The potential of low volume herbicide application in developing agriculture

The removal of weeds by hand is a laborious and time consuming task and a m ajor constraint to the development of small-scale agriculture in many devel oping countries. One solution to these problems in West Africa has been the introduction of low volume spray application of herbicides, particularly w ith CDA (Controlled Droplet Application) sprayers. The successful introduct ion of chemical weed control requires farmer training and support. Recent e xperience in Northern Cameroon has demonstrated how extension services in p lace for cotton development can be utilised to improve cultivation of both cash and food crops through the introduction of appropriate application tec hnologies.
