Abstract

With the objective of controlling blast disease (Pyricularia oryzae) and brown spot (Helminthosporium oryzae) of rice (Oryza sativa), different fungicides were tested, through seeds treatment, at field culture in low land soil. The results showed, preliminarily and in general terms that fungicides dichlofluanid and terbuconazole propitiated in the stand increase superior to 30% when confronted with standard fungicide mancozeb and testimony with regard to infection level at plants the best results were presented by terbuconazole. Refering to production there was no significative difference between both treatments. Treatments with fungicide terbuconazole individually or in mixture with dichlofluanid showed superiority over testimonies.
