Abstract
<!-- @page { margin: 2cm } --> <p class="western" align="justify">Em situações nas quais a brusone tem pouca importância na sanidade da lavoura de arroz, o controle da mancha parda (<em>Bipolaris</em> <em>Oryzõe</em>) pode mostrar-se altamente eficiente com pulverizações de fungicidas no campo. Assim, realizou-se um experimento em Indiara (GO) com o objetivo de comparar a eficácia de diferentes produtos fungicidas no controle da mancha parda em condições pouco favoráveis à brusone. Foram comparados difenoconazole, propiconazole e tryfloxystrobin em diferentes combinações e dosagens, e os resultados mostraram que, em situações nas quais a brusone tem pouca importância na sanidade da lavoura do arroz, o controle da mancha parda pode mostrar-se altamente eficiente com pulverizações de fungicidas no campo.</p> <p class="western" align="justify">PALAVRAS-CHAVE: <em>Helminthosporium</em> <em>oryzae</em>; controle químico; patógeno; doença.</p>
<!-- @page { margin: 2cm } --> <p class="western" align="justify">In situations where the blight (<em>Pyricularia</em> <em>grisea</em>) is not limiting the rice crop, the brown spot (<em>Bipolaris</em> <em>oryzae</em>) control can be extremely efficient with field sprayings. This experiment was conduced in Indiara (GO) aiming to compare the efficiency of different fungicides in one or two dosages in the control of brown spot under low blight conditions. All treatments showed efficiency in the control of brown spot, with no signifficant difference among them.</p> <p class="western" align="justify">KEY-WORDS: Chemical control; pathogens; disease.</p>
