“…Spore suspensions were then aseptically filtered through a 100 μm nylon mesh to remove mycelial debris. Inhibition of infection of the seeds by F. verticillioides was studied and evaluated on an 18 point scale using a modification of the method described by Sharma (2011) . The criteria for assignment of scores were as follows: (a) no germination and coat infection – zero point, (b) germinated seed showing coat and radical tip infection – one point, (c) either infected – two points, (d) healthy seed showing germination – three points.…”

Rhamnolipid Biosurfactant against Fusarium verticillioides to Control Stalk and Ear Rot Disease of Maize

Antifungal activity of rhamnolipids (RLs) has been widely studied against many plant pathogenic fungi, but not against Fusarium verticillioides, a major pathogen of maize (Zea mays L.). F. verticillioides causes stalk and ear rot of maize or asymptomatically colonizes the plant and ears resulting in moderate to heavy crop loss throughout the world. F. verticillioides produces fumonisin mycotoxins, reported carcinogens, which makes the contaminated ears unsuitable for consumption. In this study, the RL produced using glucose as sole carbon source was characterized by FTIR and LCMS analyses and its antifungal activity against F. verticillioides was evaluated in vitro on maize stalks and seeds. Further, the effect of RL on the mycelia of F. verticillioides was investigated by scanning electron microscopy which revealed visible damage to the mycelial structure as compared to control samples. In planta, treatment of maize seeds with a RL concentration of 50 mg l-1 resulted in improved biomass and fruiting compared to those of healthy control plants and complete suppression of characteristic disease symptoms and colonization of maize by F. verticillioides. The study highlights the potential of RLs to be used for an effective biocontrol strategy against colonization of maize plant by F. verticillioides.

“…The external symptoms characteristic of Fusarium wilt disease includes vein clearing, leaf epinasty, wilting, chlorosis, necrosis, and abscission leading to complete plant wilting and death (MacHardy and Beckman, 1983). In view of this, the disease incidence in the present study was evaluated in terms of symptomatic leaf infections (Sharma, 2011).…”

“…Pea seeds grown in Wielkopolska and Kujawy were less infected by pathogens (Table 3 and 4). Sharma (2011) reported the presence of Fusarium fungi in seeds in a blotter test. Fusarium fungi were identified on 12.9% of seeds on average.…”

Field pea seeds (cv. Tarchalska) grown in different regions of Poland (Warmia and Mazury, Wielkopolska, Kujawy) were subjected to mycological analyses. Simpson’s dominance index (DI) was used in the study to determine the abundance of each fungal species in the fungal communities isolated from seeds. PCR analyses were carried out with the use of species-specific primers for Fusarium fungi isolated from pea seeds to identify Tri genes responsible for trichothecene synthesis in the growing seasons of 2011, 2012 and 2013.Saprotrophic species predominated on pea seeds cv. Tarchalska grown in various Polish regions, whereas the isolated fungal pathogens were represented by species of the genus Fusarium and Botrytis cinerea. Genes encoding the synthesis of trichothecenes, the mycotoxins produced by Fusarium fungi, were not identified in the PCR analysis. In the group of peas grown in three Polish regions (Warmia and Mazury, Wielkopolska, Kujawy), the highest level of fungal colonization was noted in the pea seeds harvested in Warmia and Mazury.
