1. RESIDUALS FROM TWO HERBICIDES IMAZETHAPYR AND IMAZAPIC ON PADDY RICE WITH DIFFERENTS SOIL MANAGEMENTS / RESIDUAL DA MISTURA FORMULADA DOS HERBICIDAS IMAZETHAPYR E IMAZAPIC EM ÁREAS DE ARROZ SOB DIFERENTES MANEJOS DE SOLO
Red rice (Oryza spp.) is one of the main limiting factors of rice yield (O. sativa L.) in the world and particularly in the Rio Grande do Sul (RS) state Brazil. The Clearfield technology is a viable and efficient tool for controlling such harmful plant by using imidazolinone herbicides in tolerant cultivars. However, herbicides may persist on the soil after

2. AVALIAÇÃO DO TRANSPORTE DO HERBICIDA PARAQUAT EM SOLOS DO CAMPO EXPERIMENTAL DE BOM JARDIM, RJ / EVALUATION OF TRANSPORT OF HERBICIDE PARAQUAT IN SOILS OF EXPERIMENTAL FIELD OF BOM JARDIM, RJ
This paper presents results of a study, performed in the laboratory, on the mobility of the herbicide Paraquat, investigated from its percolation through soils samples withdrawn from the Experimental Field of Bom Jardim, RJ. It was determined the physical, chemical and mineralogical properties of samples collected in such manner to form a profile of ground l

3. Sorption/desorption and leaching of the herbicide ametryne in soils cultivated with sugar cane and amended with sewage sludge / Sorção/dessorção e lixiviação do herbicida ametrina em solos canavieiros tratados com lodo de esgoto
Several studies have shown the benefits of applying sewage sludge on the physical and chemical properties of the soils. However, just a few of them evaluates the impact of this practice on the behavior of pesticides in tropical soils. The main goal of this research was to evaluate the effects of applying different sources of sewage sludge (Ribeirão Preto, F
