Abstract

Granular soil-applied pesticides were introduced in 1973 for the control of seedling pests of sugar beet, including the ectoparasitic nematodes that cause Docking disorder. By 1977 most of the area at risk from Docking disorder had been treated, largely with aldicarb; however, despite these treatments, surveys based on an examination of growing crops continued to report large yield losses in years with wet springs. In a field experiment, aldicarb was readily leached following early application in a year with a very wet spring (1983). The distribution of toxic aldicarb residues in soil was simulated for each of the years 1979–1983 using a mathematical model: these simulations suggested that nematode control would be seriously decreased only in exceptionally wet springs. It was concluded that the surveys contain a systematic bias, underestimating damage in earlier years but overestimating damage in recent years when pesticides have been widely used
