17. INTERMITTENT AND CONTINUOS FLOODING IN RICE: WATER USE, AGRONOMIC EFFICIENCY AND IMAZETHAPYR, IMAZAPIC AND FIPRONIL DISSIPATION / IRRIGAÇÃO CONTÍNUA E INTERMITENTE EM ARROZ IRRIGADO: USO DE ÁGUA, EFICIÊNCIA AGRONÔMICA E DISSIPAÇÃO DE IMAZETHAPYR, IMAZAPIC E FIPRONIL
Every anthropogenic activity causes environmental impact in some extent. Rice paddy fields area are pointed out as an activity with high potential of pollution due to the large amount of water used to maintain the flooding and the intensive use of pesticides and nutrients that can be transported to the environment. Though, there are other irrigation manageme

18. OXIDATIVE STRESS BIOMARKERS IN CARP (Cyprinus carpio) EXPOSED TO CARBOFURAN AND FIPRONIL INSECTICIDES IN RICE FIELD CONDITIONS / BIOMARCADORES DE ESTRESSE OXIDATIVO EM CARPAS (Cyprinus carpio) EXPOSTAS AOS INSETICIDAS CARBOFURAN E FIPRONIL EM CONDIÇÕES DE LAVOURA DE ARROZ
The contamination of the aquatic environment by pesticides is a problem of global importance because of their toxic effect on non-target organisms. These products may affect toxicological parameters and oxidative stress in fish. The carp is cultivated in southern of Brazil and has great comercial interest. There are few studies in our country regarding the u

22. STUDY OF FIELD PESTICIDE STABILITY OF CARBOFURAN AND QUINCLORAC IN THE WATER OF IRRIGATED RICE CROPS USING SPE AND HPLC-DAD / ESTUDO DA ESTABILIDADE A CAMPO DOS PESTICIDAS CARBOFURANO E QUINCLORAQUE EM ÁGUA DE LAVOURA DE ARROZ IRRIGADO EMPREGANDO SPE E HPLC-DAD
The use of pesticides to control pests, diseases and weeds in crops of agricultural interest aims at the increase of production. The degradation of applied compounds or their conversion into other products, does not necessarily mean the loss of biological activity, and many times, this conversion can result in even more toxic and active products. The study o
