Аннотация: The fungi Colletotrichum coccodes and C. nigrum are dangerous pathogens of potato and tomato crops. In this work, the growth of Calendula officinalis was assessed in laboratory experiments in two types of sterile substrate – poor (sand) and rich in nutrients (“Agrobalt sadovyi”) – inoculated with propagules of these fungi. An uninoculated substrate was used as a control. In both inoculated substrates, damage to the roots of calendula by C. coccodes and C. nigrum and the formation of microsclerotia typical of these fungal species were noted. No symptoms of damage to the above-ground parts of plants were identified.The growth of calendula in the soil was inhibited by both types of fungi. The presence of C. coccodesand C. nigrum propagules did not affect the growth of plants in sand. However, seed germination in thepresence of inoculum of the tested fungi both in sand and in soil occurred faster. This pattern indicates thestimulating effect of secondary metabolites of fungi in the first stages of plant growth and development,and this effect was more pronounced on sand. The susceptibility of calendula to C. coccodes and C.nigrum shows that it can serve as a reserve for infection of these fungi, and therefore it should not be usedas a green manure or intermediate crop in potato and tomato crop rotations with strong development ofanthracnose or black spot in the field.Keywords: Colletotrichum coccodes, Colletotrichum nigrum, phytopathogenic fungi, plant diseases,Calendula officinalis, substrate, green manure culture.
