Many compounds are being introduced into the agricultural environment as a result of fruit and vegetable cultivation and these compounds affect both the environment and food quality. Copper compounds are still irreplaceable in plant protection, which can be confirmed by their use for over 200 years. Since the environment is becoming increasingly polluted and threatening to the human health, the producers strive to adapt food cultivation to situations, where the use of plant protection products and fertilizers is minimized. Since the 1920 it has been indicated that copper affects many physiological functions in the plant; the electron transport in photosynthesis and respiration, which is associated with lipid peroxidation of the thylacoide membranes, moreover it alters the metabolism of proteins and carbohydrates, the synthesis of photosynthetic pigments in the metabolism of phenolic compounds and also affects lignification. Large quantities of copper in the soil are often toxic to plants as they reduce its optimal growth and development and also affects the yield and food quality.

COBISS.SI-ID: 6979961The chapter systematically presents research activities of both authors in the period 2004-2011, related to entomopathogenic nematodes, which are important natural predators of insect pests. The first laboratory experiments with alien entomopathogenic nematodes are presented in detail and the novel determination of five new nematode species in situ in Slovenia is stated. Also, field trials are described, where the efficiency of entomopathogenic nematodes was confirmed under natural conditions and presents their importance in the protection against insect pests. This led to their implementation in the food production systems in Slovenia.

COBISS.SI-ID: 6944889The textbook Principles of Horticulture is designed for students of higher professional studies Agriculture - agronomy and horticulture. The purpose of the textbook was to present basic knowledge from the field of horticulture (fruit growing, viticulture, ornamental plants and vegetable production), which are needed for optimization of the pedagogical process. The textbook consists of three parts. The first part informs the students with the principles of fruit growing, in the second part on the principles of winegrowing and in the third part on the principles of gardening, which includes ornamental plants and vegetables. The students attain knowledge on plant parts of grapevine, fruit plants, vegetables, and different production methods and growth and development of horticultural crops during the year and in different seasons.
