Biopesticides are certain types of pesticides derived from such natural materials as animals, plants, bacteria, and certain minerals. For example, canola oil and baking soda have pesticidal applications and are considered biopesticides. As of April 2016, there are 299 registered biopesticide active ingredients and 1401 active biopesticide product registrations.

Classes of Biopesticides
Biopesticides fall into three major classes:
Biochemical pesticides are naturally occurring substances that control pests by non-toxic mechanisms. Conventional ....etc

The most widely used pesticides utilized for the management of plant-parasitic nematodes
belong to the organophosphorus group. Their efficacy may be reduced in areas where adapted
microorganisms accumulate that are capable of rapidly degrading the active ingredients. The
enhanced biodegradation process of non-fumigant nematicides is of particular concern in
intensive agriculture. However, it remains unclear which microorganisms play the most
important role in the rapid metabolization and how and why this process develops.
Furthermore litt ....etc

Polarization (also polarisation) is a property of waves that can oscillate with more than one orientation. Electromagnetic waves such as light exhibit polarization, as do some other types of wave, such as gravitational waves. Sound waves in a gas or liquid do not exhibit polarization, since the oscillation is always in the direction the wave travels.

In an electromagnetic wave, both the electric field and magnetic field are oscillating but in different directions; by convention the polarization of light refers to the polarization of the elec ....etc

Agriculture is the lynchpin of the Indian economy. Ensuring food security for more than 1 bn Indian population with
diminishing cultivable land resource necessitates use of high yielding variety of seeds, balanced use of fertilizers and
judicious use of quality pesticides. Pesticides are the chemical substances that kill pests like fungi, insects, worms,
and nematodes etc. which cause damage to field crops. The excessive use of pesticides leads to an accumulation of a
huge amount of pesticide residues in the food chain and drinking water en ....etc

Abstract Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every bit of the database. In this paper, we present pCloud, a distributed system that constitutes the first attempt toward practical cPIR. Our approach assumes a disk-based architecture that retrieves one page with a single query. Using a striping technique, we ....etc
