Бренд:

Predominately used synthetic chemical fungicides due to their non-degradable nature, entail serious issues to human health and also to the environment. This has also imposed the issue of drug resistant pathogens against traditionally used synthetic chemical fungicides. To combat this issue several in vitro and in vivo research reports have been generated on post-harvest treatment using plant extracts and essential oils to control fungal spoilage and thereby enhancing the self-life of fruits and vegetables. Plant based antifungal components have a target specific effect and are bio-degradable in nature. Thus they are best alternative to these hazardous synthetic chemicals. Biochemically antifungal principles can disrupt the membrane, causing cell leakage, cytoplasmic evacuation and loss of proton motive force (proton gradient including the membrane potential) and thereby results in the fungal growth inhibition. In the present study, essential oils from four Indian plants namely Cymbopogon citrates, Eucalyptus globules, Gaultheria procumbens and Syzygium aromaticum were used to find their potential antifungal activity against eleven important crop destroying fungal strains.

Screening Antifungal Potential of Indian Spices and Aromatic Herbs riddhi patel and yogesh jasrai antifungal essential oils against plant fungal pathogens
Бренд:

Different genera plants produce a wide range of secondary metabolites, aromatic principles and essential oils. These components are bioactive in nature and are used in variety of purposes like as phyto-medicine, preservative, antioxidant, fragrance and flavoring agent. Apart from routine uses, still many plants are not been fully explored and defined for bioactive role of their secondary metabolites. Similarly plant extracts of wide variety of taxa, have been reported to contain antifungal secondary metabolites and thus, natural products can certainly substitute harmful synthetic fungicides for plant disease control. Plants so are reservoir of biologically active compounds that can affect the metabolic activity of pathogens and that way help to combat the pathogen. Present research work is an effort to define the potential antifungal activity of hexane extracts of fifteen Indian commonly used Aromatic herbs and Spice plants against eleven important crop destroying fungal pathogenic strains. The finding of the present investigation also suggests that plants produce compounds or substances which are beneficial for them to survive in nature and in terms of fighting against microbes.

Wheat grains represent the main food resource to over one thousand million human beings of our planet. Wheat grains come in association with the fungi from the time of grain maturity to the time of storage. Fungi in stored grains are the most difficult enemy to be recognized for human, it can’t be seen easily as other pests. The fungal invasion not only reduces the quality of the grain but also some species of moulds can produce highly toxic chemicals known as mycotoxins. There are hundreds of Essential oils (EOs) have antifungal properties, they offer safe alternatives to pesticides. The potential use of EOs in the liquid phase is not ideal because of a need to a large quanty of EOs, consequently the high cost and also the high residue of these oils can be remained on the products, that can have undesirable odor or taste for consumer, for that EOs using in the vapor phase as a fumigant can be an interesting alternative. Depending on the time and storage temperature, EOs can be volatilized or become inactive. Encapsulation can be the answer to these problems by decreasing the evaporation rate of the EOs, promote the ease of handling and extend shelf life.

Бренд:

Plants are the most important part of the cycle of nature. All other life forms are directly or indirectly dependent upon plants. To control or mitigate plant diseases researchers are applying chemical fertilizers and pesticides. Such inputs to agriculture have contributed significantly to the spectacular improvements in crop productivity but at the same time playing a role as a pollutant for environment and human beings. Consequently, some pest management researchers have focused their efforts on developing alternative inputs to synthetic chemicals for controlling pests and diseases. Biological control of plant diseases is a long-term low-cost and non-detrimental to life. The development of biopesticides has been focused as a viable pest control strategy in recent years. Plant exudates, essential oils and extracts have potential antifungal activity against a wide range of fungi.Various kinds of alkaloids have been isolated from the leaves of A. scholaris. The present study was, therefore, carried out to explore the antifungal potential of organic solvent extracts of bark and leaves of Alstonia scholaris against one of the most phytopathogenic fungi Fusarium solani.
