Preventing Pesticide Leaching
In response to local and national concerns about pesticides in ground water, we completed an interdisciplinary, long-term (5-year) field project investigating the risk of pesticide leaching from intensively managed small fruit crops with high use of soil applied pesticides. Pesticides used in the study were carbofuran, simazine, and metalaxyl.
