Pesticides are seen as useful inputs to control pests in farming. But, also, pesticides are harmful to human life, animals and the environment. In 1985, Kenya government started Pest Control Products Board to control importation, exportation, distribution, safe disposal and use of pest control products. Dr Esther Kimani, chief executive officer, Pest Control Products Board, says farmers must only use registered products and as guided by their manufacturers.


Water Tower: United Nations Environment Programme (UNEP) says misuse or overuse of chemical pesticides leads to pollution and the deterioration of soil health. What’s your opinion?

Dr Esther Kimani: Pesticides are inherently hazardous, harmful to man, the environment, and animals and that’s why their access and use is regulated. Farmers should only use registered products and as per the label. Before registering products, PCPB [Pest Control Products Board] conducts risk assessment and mitigation measures are prescribed.

UNEP has asked governments to help farmers use biological pest control instead of artificial pesticides. What’s your view?

The board has continued to encourage the agrochemical industry to register biological pest control products. The board has developed guidelines for registration of biologicals, and they are available on our website. The board has assessed, evaluated, and recommended for registration many biological pests control products. The board through awareness creation encourages farmers to use biological pest control products.
