IMPACT DES PESTICIDES VERTEBRES RIZIERES UTILISATION DES PRODUITS CHIMIQUES TOXICITE |
| Résumé : |
In asian countries, production of fish on rice farms is considered by policymakers as a viable option for sustainining food production in lowland areas, augmenting farm income and improving the quality of food available to asian farm households. Rice-fish farming systems hence represent an ideal practice for more efficient utilization of agricultural resources in lowland rice areas. The use of pesticides has been reported to have caused a decline in the practice of rice-fish culture in some parts of the Central Thailand. In the Philippines, some farmers reported detrimental effects of pesticides to fish, but no data is available to substantiate such claims. While potentials include good financial incentives, constraints range from lack of inputs and demand for fish to heavy use of agrochemicals especially pesticides. Among the asian countries reviewed, Korea, Malaysia and the Philippines are reported to heavy users of agricultural pesticides. The two main constraints to increased productivity in irrigated rice-fish farming systems however, are water control and pesticide use, the latter is considered as the more serious constraint because it can be justified in areas where potential rice yields are also high.
Since fish must adapt to management practices for rice, information on toxicity, degradation and residues of pesticides in fish are imperative for the development of a better symbiotic relationship between rice and fish in an integrated farming system.
