“…Moreover P. tracheiphilus was included in a list of microorganisms that have to be regarded as potential biological weapons as they cause destructive diseases of economically relevant crops [5]. Although lemon is the principal host, other species of citrus and related genera (Fortunella, Poncirus and Severinia) may be infected [6]. In several Mediterranean countries, including Greece, Israel, Italy and Tunisia, severe infections have been sporadically observed, also in commercial orchards of bergamot, citron, sweet oranges, tangerines, mandarins and mandarin hybrids.…”

This chapter deals with major endemic and emerging fungal diseases of citrus as well as with exotic fungal pathogens potentially harmful for citrus industry in the Mediterranean region, with particular emphasis on diseases reported in Italy and Maghreb countries. The aim is to provide an update of both the taxonomy of the causal agents and their ecology based on a molecular approach, as a preliminary step towards developing or upgrading integrated and sustainable disease management strategies. Potential or actual problems related to the intensification of new plantings, introduction of new citrus cultivars and substitution of sour orange with other rootstocks, globalization of commerce and climate changes are discussed. Fungal pathogens causing vascular, foliar, fruit, trunk and root diseases in commercial citrus orchards are reported, including Plenodomus tracheiphilus, Colletotrichum spp., Alternaria spp., Mycosphaerellaceae, Botryosphaeriaceae, Guignardia citricarpa and lignicolous basidiomycetes. Diseases caused by Phytophthora spp. (oomycetes) are also included as these pathogens have many biological, ecological and epidemiological features in common with the true fungi (eumycetes).

Many species of soil-inhabiting fungus Fusarium, cause severe yield loss in many crops. Experiments were conducted in net house condition with complete randomized block design to determine the individual effect of different inoculum levels of root-knot nematode, Meloidogyne incognita, Race-2 and Fusarium oxysporum f sp. lycopersici on plant growth parameters viz., Plant length, fresh and dry weight and number of fruits of tomato var. P21. The experimental results showed that both the pathogens cause significant reduction in plant growth parameters. However, the fungus was not much effective on plant growth parameters in comparison to root-knot nematode. Greatest reduction in plant growth parameters was recorded in plants inoculated with 8000 J 2 /kg soil of Meloidogyne incognita race 2. The threshold level of root-knot nematode was 1000 J 2 /kg soil while threshold level of Fusarium was @ 1 g/kg soil. Inoculum level of Fusarium oxysporum f sp. lycopersici and Meloidogyne incognita race-2 was pathogenic and caused significant reduction at and above 1 g/kg soil and 1000 J 2 /kg soil respectively.

“…Wilt causing pathogens can be managed by cultural, biological, chemical means and by screening of germplasms/lines for resistance (Mamta et al, 2012). It is also reported that effective means of controlling F.oxysporum include: disinfestation of the soil and planting material with fungicidal chemicals, crop rotation with non-hosts of the fungus, or by using resistant cultivars (Jones et al, 1982;Smith et al, 1988). It is observed that application of fungicides is a quick method to manage Fusarium wilt disease but fungicides are not eco-friendly and adversely affected human beings, microorganisms and environment with its toxic residues (Parker et al, 1985) and also, it has been observed that pathogen has developed genetic resistance against the fungicides (Sela-Buurlage et al, 2001).…”

Hot pepper (Capsicum annum L.) is one of the important cash crops to Ethiopian smallholder farmers and an important agricultural commodity which contribute to export earnings. In Ethiopia, this high value crop is constrained by powdery mildew, Phytophthora leaf blight, Fusarium wilt, bacterial leaf spot, bacterial wilt, bacterial soft rot and pepper motile virus. Among this diseases, wilt disease caused by Fusarium oxysporum f.sp. capsici (FOC) is one of the major pathogen that constrained production and productivity of hot pepper in Ethiopia mainly the Central Rift valley. In Ethiopia, hot pepper fusarium wilt is reported in all production regions in different magnitude. The highest wilt incidence due to fusarium is 90% in some Farmers association of Alaba districts in South Nation Nationalities and peoples of Ethiopia. The economic yield losses due to Fusarium wilt has been estimated at 68 to 71%. Infection and disease development in Fusarium wilt is favored by warm soil temperature, low soil moisture, susceptible host, virulent pathogen and 5.0 to 6.0 pH levels; are some of epidemic factors. Fusarium is reproduced by sexually by teleomorphs and asexually by microconidia, macroconidia and chlamydospore. From the Central rift valley of Ethiopia, 49 FOC isolates were identified based on micro and macroscopic characteristics and the isolate having pink colony color, 3-5 septa forming conidia on potato dextrose agar, perform the most pathogenic ability to Mareko Fana Variety. This pathogen has an over wintering stage called chlamydospore which can exist in the soil for more than ten years without the host. Hot pepper fusarium wilt can be managed by host resistance, biological agent, botanicals and fungicide. In Ethiopia, pepper screening for resistant source, in vitro evaluation of bioagents and fungicides were done. In this review attempt has been made to summarize relevant scientific studies on this economically important crop, hot pepper fusarium wilt and associated factors in Ethiopia as well as its different disease management options, challenges and future prospects.
