Pesticide - Wikipedia

Pesticide use raises a number of environmental concerns.Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, including non-target species, air, water and soil. Pesticide drift occurs when pesticides suspended in the air as particles are carried by wind to other areas, potentially contaminating them.

The Evolution of Chemical Pesticides - Fisher Sci

The earliest documented chemical pesticide compounds were elements such as sulfur, heavy metals and salt. The use of elemental compounds for pest control started at the dawn of agriculture and has continued, in some cases, through the present day. Elemental sulfur is believed to be one of the earliest chemical pesticides.

Surfactant - Wikipedia

Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, or dispersants.. The word "surfactant" is a blend of surface-active agent, coined c. 1950.. Agents that increase surface tension are "surface active" in ...

Bio-Pesticides Types: Bio-Herbicides and Bio-Insecticides

ADVERTISEMENTS: Bio-pesticides Types: Bio-Herbicides and Bio-Insecticides! Bio-pesticides are those biological agents that are used for control of weeds, insects and pathogens. The micro-organisms used as bio-pesticides are viruses, bacteria, protozoa, fungi and mites. Some of the bio-pesticides are being used on a commercial scale.

Substrate - Definition and Examples | Biology Dictionary

Apr 28, 2017·Substrate Definition. A substrate is a molecule acted upon by an enzyme. A substrate is loaded into the active site of the enzyme, or the place that allows weak bonds to be formed between the two molecules. An enzyme substrate complex is formed, and the forces exerted on the substrate by the enzyme cause it to react, and become the product of the intended reaction.
