Ce manuel est un guide pratique qui permet l'identification rapide des principaux ravageurs et maladies de la culture du cotonnier, rencontrés dans les régions cotonnières d'Afrique sub-saharienne. La faune utile, qui participe aux équilibres naturels, est également décrite. Certains accidents de culture, d'origine naturelle ou provoqués par une intervention humaine, sont expliqués, lorsqu'ils peuvent être confondus avec des désordres d'origine entomologique ou pathologique (foudre, intoxications par pesticides, déséquilibres nutritionnels, etc.) En revanche, les recommandations en matière de lutte chimique ne figurent pas dans cet ouvrage. De nombreuses illustrations permettent de déterminer la cause des symptômes observés. Ravageurs et maladies sont classés suivant leur ordre d'apparition dans le cycle de développement du cotonnier : levée, phase végétative, reproduction. Des éléments de la biologie des ravageurs et de leurs ennemis naturels, la transmission des maladies, la résistance variétale, les relations entre le système de culture et les problèmes phytosanitaires sont évoqués.

Sustainable Development And Tropical Agri Chains written by Estelle Biénabe and has been published by Springer this book supported file pdf, txt, epub, kindle and other format this book has been release on 2017-02-20 with Technology & Engineering categories.

This book links tropical agri-chain dynamics – with which CIRAD and AFD have been involved for decades – to that of sustainable development. Increased environmental and social concerns urge agri-chain actors and development practitioners to design innovations, and public and private actors to invent regulations in connection with agri-chains to improve sustainability.With a view to contributing towards implementing the Sustainable Development Goals (SDGs), this book examines the different roles of agri-chains: as vectors of development, as spaces of innovation, as objects of evaluation, and as arenas of regulation. It builds upon the findings and experiences of CIRAD and its researchers together with their Southern partners, and of AFD and its officers.Linking agricultural production with the other economic sectors, agri- chains are key spaces where local and global challenges to sustainability meet and where local and global actors experiment interlinked or common solutions.

L'idée même de communiquer en langues africaines avec le paysan africain paraît incongrue, sauf quand il s'agit de lui donner des consignes à exécuter. C'est justement là que gît le problème. En effet, en s'abstenant d'écouter le paysan, car c'est bien ce qui se passe souvent, en réalité, on se prive de toute la connaissance qu'il a pu acquérir dans son domaine d'activité. Lorsque, au contraire, on l'écoute parler dans sa langue, on est obligatoirement amené à recentrer les propos qu'on lui tient, et l'on doit aussi faire l'effort de mettre au point un langage technique mutuellement compréhensible. C'est pour aider à répondre à cet objectif que nous avons conçu cet ouvrage.

The third part covers sustainable and secure food production specifically addressing genetically modified traits in Chapter 6 (James McWilliams) and omega-3 fatty acids in Chapter 7 (Jay Whelan et al.).
