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. Advices are based on a set of questions to farmers about farm ecology and conditions, available equipment and weed types. 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.
