CABI’s range of agricultural mobile apps provides a way for smallholders to access up-to-date, real-time information, either first-hand or through advisory services.

Smallholder farmers across the world need access to agricultural advice so their crops are less susceptible to pests and diseases. Extension and advisory service workers are important for communicating science-based solutions with communities, providing essential information. Their advice on crop health, including pest and disease diagnosis, helps farmers to lose less of what they grow, stimulating agricultural production.

Digital development, such as agricultural mobile apps, can help advisory service workers provide the best possible advice to farmers by giving them access to current, relevant information. Through the PlantwisePlus programme, CABI is developing a Toolkit of digital decision support tools aimed at agricultural extension workers, agro-input dealers and farmers.
