Additional information which was not included, but referred to, in the FAO Desert Locust Guideline VI. Safety and Environmental Precautions is provided here. This page will be updated whenever new information on risk reduction of locust control becomes available.
Pesticide Referee Group
The Pesticide Referee Group (PRG) advises FAO on application rates of insecticides used in locust control and on the potential environmental risk of these products.
Studies on environmental and human health effects of locust control
A considerable body of publications is now available on the environmental impact of locust and grasshopper control. These publications provide much data on the side-effects of individual insecticides used in locust control. In addition, information can be found on sampling methods, monitoring approaches and study set-up, which can be used for future monitoring or research activities. The most recent annotated bibliography of these studies can be downloaded in PDF or as a Word document in English.
On pages 54-55 of Guideline No. 6, reference is made to necessary minimum withholding or re-entry periods and pre-harvest intervals after locust control operations. FAO is presently studying what advice it can provide to countries that have not (yet) established such withholding periods.
