To clarify the control effects of Trichoderma hamatum strain MHT1134 on Fusarium wilt in continuous pepper cropping fields and its regulatory effects on soil microecology, the physical and chemical properties, enzyme activities, community structures of soil samples from five field types were analysed. Samples were taken from fields that had been continuously planted for 1, 5, 9 years, and applied the strain MHT1134 for 1 and 2 years. The MHT1134 control effects on pepper wilt after application 1 year and 2 years were 63.03% and 70.21%, respectively. 4 kinds of physical and chemical indexes and 6 kinds of enzyme activities in soil were increased. With the continuous cropping years increased, the microbial abundance and diversity decreasing significantly. The relative abundances of Fusarium, Gibberella increased along with the planting years, but decreased after the MHT11134 application. However, the relative abundances of Trichoderma and Chaetomium significantly increased. Additionally, as the cropping years increased, the soil abundance of Actinobacteria gradually decreased, but it significantly increased from 17.56 to 22.44% after the MHT1134 application. Thus, strain MHT1134 effectively improved the microbial community structure of the soil, and it also positively affected soil quality. A continuous application may improve the control effect.

“…In India, occurrence of Fusarium wilt in bell pepper and chilli has been reported in various parts of country and causes up to 25 per cent losses (Madhukar & Naik, 2004). Naqvi (2004) reported 35 percent wilt incidence in many states of USA and it is also reported that after 30 days of soil infestation, Fusarium oxysporum kills 56% chilli seedlings (Mona et al, 2012). The yield loss due to the disease is known to vary from 10-80 percent worldwide (Loganathan et al, 2013).…”

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 India, Fusarium wilt in chili has been reported in many regions and causes around 25% yield losses (Najar et al, 2006). In the USA (Roberts et al, 2004) recorded a 35% occurrence in various states, and it is also observed that after 30 days of soil infection, Fusarium oxysporum kills 56% of chili seedlings (Ragab et al, 2012). Globally, 10-80% yield reduction has been recorded due to this disease (Loganathan et al, 2013).…”

“…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). Moist soil and high temperatures play an important role in enhancing pathogen and disease development.…”

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.
