Anti-fungal activity of leaf extracts

In the study "Optimization of total phenolic extraction of Chromolaena odorata leaf for antifungal activity against plant pathogens", microwave-assisted extraction (MAE) variables were optimized for the extraction of the phenolic compounds from Chromolaena odorata (C. odorata) by using a central composite design (CCD) of response surface methodology (RSM).

Anthracnose leaf disease in rubber trees, caused by the attack of Colletotrichum gloeosporioides, have led to the serious decline in natural rubber production. Continuous usage of synthetic fungicide leave the toxic residues that harm the surrounding animals and plants and are not environmentally friendly. It needs a better solution with organic products that are safer, more effective and biodegradable. Piper species could be considered as a source of new natural products with potential antifungal activities.

Now these days, Plant extracts are used to control plant diseases because of their eco-friendly nature and cost effectiveness. The present investigation focuses on the antifungal activity of eight plant extracts determined through in vitro following poisoned food technique. Maximum inhibition of P. infestans was obtained by Salix sp. leaf extract (59.80% reduction) followed by Datura (48.47%). The other tested plant extracts exhibited moderate activity.

This study was conducted to evaluate the effect of crude and different solvent extract of Leaf of Lantana camara, an aggressive invasive weed against plant pathogenic fungi Colletorichum falcatum causing Red rot of sugarcane disease under in vitro conditions. Aqueous crude extract and solvent extracts such as extracts Methanol, Ethyl acetate, Chloroform were tested at 2mg/mL, 4mg/mL and 8mg/mL concentrations. Results revealed that all the 3 solvent extracts showed significant inhibition at higher concentrations when compared to the Standard Fluconazole (15μg/ml).

Extracts of certain plants have been used to control the plant diseases since several years. Here we report in-vitro studies to examine the antifungal activity of aqueous leaf extractsof three plants and neem oil against three post-harvest fungal pathogens viz., Rhizopus arrhizus, Sclerotium rolfsii, Fusarium solani. Among the leaf extracts, Duranta erecta showed maximum antifungal activity against the pathogens, followed by Lasonia inermis, Neem oil, and Cocculus hirsutus. The degree of inhibition increased correspondingly with increasing concentrations of the plant extracts.

Plants synthesize secondary metabolites and some of them as well as their derivatives have antimicrobial activity such as alkaloids, flavonoids, isoflavonoids, tannins, coumarins, glucosides, terpenes and phenolic compounds. An attempt was made to evaluate the in vitro antifungal and biofumigant nature of ten different plants on suppression of mycelial growth of R. solani. Among these plant extracts at a concentration of 12.5%, total inhibition of the pathogen was obtained on PDA incorporated with leaf extracts of cabbage and garlic creeper. The extracts of leaves of sweet potato (37.

Sacred basil (Ocimum sanctum) is contains active ingredients such as alkaloids, enzymes and other inorganic elements. With a view to assess the fungitoxicity of Ocimum sanctum against the fungal pathogens, studies were conducted on the fungitoxicity of Ocimum sanctum against fungal pathogens. It is concluded that all the four forms i.e., crude (10%), powdered (10%), boiled (10%) and ethanol (1%) extract of Ocimum sanctum leaf significantly inhibited the growth of the test fungus viz., Rhizoctonia solani, R. bataticola, Phoma sorghina, Colletotrichum gloeosporioides, Fusarium oxysporum f.sp.
