Resumo
A laboratory test was conducted, aiming to verify the effect of dífferent inseticides upon genninating power and vigor of rice seeds, cultivars' IAC - 25 and Rio-Paranaíba, stored at O, 7, 15, 30, 60 and 90 days, after treatrnents.
Gennination tests were settled according routine analysis and evaluated after seven days by counting number of normal and abnormal plantules and dead seeds. For vigor test, the seeds were evaluated in each period at third day, using plantules growing method.
Ali tested products with both cultivars revealed a good gennination rate at storage different periods, excepting fenitrothion that affected significantly germination, detennining an average drop of 22,46% and 32,84%, relative to testimony, for cultivars IAC-25 and Rio-Paranaíba. respectively.
Fenitrothion followed by benfurocarbe were the products whích presented major inhíbition to plantules vigor.
