    The plant protection products are products to control pests, diseases and weeds and should be used with technology that allows its deposition in the desired location with minimal loss to the environment. Its use has intensified in recent years due to increased demand for food production, in the same idea the use of mulch as soil conservation practice soil and water. The aim of this study was to quantify the drift in the wind tunnel and the tank simulator agricultural sprays on soil with and without mulch. The experimental design was completely randomized subjected to analysis of variance and the treatment means by the Confidence Interval and the Tukey’s test (P<0.5). The drift was to evaluate in the wind tunnel with two wind speeds and the tank simulator spray two velocities (1 and 2 m s-1). These combined the two types of ground cover (with and without mulch) speeds totaling four treatments with four replications. The spray nozzles were used AXI 11002 at 414 kPa and the all were mixed up with a food color dye Blue FDC for spectrophotometry analysis of deposits. The results showed that the increase of wind speed in the tunnel have more pronounced effects on the drift in soil without mulch compared with soil covered. The increased speed of the spray affect the sediments on artificial collectors. The deposits collected are affected by the presence of straw on the soil surface. The longitudinal or transverse layout of artificial collectors relative to the spray bar produces no differences in the deposits collected.
