Eggplant (Solanum melongena) is one of the most economically important vegetable crops cultivated and consumed globally. It is predominantly produced in Asia (94%) (Food and Agriculture Organization of the United Nations (2020)). Eggplant production is highly profitable and a ready source of income for small, resourcepoor farmers (Francisco et al., 2012). Eggplant is the most produced vegetable (by volume) in the Philippines, accounting for more than 30% of the country's total vegetable production (PSA (2020)).However, plant pathogens hamper its production by damaging the leaves, stems and roots, thus affecting its marketable fruit yield. The damage can range from 50% to 90% or eventually destroy the whole crop (Palo, 1938), resulting in losses.There are more than 30 pathogens associated with eggplant diseases (Tangonan, 1999), including those causing fruit rots, for example Colletotrichum gloeosporioides f. melongenae (Colletotrichum

“…The sequence of the partial rDNA internal transcribed spacer of the isolated fungus in addition to reference darker until black necrotic spot symptoms are seen. In advanced stages, small dark olive to black drops can be noticed on the spots presenting sporodochia formed by the pathogen (Han et al 2014;Ben et al 2017). In some plants, the centers of the spots can lyse giving a shot hole appearance (Tewari and Skoropad 1977).…”

“…The plant pathogenic fungus Paramyrothecium roridum (Tode) L. Lombard and Crous, formerly known as Myrothecium roridum Tode ex Fries, has a wide host range including over 300 plant species of vegetables, fruits, ornamental plants and field crops (Chase 1983;Fish et al 2012;Lombard et al 2016;Ben et al 2017;Farr and Rossman 2019). It is a soil born fungus which causes diseases to the foliar parts of its host, usually leaf spots and stem lesions in addition to fruit rot in some hosts.…”

Strawberry plants showing symptoms of leaf spots and petiole lesions were collected from El Qalubya governorate, which is one of the most famous areas that extensively grows strawberry in Egypt. The objectives of this study were to isolate and characterize the causal pathogen of the disease. The isolated pathogen was identified as Paramyrothecium roridum (formerly known as Myrothecium roridum) based on its morphological characteristics and sequencing the partial rDNA internal transcribed spacer (ITS). A pathogenicity test using detached leaf assay revealed that P. roridum is a potential pathogen of strawberry. Symptoms started as small necrotic areas which expanded rapidly to macerate whole leaflets and petioles. In advanced stages of infection, dark olive green sporodochia were clearly distinguished on the infected tissues. Six strawberry cultivars showed different levels of susceptibility to P. roridum. Florida was the most resistant cultivar while Beauty, Camarosa, Fortuna and Sweet Charlie were susceptible. Festival showed a moderate level of susceptibility. An in vitro assay on the effect of the liquid culture filtrate of P. roridum on strawberry leaves showed that the filtrate caused damage to tissues and clear necrotic symptoms were developed. High performance liquid chromatograph (HPLC) analysis on the filtrate of 10 day old P. roridum culture revealed the presence of various mycotoxins. The two major toxins detected were 8-alpha-hydroxyroridin H and myrothecin A in addition to other trichothecenes. Data also revealed the capability of P. roridum to produce polygalacturonase (PG) and cellulase (Cx) enzymes in liquid cultures. The activity of PG was found to be significantly correlated with the age of the growth culture. This is the first record of P. roridum on strawberry in Egypt.
