“…In Serbia, phytoplasmas have been found in cereals, vegetables, spices, and medicinal plants [16][17][18][19]. Since the beginning of the XXI century, the carrot (Daucus carota L.) has been considered an important vegetable crop in Serbia, showing a trend of increasing the surfaces on which it is grown over the years.…”

The present study examined the effects of Candidatus Phytoplasma solani infection on antioxidative metabolism in leaves and roots of carrot (Daucus carota L.). Disease symptoms appeared at the end of June in the form of the chlorosis on some of the leaves, which became intensely red one week later, while the previously healthy leaves from the same branch becme chlorotic. A few days later, all leaves from the infected leaf branch were intensely red. Infected plants also had slower growth compared to the healthy ones with fewer leaf branches developed. The roots of infected plants were less developed, seared, or gummy with or without brown-colored root hair. The presence of the pathogen was detected by sequencing the 16S rRNA. National Center for Biotechnology Information (NCBI) BLAST analyses of the obtained sequence revealed 100% identity of tested strain with deposited Ca. Phytoplasma solani strains from various countries and hosts, all belonging to the “stolbur” group (16SrXII-A). Identity of 99.74% was found when the tested Serbian strain (MF503627) was compared with the reference stolbur strain STOL11 (AF248959). The oxidative damage of membranes in carrot cells was accompanied by a decrease in the content of photosynthetic pigments. Furthermore, for the determination of specific scavenging properties of the extracts, in vitro antioxidant assay was performed. In phytoplasma-infected carrot leaves, there was a greater reduction in the level of glutathione content (GSH); however; flavonoids and anthocyanidins seem to be responsible for the accompanied increased antioxidative capacity against hydroxyl radical and hydrogen peroxide.

“…As legal regulations do not allow the application of herbicides, weeds are suppressed either mechanically or thermally (by burning weeds in the inter-row space using a gas burner or infrared radiation). In our country, there are no records on disease types that cause major economic damages (Starović et al, 2015). Some more serious diseases, wilting (the causal agent Verticilium spp.)…”

Organic production of medicinal and aromatic plants is consistent with numerous regulations; hence it is under strict legal control. It implies a production system that does not disturb the naturally consistent balance of ecosystems in which plants are grown, taking into account the preservation of healing properties of derivatives obtained by further processing thereof. This production can be established on virgin lands, or those used for agricultural production but without the application of synthetic chemicals, for a period of at least two years. The main cultivated medicinal and aromatic plants in Serbia are: rosemary, coriander, chamomile, peppermint, lemon balm, valerian, thyme, etc. Weeds are the most serious problem in the organic production system of these plants, while damages caused by diseases are not economically significant. Intercropping in the organic cultivation of medicinal and aromatic plants is the simplest and, at the same time, a very efficient method to reduce the occurrence of pests and diseases, since the use of pesticides is not allowed in the organic production system. Plant cultivation in this system, in relation to continuous cropping, contributes to increased biodiversity, better utilisation of natural resources, higher yields of many plants and reduced abundance of weeds and pests. Moreover, it is very important to emphasise that the effects of intercropping on the quality of an agroecosystem and plants themselves are great, which further leads to a more efficient ability of plants to develop resistance to insects and numerous pathogens.
