Increasing use of pesticides threatens the quality of groundwater with contamination. The objective of the study
was to assess the use of integrated pest management (IPM) in reducing the risks of groundwater contamination
in Lake Naivasha basin, Kenya. Interviewer administered questionnaires were used to collect data on types and
quantities of pesticides used; and other methods used to control weeds, pests and plant diseases. The results
showed that 141 pesticides were used in the basin and that 75% of farms were applying pesticides in high
quantities. All the farms were also using IPM where pesticides and other conservative means were applied.
Majority of farms (62.5%) reported average harvest when IPM methods were used. It was concluded that IPM
program around Lake Naivasha is still in its initial stages and in transition from intensive pesticide use. The
risk of groundwater contamination in the lake basin is therefore still high.
