Monitoring of incidence and determination of fungi on caraway, fennel, coriander and anise, consideration of disease importance and possibility of chemical protection

Abstract

The incidence of fungi on caraway (Carum carvi L.), fennel (Foeniculum vulgare Mill.), coriander (Coriandrum sativum L.) and anise (Pimpinella anisum L.) was observed on several localities in the Czech Republic. Incidence of 26 parasitic and saprophytic fungi were found on fennel, 35 species on coriander, 21 species on anise and 34 species on caraway. Small plot trials of spices were evaluated during the whole growing season. The fungicides in caraway were applied in different growth stages. The test results showed high effectiveness of autumn and early spring applications on the most dangerous pathogen of caraway – Mycocentrospora acerina. Three fungicides were tested in fennel field trials showing sufficient force against pathogenic fungus Cercosporidium punctum. The complex of root fungi causes the serious damage of coriander. Foliar application of fungicides did not present adequate effect. Four growth regulators were tested, but all of them increased incidence of fungi Fusarium sp. and Alternaria alternata.

Ochraceocephala foeniculi gen. et sp. nov., a new pathogen causing crown rot of fennel in Italy

“…Other fungal species belonging to Leptosphaeriaceae, as well as the closely related Didymellaceae (Odstrčilová et al 2002;Shaker and Alhamadany 2015) have been reported worldwide in fennel crops. In Italy, crown rot of fennel caused by Didymella glomerata (syn.…”

Identification of Curvularia spicifera causing foliage blight on Foeniculum vulgare

“…Several diseases caused by fungi have been reported affecting fennel around the world, including Aureobasidium 2 pullulans, Alternaria spp., Ascochyta phomoides, Cladosporium spp., Botrytis cinerea, Diaporthe angelicae, Didymella glomerata, Didymospora sp., Dendryphion nanum, Colletotrichum gloeosporioides, Epicoccum purpurascens, Erysiphe heracleid, Fusarium spp., Fusoidiella anethi, Itersonilia pastinaceae, Gonatobotrys simplex, Macrophomina phaseolina, Melanconiales sp., Ochraceocephala foeniculi, Leptosphaeria purpurea, Periconia sp., Pythium sulcatum, Phytophthora megasperma, Ramularia foeniculi, Rhizoctonia solani, Sclerotium rolfsii, Sclerotinia spp., Stemphylium botryosum, Subplenodomus apiicola, and Volucrispora sp. (Odstrčilová et al, 2002;Khare et al, 2014;Erberk et al, 2019;Köse, 2019;Aiello et al, 2020). Curvularia species, on the other hand, have not previously been reported to be fennel pathogens.…”

Lytic and Molecular Evidence of the Widespread Coriander Leaf Spot Disease Caused by Alternaria dauci

“…A. dauci (Kuhn) Groves and Skolko) was first defined in Puerto Rico [18] and later reported in some other parts of the world, e.g., Mauritius [19]. In the following 14 years, A. dauci has been reported in many other countries including India [20,21], the United States [22], Algeria [23], and recently in Brazil [24]. Coriander plants and seeds have recently been found to be infected with A. dauci [7,25].…”
