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.

Lithium-Sulphur Batteries : Precipitation of Lithium Sulphide and Sulphur Nanoparticles

Lithium-sulphur batteries are known as one of the most promising candidates for the next generation of energy storage devices. These batteries have a gravimetric energy density that is five times higher than that of the best lithium-ion batteries currently available. These batteries even work at very low temperatures even down to -50 °C. Moreover, sulphur is inexpensive and eco-friendly.

Macronutrients in Crop Production

When growing crops of any type, it’s important to understand the required inputs in order to receive the desired yields. One of these inputs, arguably the most important and critical one, revolves around nutrient management. All plants have these requirements, whether it be crops grown for biofuels, fruit production, or landscape ornamentals. Each plant needs […]

Single-Particle Inductively Coupled Plasma Mass Spectrometry for Characterization of Engineered Nanoparticles

With the rapid development of nanotechnology, consumer products containing metallic engineered nanoparticles (ENPs) are commonly available in the market. These particles subsequently are released into the environment, and uptake of these materials by human is very likely. Methods for detecting, quantifying, and characterizing these materials in complex matrices are critical for the eventual understanding of their implications to human health and environment. To assess their effect on the body, reliable and fast detection of these nanoparticles in very low amount becomes increasingly important. Single-particle ICP-MS has emerged (spICP-MS) as a useful tool for characterization of metal-containing nanoparticles. This technique is reliable and fast for counting and sizing particles at lowest concentrations while simultaneously distinguishing between dissolved and particulate analytes.

The chapter describing about this technique has been published in the book “Microbial Nanobionics” volume 2 Basic Research and Applications edited by  Dr. Ram Prasad.

Artificial Intelligence-driven Technologies in Agriculture

Soil degradation, lack of assured irrigation, overuse/misuse fertilizer and pesticides, availability of capital for farmers, inadequate demand prediction, unorganized and low-tech practices are some of the current challenges prevalent in the agricultural sector which can greatly benefit from Artificial intelligence -driven intelligent solutions that enable smarter production, processing, storage, distribution and consumptions of farm products. Timely and site-specific data about crops facilitates the application of appropriate inputs on chemicals and fertilizers, crop health and disease, spreads, monitoring health of farm animals, and intelligent farm mechanization through autonomous machines. Artificial intelligence comes as a great boon to the agricultural sector which is slowly but surely making its presence in agricultural sector. Artificial intelligence-based technologies applications in agriculture are used by various companies. This article has been prepared to make it as informative as possible with some details of companies involved in application of Artificial intelligence-driven techniques and tools employed in agriculture sector.

Toxic Heavy Metals such as Lead (Pb) and Arsenic (As) found in packaged fruit juices

heavymetals

Consumer reports tested forty five popular fruit juices including grape, apple, pear which are sold across North America. As per the report almost half of the tested packaged fruit juices contained potentially harmful levels of toxic heavy metals such as arsenic, lead and cadmium.  Heavy metals are naturally found in the environment but much of the heavy metals soil or water that has been contaminated through mining, pollution or pesticides. Persistent exposure to these toxic heavy metals can have long standing effect on neurological systems, respiratory systems, immune systems particularly in the early development of children. Heavy metals can also put children at risk for diabetes, skin disease, cancer, and behavioral problems. According to James Dickerson, Consumer Reports’ Chief Scientific Officer, some of the juices were marketed for children.
