“…Hansen, a soil-inhabitant fungus was first described by Massee (1895) in England. This wilt-inducing fungus is a major devastating factor in tomato cultivation worldwide (McGovern 2015). Tomato is ranked second amongst the economic important vegetable crops worldwide, with an annual production of 164 million tonnes from 4.73 million hectares of area under cultivation in 2013 (FAOSTAT 2015).…”

Potential of Fusarium wilt-inducing chlamydospores, in vitro behaviour in root exudates and physiology of tomato in biochar and compost amended soil

Background and aims Biochars are recognised for their ability to improve soil functions and to stimulate plant defense mechanisms. We evaluated the response of Fusarium oxysporum f. sp. lycopersici chlamydospores to tomato plants grown in biochar and compost amended soil to get a deeper insight into the tomato-Fusarium pathosystem. Methods Wood chips and green waste biochar in combination with compost ('WCB comp and GWB comp ' respectively) were studied for their ability to suppress the Fusarium chlamydospores infectivity. Plant growth parameters and in vitro effects on chlamydospores were determined. Results The 'GWB comp ' soil amendment stimulated plants growth and gaseous exchange rates and had a suppressive effect on the chlamydospore infectivity in comparison with the 'WCB comp ' treatment and the treatment containing compost only. The germination rate of chlamydospores was unaffected by the source of root exudates, whereas the mycelial growth was significantly higher in root exudates from chlamydospore inoculated plants grown in 'WCB comp ' amended soil unlike to 'GWB comp ' amended soil. Conclusion Overall, our findings indicate that both biochars had a variable effect on chlamydospores. We conclude that soil amendment with garden waste biochar and compost exhibit a great potential in suppressing Fusarium chlamydospore infectivity and alleviating pathogen-induced physiological stress in tomato plants.

“…As disease incidence and yield losses due to Fusarium induced-wilt are increasing in both open-field and greenhouse production, it is important to develop promising disease management strategies (McGovern 2015). Chemical control of wilt diseases is neither satisfactory nor environment-friendly (Fravel et al 2003).…”

“…Una buena estrategia de control de la enfermedad, es el uso de variedades resistentes y el uso de injertos (Carrillo-Fasio et al, 2003). Sin embargo, el control de esta enfermedad depende principalmente del control químico (McGovern, 2015), existiendo reportes que después que el hongo penetra al tejido vegetal, el control químico resulta sin efecto (Apodaca et al, 2002). Un método to tomato plants mediated by an increase in the endogenous concentration of AS and AJ.…”

“…A good strategy for controlling the disease is to use resistant varieties and grafting (Carrillo-Fasio et al, 2003). However, this disease is controlled mainly by chemical fungicides (McGovern, 2015), but it has been reported that once the fungus penetrates the plant tissue, chemical control becomes ineffective (Apodaca et al, 2002). A method that could potentially reduce Forl disease severity is to induce plant resistance to the pathogen (Ojha and Chatterjee, 2012).…”

Resumen. Se evaluó un extracto de ajo (EA) para inducir la defensa de plantas de tomate contra Fusarium oxysporum radicis-lycopersici (Forl), mediante el incremento de la concentración endógena de ácido salicílico (AS) y ácido jasmónico (AJ). La aspersión de 1 y 2 % del EA sobre plantas intencionalmente infectadas con 1x10 7 esporas mL -1 de Forl, redujeron en 73.53% la severidad de la enfermedad producida por Forl respecto al control infectado. La altura fue similar (p≤0.05) en plantas tratadas con EA y no-tratadas. Abstract. A garlic extract (EA) was evaluated to induce the defense of tomato plants againstFusarium oxysporum radicis-lycopersici (Forl), by increasing the endogenous concentration of salicylic acid (AS) and jasmonic acid (AJ). Spraying 1 and 2% of EA on plants intentionally infected with 1x10 7 spores.mL -1 of Forl reduced in 73.53% the severity of the disease produced by Forl with respect to the infected control. The height was similar (p≤0.05) in plants treated with EA and untreated. The accumulation of AS in plants spayed with 1 and 2% of EA presented two significant increases (p≤0.05), in the second and fifth weeks after spraying, with higher concentrations than the infected and non-infected controls in 11 and 6 times for the first and 2.7 times and 3.8 times for the second, respectively. The AJ was induced from the first week after the treatments, increasing 2.5 and 1.8 times more than the infected and non-infected controls, maintaining those values throughout the evaluation. The results show that the EA reduced the development of the disease caused by Forl Publicación en línea, septiembre 2018 395Fully Bilingual Revista Mexicana de FITOPATOLOGÍA Mexican Journal of Phytopathology
