Nanopesticide: Future Application of Nanomaterials in Plant Protection

Crop Pests and diseases, and post harvest pests have significant impact on agricultural yield loss  and farmers’ incomes. Farmers mostly use synthetic pesticides to manage pests to maximize crop yields; posing potential risks for workers, consumers and the environments.  Nanopesticides based on metal and essential oils, agrochemical control release formulation hold promise as less toxic pesticide and excellent alternative to conventional pesticide in plant pest and disease control.  Nanoparticles and nanoemulsions of metals, nanoemulsion of essential oils, and matrixs of delivery agents/ carrier in nano pesticide formulations; have been synthesized and their effectiveness assessed against plant pest insect and disease pathogen; and other aspects in plant protection.  This review discuss the main research of nanomaterials that have been  applied and highlights nanoformulation  technologies to be considered for their continuing development of nanopesticides from point of view of  plant protection. 

The chapter has been published in  the book ‘Plant Nanobionics: Volume 2, Approaches in Nanoparticles, Biosynthesis and Toxicity” edited by Dr. Ram Prasad and published by Springer Nature.

Arsenic Contamination in Water

Drinking water may contribute significantly to oral intake in regions where there are high arsenic concentrations in well-water or river-water or mine drainage areas. The concentration in ground water depends on the arsenic content of the bed-rock. Arsenic contamination is spreading fast and entering the food chain through farm products in the region. As people take contaminated water along with contaminated food, the chances of damage become greater. The clinical picture of chronic poisoning with arsenic varies widely. It is usually dominated by changes in the skin and mucous membranes and by neurological, vascular and haematogical lesions. Arsenic and its inorganic compounds have been known to be neurotoxic. The skin is a common critical organ in people exposed to inorganic arsenical compounds. Eczematoid symptoms develop with varying degrees of severity.  Hyperkerotosis, warts and melanosis of the skin are the most commonly observed lesions in chronic exposure. Arsenic contamination in water, vegetables, rice and other foods is spreading as reported in the Indian Parliament. An editorial report was published in the Hindustan Times dated 27th December, 2017.

Inductively Coupled Plasma-Mass Spectrometry : A Rapid Technique for Multi-Elements Determination at the Ultra-Trace Level



Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry which is capable of detecting metals and several non-metals at concentrations as low as one part per trillion. ICP-MS is undoubtedly the fastest growing trace element technique available today. It allows determination of elements with atomic mass ranges 7 to 250. It is able to detect the elements upto part per trillion levels and this ability to carry out rapid multi-elements  determination at the ultra-trace level  have made it very popular in diverse range of applications areas  including environment, geochemical, semiconductor, metallurgical, nuclear, chemical, climatic and biotechnology. In recent years, industrial and biological monitoring has presented major need for metal analysis by ICP-MS. Other uses is in the medical and forensic field, specifically, toxicology and heavy metal poisoning.

Opening Black Box of Soil Microbial Diversity through Molecular Techniques


Biodiversity is generally defined as the variety and variability of living organisms and the ecosystems in which this occurs. The variability of life in the soil encompasses not only plants and animals but also the invertebrates and microorganisms that are interdependent on one another and the higher plants they support. Biodiversity is composed of three interrelated elements: genetic, functional and taxonomic diversity as shown in Figure 1. Taxonomic diversity i.e. the number of species forms an important part of an ecosystem’s diversity and is controlled by the genetic diversity. Genetic diversity can be much more than the number of recognized species. Hence, several species may have the same functions, resulting in functional redundancy. Some species may also interact to perform functions not possible by any single species. Therefore, biodiversity is the interaction of all these elements.

Soil biodiversity is more extensive than any other environment on the globe when all living forms are considered. The soil biota contains representations of all groups of microorganisms, fungi, bacteria, algae and viruses, as well as the microfauna such as protozoa and nematodes. The total diversity is equal to greater than any coral reef or rain forest. Soil algae and protozoa, like higher plants and animals, can be identified by their morphology. Fungi and bacteria, however, require more extensive biochemical and genetic analysis to enable identification.

It has been estimated that only between 1 and 5% of all microorganisms on the earth have been named and classified. A large proportion of these unknown species is thought to reside in the soil. The possible numbers of existing species of different groups are 1.5 million species of fungi, 300,000 species of bacteria, 400,000 species of nematodes and 40,000 species of protozoa. New molecular techniques have been used to estimate that single gram of soil probably contains several thousand bacterial species.
