate. Dermatoses can occur in a variety of ways, most commonly by direct contact of the plant with the skin, but also after ingestion. Light - UV light - is needed to activate the toxic action of furanocoumarins. The content of irritants and allergens depends on the plant species, organ, tissue and stage of development of the plant. Review has shown that the irritant and allergen content of a plant also depends on environmental factors. Dermatoses can also result from the contact with mechanical plant defence structures such as spines, prickles or trichomes
