Behavior of pesticides in rice-based agroecosystems : a review / P.A. Roger

Public ISBD Accompagne Impact of pesticides on farmer health and the rice environment / Prabhu L. Pingali Titre : Behavior of pesticides in rice-based agroecosystems : a review Type de document : texte imprimé Auteurs : P.A. Roger, Auteur ; S.I. Bhuiyan, Auteur Importance : p 111-148 Langues : Anglais (eng) Catégories : SCIENCES AGRICOLES Mots-clés : SYSTEME AGRICOLE  RIZ  EFFET DES PESTICIDES  PRODUIT CHIMIQUE  DECOMPOSITION MICROBIOLOGIQUE Résumé : Emphasis on agricultural production using modern techniques has focused attention on the problem of yield losses due to pests and the need for adequate protection of the crop. Pesticide application is the most practiced method of pest control in rice-based cropping systems. Because of their toxic nature there is a general concern with the potential hazards of pesticides to humans and the environment. The fate of pesticides applied in agricultural ecosystems is governed by the transfer and degradation processes and their interactions . Transfer is a physical process in which the pesticide molecules remain intact. Growing evidence indicates that pesticides are present in food grown on the land in surface and subsurface bodies of water and in atmosphere. Research has established the toxic effects of some pesticides on fish and other aquatic animals, on birds and other wildlife and on human health. Thus this paper reviews the information on the fate of pesticides in rice-based agroecosystems with emphasis on wetland soils.
