Description:
In the past 50 years, organic pesticides have greatly enhanced the production and quality of food, feed, and fiber as well as the control of disease vectors and pests adversely affecting human health and welfare. n this review of the pesticides literature, the pesticide source term is characterized as it determines the primary and secondary pathways of transport to the soil surface. actors influencing intra- and inter-compartmental transport are defined from a modeling perspective. rinciples of spray physics are discussed, including the influence of application methodology, the influence of formulation on spray propagation, the effects of drift impingement to offsite areas, the metabolic efficacy of formulations in killing pests. lso described are predictive models of the movement of sprayed pesticides.
