Fusarium oxysporum f.sp.radicis-licopersici (Forl) is a soilborne pathogenic fungus which can cause tomato foot and root rot (TFRR). Tomato root exudate is a good source of nutrients for both Forl and the TFRR-suppressing biocontrol bacterium Pseudomonas fluorescens strain WCS365. Incubation of Forl microconidia in tomato root exudate stimulates their germination. This phenomenon is observed, t...

In [RS], an explicit orthonormal basis of wavelets forL 2 (IR s ), s = 1; 2; 3, was constructed from a multiresolution approximation given by box splines. In other words, L 2 (IR s ) has the orthogonal decomposition

Fusarium head blight caused by oxysporum f. sp. Radicis-lycopersici (FORL) is a constraint to tomato cultivation in Korhogo, Côte dIvoire. To control this disease, the antifungal activity of essential oils extracted from certain plants was evaluated comparison with that synthetic fungicide for use. In vitro tests were performed on different life stages FORL. The vivo evaluations consisted ca...

Plant growth-promoting rhizobacteria (PGPR) may prevent attack from pathogenic microorganisms by eliciting induced systemic resistance (ISR). In the present work, Pseudomonas putida isolate TR21/1 showed significant biological control of tomato seedlings inoculated with Fusarium oxysporum f.sp. radicis-lycopersici (FORL). Here, SA-responsive genes PR-1, PR-4, PR-6 and CH9 were downregulated upo...

Long path length infrared tunable diode laser absorption spectroscopy is being developed as a technique for monitoring several low energy beta-decay radioisotopes associated with nuclear waste offgases. We will report a determination of sensitivity forl 4co 2 and an evaluation of potential interferences. Recent experiments have also ~~monstrated an applicability for measuring iodine isotopes su...

Monitoring of pathogenic strains of Fusarium oxysporum (Fox), which cause wilt and rots on agricultural and ornamental plants, is important for predicting disease outbreaks. Since both pathogenic and non-pathogenic strains of Fox are ubiquitous and are able to colonize plant roots, detection of Fox DNA in plant material is not the ultimate proof of an ongoing infection which would cause damage ...

This study explored the role of Aphanocladium album (strain MX95), Pleurotus ostreatus ALPO) and eryngii AL142PE) as potential biological limiters. MX95, ALPO AL142PE were screened under laboratory studies against Phytophthora nicotianae (PN), Fusarium oxysporum f. sp. radicis-lycopersici (FORL), lycopersici (FOL), solani (FS), Sclerotinia minor (SM), sclerotiorum (SS), Athelia (Sclerotium) rol...
