Potatoes are Kenya’s second most important food crop after maize, playing a critical role in food security, nutrition, and household income. However, pests and diseases such as late blight, bacterial wilt, aphids, and the potato tuber moth can significantly reduce yields. To address these challenges sustainably, farmers are encouraged to adopt Integrated Pest Management (IPM), a system that combines multiple methods to manage pests effectively while minimizing risks to human health, beneficial organisms, and the environment.

IPM begins with prevention, which includes practices like crop rotation with maize or legumes, planting certified and disease-free seed, selecting resistant varieties, maintaining proper spacing and ridging, keeping the field weed-free, and removing volunteer plants that harbor pests. Monitoring is essential, farmers should walk through their fields regularly, observe pest or disease symptoms early, and keep records of what they see. If pests exceed damage thresholds, chemical control may be necessary, but it should always be the last resort. When using pesticides, farmers must choose the right product, follow label instructions, use proper application techniques, and adhere to pre-harvest and re-entry intervals to ensure food safety.

To use pesticides safely, farmers should always read the label, wear protective clothing (long sleeves, gloves, boots, masks, and goggles), mix chemicals carefully in well-ventilated areas, and spray early in the morning or late in the evening when it’s calm. Pesticides should be stored in their original containers, in locked spaces away from children and animals, and empty containers must be triple-rinsed, punctured, and disposed of safely—never reused. Spraying near rivers, wells, or ponds should be avoided to prevent contamination. IPM not only protects people and the environment but also saves money, reduces chemical resistance, and leads to better yields and quality.
