![]() ![]() Nanostructured materials may have all the crystallites and interface boundaries with the same chemical composition or not, resulting in structures known as nanocomposites. Encapsulation in polymer matrices adds value to the product, which preserves their properties and viability. One of the stragies to overcome this is their encapsulation in order to prevent a fungal matrix. Natarajan Chandrasekaran, in Nano-Biopesticides Today and Future Perspectives, 2019 6.9 Silicate Nanocomposites for Entomopathogensīioinsecticides based on entomopathogenic fungi have been in use for decades now however, conidia produced by these fungi are very sensitive to abiotic factors. ![]() Next generation sequencing (NGS) strategies that evaluate the DNA content of an organism or profile the full range of organisms in a sample, is now being used to screen for beneficial microbial candidates, and to help us understand how biofertilizers interact with the natural microenvironment and present their beneficial abilities.Prabhakar Mishra. The eco-friendly biofertilizers prompt a wide range of applications such as plant growth promoting rhizobacteria (PGPRs), endo- and ectomycorrhizal fungi, and cyanobacteria.īut much remains to be learned to gain the full potential benefit of biofertilizers. ![]() As a consequence, there is an increasing interest in exploring the usability of beneficial microbes as biofertilizers.Īnd with the first promising results, it has become an important aspect in the agricultural sector to develop sustainable farming and crop production. These have been found to cause a serious threat to human health and to the environment. Traditional fertilization strategies are mainly dependent on inorganic chemical-based fertilizers. Plant defense mechanisms include a long list of both physical and chemical barriers, but also a microbial environment on the leaves and roots is of key importance for their defense. To combat these risks, plants have evolved a broad range of tactics to defend themselves. The aim of research into biocontrol strategies and products is to reduce the dependence on chemical products, for the joined benefit of human health and the environment.Ĭrops are vulnerable to environmental challenges such as changing climate with the risk of drought or fluting, and infection with pathogens including types of fungi, nematodes, bacteria and viruses. A number of products are available, but further research is needed to fully understand how to use biocontrol microbes in large-scale farming. Other functions include release of substances with plant growth regulating properties, and production of antibiotics.ĭue to the adverse effects of some chemical pesticides on both human health and the environment, industry and researchers are looking at biological control microbes as alternatives to traditional pesticides for the management of pests.īiological control of plant pests and pathogens is proving very useful for low cost, eco-friendly and sustainable approaches for defending plants and crops from disease and infection.īiocontrol microbes are increasingly accepted as important means for control of plant diseases in sustainable agriculture. The natural microflora of soil comprises a range of useful bacteria and fungi including the arbuscular mycorrhiza fungi (AMF) called plant growth promoting rhizobacteria (PGPR).Ī healthy soil micro-environment is important for a range of functions: keep the soil rich in nutrients, transforming nutrients into plant available compounds and protecting the soil and plants from infection and disease.Ī key part of this ability comes from the ability of the microbes to increase the amount of fertilizer that is taken up by plants: they increase the nutrient use efficiency of fertilizers, and make the nutrients bound in organic material available to crops through biodegradation of organic matter.
