RiceAdvice-WeedManager

Smallholder rice farmers in Africa often have poor access to information and rely on public or private service-providers - like extension services - for advices on possible alternative weed management strategies. Efficacy of extension services in Africa however, is constrained by sub-optimal training and restricted access to adequate information on weed management. RiceAdvice-WeedManager, developed by AfricaRice and Co-Capacity and ready for testing under field conditions, is an application for Android based smartphones and e-tablets that addresses this status quo. 

WeedManager assists service-providers in generating farm-specific advices for weed management to smallholder rice farmers, before, during and after the main rice-cropping season. WeedManager stimulates implementation of targeted and integrated weed management practices by smallholder rice farmers in Africa - reducing reliance on hand weeding - and thereby contributing to sustainable and affordable productivity enhancement leading to food security and income generation.

The current version of WeedManager will be out-scaled in the coming years with farmers under rain-fed upland and rain-fed and irrigated lowland conditions, starting in Nigeria and Tanzania (CARI network). Impact will be studied and outcomes will be communicated.
