Resumo: 	The brazilian coffee growth is very important for the national economy, an activity of relevant economical and social importance. The coffee crop, as any other culture, needs cares in relation to the transport process. Among the factors that interfere and provoke considerable economical losses, the weed competition is one of the most important problems. Crops recently implanted can be submitted to chemical control (driven jet) of weeds. The present work aimed to quantify the intoxication of herbicides in coffee seedlings: glyphosate (180g i.a ha-1); 2,4-D (335g i.a. ha-1); glyphosate + 2,4-D (90g i.a + 167g i.a ha-1); oxyfluorfen (120 and 240g i.a. ha-1). in spite of the fintoxication provoked by herbicides, mainly oxyfluorfen in the largest dose, were characterized as of low intensity, not being enough to take death of plants. Variables as diameter of stem and chlorophyll teor in the leaves in some evaluations not present differences among treatments. Mass dries of stem, number of leaves and plant height were influenced by oxyfluorfen action, mainly in the largest dose. In spite of the reduced phytotoxic action of other herbicides, the damages provoked in the seedlings of coffee can incur in retarded development of plants and consequently reduction in the productivity.
