Leaching of Pesticides from Fields with Recorded Pesticide Applications

International Journal of Environmental Analytical Chemistry, 2002
During two winter seasons, 1998/99 and 1999/2000, drainage water was sampled each fortnight from four fields with recorded pesticide application. Water was analysed for a range of pesticides used on the fields. Two of the four fields were equipped with three vertical stainless steel tubes with screens at 1-1.3 m depths.

On the Timing and Application of Pesticides

American Journal of Agricultural Economics, 1973
AbstractThe model developed by J. C. Headley to illustrate the entomologists' concept of the economic threshold is presented and criticized. A two‐variable model directed at the problems of optimal timing and pesticide application as well as optimal pest population level is presented.

Optimized Pesticide Application

Journal of Agricultural Engineering Research, 2000
A deterministic Eulerian model of aerial pesticide application is introduced. Various assumptions allow the model to include transport of aerosol droplets with a continuous size distribution, vapour production, on-target deposition, off-target drift, and to consider interactions with plant canopies.
