Soybean is a very important crop to the Brazilian economy, however has showed some
problem, mainly diseases. Fungicides, with physiological effect, have been used with two
finalities: control of diseases and improve the crop production. The aim of this study was to
evaluate the activity of nitrate reductase, dry matter accumulation and yield of soybean
according to application of different strobilurin fungicides. Experimental design used was a
randomized block, with three treatments (T 1 : control; T 2 : Pyraclostrobin; T 3 : Azoxystrobin)
and seven replications. Pyraclostrobin application showed greatest increase of nitrate
reductase activity, dry matter accumulation and productivity, when compared with the control
and Azoxystrobin.
