Fusarium oxysporum

banana cultivar, was all but wiped to extinction by a race of fungi dubbed Fusarium Oxysporum sp. cubense race 1, or simply Foc 1 (Hwang and Ko, 2004). The fungus operates by entering via the rhizomes of the banana plant, subsequently…

oxysporum is a ubiquitous and diverse fungal pathogen inhabiting the soil. Notably, it is one of the most important plant pathogen species associated with blights, root rots and wilts. F. oxysporum has a broad host range compared to F. graminearum (Fg) and F. verticillioides (Fv) which predominantly infect cereals. Although they are mainly harmless saprobes, many formae speciales found within the F. oxysporum complex can cause disease. Despite host adaptation and specificity being studied within…

Combined chemical and biological control of Fusarium and nematode species associated with Eldana saccharina in sugarcane Introduction Eldana saccharina Walker (Lepidoptera: Pyralidea) is a serious pest in maize, sorghum and in all sugarcane regions of South Africa. It is an African native with a wide distribution within South Africa and has a number of natural hosts including the water sedges Cyperus dives and Cyperus papyrus (Assefa et al., 2008; Webster et al., 2005; Rutherford, 2015). The…

specificity, efficiency and rapidity under isothermal conditions has been developed in the present study for the rapid detection and diagnosis of M. eumusae from the DNA of pure cultures and single leaf spot tissue. Several authors reported about rapid amplification of many fungal pathogens using LAMP method. For example, Tomlinson et al. (2010) designed LAMP primers based on the intergenic spacer of nuclear ribosomal DNA (rDNA) for detection of Botrytis cinerea. Zhang et al. (2013) designed…

rust (Puccinia arachidis), collar rot (Aspergillus niger van Tieghem), stem rot (Sclerotium rolfsii), root rot (Macrophomina phaseolina), and afla¬ root (Aspergillus flavus) are economically important in India. In addition to these disease nematode disease such as root knot and viral disease peanut bud and stem necrosis, groundnut mottle and clump (Ghewande and Reddy 1986) are major diseases that limit groundnut production and productivity. Pre- and post-harvest aflatoxin contamination in the…

enzymes and phenolic compounds in the tomato plants. It has been observed that co-inoculation of BA, SA and HL increased the level of chitinase and β-1, 3-glucanases in the leaves as well as roots. The level of PO, PPO, PAL and phenolic compounds in tomato leaves and roots were also directly correlated with the disease reduction in glasshouse experiment. The PO and PPO catalyze the biosynthesis of lignin/ other oxidative phenols and lead to accumulation of antioxidants in the leaves playing…
