“…Causal agent: Fusarium wilt disease, caused by the soil-borne fungus, F. oxysporum f. sp. capsici is the most important disease on hot pepper that reduces growth, fruit yield and quality (Sahi & Khalid, 2007;Wongpia & Lomthaisong, 2010). The pathogen causes vascular wilt on large variety of economically important crops worldwide (Ortoneda et al, 2004).…”

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.

“…In many countries around the world, Fusarium wilt is most often caused by the most economically important species F. oxysporum var. capsici and F. solani [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. In recent years, some researchers have proposed separating the species F. solani from the taxon Fusarium into the taxon Neocosmospora sensu [ 31 ].…”

Fusarium wilt pathogens represent an ongoing threat to pepper production worldwide. This is the first report providing data on the molecular identification of Fusarium fungi that cause wilt in pepper in the southern regions of Russia. Monitoring of the Fusarium infection on pepper was carried out in 2019–2022 in two economically important regions of this culture production: the Krasnodar Krai and Crimea. Based on a phylogenetic analysis of the translation elongation factor (EF1a) and the internal transcribed spacer (ITS), as well as the macro- and micromorphological characteristics of the fungi, the causative agents of Fusarium wilt have been identified. The causative agents identified as representatives of the Fusarium species composition included: F. clavus, F. solani, F. oxysporum, F. verticillioides, F. commune, F. torulosum, and F. sporotrichioides. Depending on the region, the specifics of biodiversity and the ratio of these species in pathocomplexes were noted. In Crimea, wilting could be attributed to all of the identified species; in the Krasnodar Krai, F. verticillioides and F. clavus were found to contribute to wilting. The pathogenicity test showed that the pathogens of pepper wilting in Russia, in addition to the already known F. oxysporum and F. solani, are the species F. clavus and F. verticillioides. This is the first report on the ability of these species to cause Fusarium wilt in pepper cultures. The obtained data will be of practical value for the development of biological control measures for fungi of the genus Fusarium, which cause pepper wilt in areas of industrial production and seed production. In addition, data on species composition and aggressive isolates will be used in a pepper breeding program for resistance to Fusarium wilt.

“…According to Baba et al (2014), in Kashmir Valley the incidence of fusarium wilt was 40% during the fruiting/flowering stage and 6% during transplanting. According to a survey, about 80% of Thailand's chili plant crop losses were attributable to fusarium wilt (Wongpia and Lomthaisong, 2010). In Egypt, Fusarium oxysporum destroyed 56% of chili seedlings after 30 days of its infestation in soil (Ragab et al, 2012).…”

Cotton is a crucial cash crop in Pakistan, playing a pivotal role in the country's economy, agricultural sector, and employment opportunities. Its cultivation spans over 3 million hectares, primarily concentrated in the Punjab and Sindh provinces. Cotton production in Pakistan contributes significantly to the country's foreign exchange earnings, accounting for a substantial portion of its exports However, cotton pest and disease management is always a challenge as their impact change over time. The widespread use of agrochemicals and synthetic pesticides in major field crops poses significant threats to human and animal health, as well as environmental degradation. Use of beneficial microbes for sustainable cotton production can be a natural ally in the field, as they promote the plant growth as well as protect them from disease, insects and pests. They act as a reservoir of beneficial metabolites, enzymes, and nutrients, and they play a crucial role in biological pest control and disease resistance induction. Additionally, PGP rhizobacteria possess bioremediation potential, enabling them to phytoextract and detoxify pollutants and pesticides. Beneficial microorganisms like PGPR hold immense potential to replace and supplement these toxic chemicals, offering promising applications in organic farming and contributing to sustainable agricultural practices. Despite their potential, only a limited number of bio-formulations have been developed using PGPR strains with plant growth promotion, metabolite production, enzyme synthesis, nutrient mobilization, and biocontrol activities. An increasing body of evidence underscores the potential of diverse microorganisms to enhance plant productivity and yield within cropping systems. Unlocking the full benefits of these advantageous microbes requires a profound understanding of their role in promoting growth, specifically in the realms of fertilization and disease control, along with the elucidation of underlying mechanisms. It is imperative to confront challenges associated with the application of plant growth-promoting (PGP) microbes. This review focuses on the application of PGP microbes in the context of cotton production. Given the scarcity of information on beneficial microbes for cotton production, a comprehensive examination of current research becomes crucial, especially given the increasing interest in cotton inoculants, particularly in developing nations. The heightened attention towards PGP applications underscores the importance of advancing sustainable agricultural practices.
