An overview on common aspects influencing the dissipation pattern of pesticides: a review

Abstract

The common aspects and processes influencing dissipation kinetics of pesticides are determinants of their fate in the environment. Nowadays, with increasing population, the demand for food and fodder crops has also increased. With the development in science and technology, the methods of controlling pests may improve, but the major role played by the environment cannot be altered, i.e. the environmental factors, climatic conditions, and geology of areas under cultivation. Plants play a crucial role in the dissipation kinetics, as they may vary in species and characteristics. Differences in physico-chemical properties, such as formulation, bioavailability, and efficacy of the pesticide, may result in variable dissipation patterns even under the same environmental conditions. While modelling the dissipation kinetics for any specific pesticide applied to any specific crop, each factor must be considered. This review focusses on the variability observed across common factors, i.e. environmental aspects, plant-associated facts, and observed characteristics of chemical substances, influencing pesticide dissipation.
