“…Nitrogen content of the waste materials added to FOP in composting mixture can consistently affect the nematode suppressiveness of compost, as improved or limited by the combination with high or low-nitrogen wastes, respectively (Oka & Yermiyahu, 2002;Nico et al, 2004). This synergism of nitrogenous materials with FOP wastes could be attributed to the enhancement of both nematicidal mechanisms above described for compost soil amendments (Raviv et al, 2005). Our experiment is the first report of the suppressive activity of a mushroom substrate-based compost, as C 3 , on RKN, as it was previously stated against Pratylenchus penetrans on potato and various trichodorid nematode species on ornamental bulb crops (LaMondia et al, 1999;Zoon et al, 2002).…”

278 SummarySuppressiveness of soil amendments with different rates of composted biowaste materials, olive pomace, municipal green wastes, sewage sludge and spent mushroom substrate, was evaluated against the root-knot nematode Meloidogyne incognita on tomato in potting mixtures. Soil amendments were applied at 0, 10, 25, 50 and 100 g kg -1 soil, according to a randomized block design with five replications for each treatment. Sixty days after tomato transplanting, nematode population density on plant roots and in soil and root gall infestation were assessed on each root system, and plant top and root weight were also recorded. Soil pH, dry and organic matter content, total and ammoniacal nitrogen were analyzed at the same time. Olive pomace-based composts resulted in the highest nematode suppression (73 -97 %, according to the rate) and significantly reduced gall formation on tomato roots. Olive-waste compost affected positively tomato growth only in combination with sheep wool wastes, but it caused phytotoxicity when mixed with chicken manure and urea. Soil amendments with composted mushroom substrate also provided a consistent nematode suppression and a significant increase of plant growth, whereas composted municipal green wastes were more suppressive and positively affected tomato growth when combined with sewage sludge. Soil chemical parameters were scarcely affected by compost amendments, as organic matter was significantly increased only by the olive pomacederived composts and nitrogen content only at the highest rate of the five composts. Data from the experiment confirmed the potential of compost amendments for sustainable management of root-knot nematodes both in field and greenhouse container media, though their technical effectiveness and economic convenience are strictly dependent on a correct proportion and local availability of raw materials used in the composting process.

“…Depending on the type of organic amendment and compost, multiple studies have reported a major or moderate suppressive effect of compost or compost tea on diseases such as bacterial spot (Xanthomonas vesicatoria), early blight (Alternaria solani), bacterial canker (Clavibacter michiganensis), corky root rot (Pyrenochaeta lycopersici), gray mould (B. cinerea), F. oxysporum, P. infestans, P. ultimum, R. solani, and Verticillium dahliae, as well as on nematodes (Meloidogyne javanica) (Al-Dahmani et al 2003;Cheuk et al 2005;Noble and Coventry 2005;Raviv et al 2005;Haggag and Saber 2007;Hasna et al 2007;Yogev et al 2009;Koné et al 2010;Lopes et al 2011;Yogev et al 2011;Dionne et al 2012). The microbial content, nutrients, and organic molecules such as humic or phenolic compounds in compost and compost tea have been shown to be the main factors in the inhibition or prevention of plant disease.…”

“…radicis-lycopersici et qui présentent un système racinaire vigoureux et une meilleure croissance végétative. Certains d'entre eux ont obtenu, par contre, des résultats positifs contre F. oxysporum en additionnant des composts de différentes sources (Cotxarrera et al, 2002 ;Kavroulakis et al, 2005 ;Raviv et al, 2005). Ils ont attribué cet effet, au moins partiellement, à l'activité antagoniste de la microflore du compost dont la composition et les profiles physiologiques diffèrent de ceux de la microflore de la tourbe (Tuitert et al, 1998 ;Borrero et al, 2006).…”

RESUMEObjectifs : L'utilisation des moyens de lutte biologique contre les agents phytopathogènes a connue un essor considérable durant les deux dernières décades. L'objectif du présent travail est d'étudier l'effet d'un compost de déchets urbains solides, de ses extraits aqueux et de diverses souches de trichoderma harzianum sur la suppression de la verticilliose de la tomate causée par verticillium dahliae. Matériel et méthodes : Des plantules de tomates inoculées par des souches de t. Harzianum, traitées avec le compost ou encore avec l'extrait de compost sont inoculées avec l'isolat p3 de v. Dahliae. Résultats : Nos résultats ont montré que l'amendement du sol avec le compost à un taux de 20% a assuré la meilleure suppression de la verticilliose avec 92,38% de réduction de l'indice de rabougrissement (ir) et 92,41% de réduction de l'indice d'altération foliaire (iaf). Suivi par la fertigation des plantes par les extraits de compost ou leur inoculation par la souche tcomp de t. Harzianum, isolée à partir du compost, qui ont induit des pourcentages similaires de réduction de l'ir et de l'iaf. Alors que les deux autres souches de t. Harzianum ont induit des pourcentages de réduction qui n'ont pas dépassé 81% et 75% pour l'ir et l'iaf, respectivement.La suppression de la verticilliose semble due à la stimulation de la croissance végétale des plantes et aussi à l'inhibition de la pénétration et de la migration du pathogène à travers les tissus vasculaires de la plante. En effet, le traitement des plantes avec le compost, l'extrait ou encore leur inoculation avec la souche tcomp a permis de confiner le pathogène au niveau des racines de 50 à 60% des plantes, alors que les autres traitements ont permis son ascension jusqu'à l'hypocotyle de 70% des plantes inoculées. Les plantes témoins inoculées par le pathogène l'ont hébergé jusqu'à l'épicotyle de 100% des plantes. Conclusion et application de la recherche : le compost étudié constitue un bon amendement en tant que biopesticide contre la verticilliose de la tomate. Cette aptitude suppressive est liée, en partie, à sa population de t. Harzianum mais aussi à des facteurs chimiques. Mots clés : compost, extrait, trichoderma harzianum, verticillium dahliae, verticilliose, tomate. AbstractEffect of compost and trichoderma harzianum on verticillium wilt of greenhouse tomato crop Objectives: the use of biocontrol means against plant pathogens has grown considerably in two past decades. This work aim to study the effect of municipal solid waste compost, its aqueous extracts and different strains of trichoderma harzianum on the suppression of verticillium wilt of tomato caused by verticillium dahliae. Material and methods: tomato seedlings inoculated with strains of t. Harzianum, treated with compost or even with compost extract were inoculated with v. Dahliae isolate p3. The results: the results showed that soil amendment with compost at a rate of 20% provided the best control of verticillium wilt with a 92.38 % reduction of stunting indice (ir) and 92.41% reduction in the...
