This work aimed to evaluate possible symptoms of phytotoxicity, volume of spray droplet deposition on leaves from different positions of plant canopy, consequently, possible control of certain pathogen(s) efficiencies and finally, the interference of the phytotoxicity or control efficiency of the pathogen(s), on the production components of soybean culture. The experimental design used was a randomized blocks, with 7 treatments and 4 repetitions, which are constituted by T1 control, without the use of adjuvant; T2 Fungicide + aliphatic mineral oil; T3 Fungicide + Vegetable Oil Esters; T4 Fungicide + Orange vegetable oil; T5 Fungicide + Paraffinic mineral oil; T6 Fungicide + Fulvic acid; T7 Fungicide + Homeuse vegetable oil. The volume of spray in different positions of plant canopy, phytotoxicity, anthracnose and target spot incidence and soybean yield components were evaluated. After collecting data, the means were submitted to variance analysis by the F test at 5% probability and, afterwards, to comparison of means by Tukey test using Sisvar software. No statistical difference was observed for the evaluated parameters, with no increase in phytotoxins due the use of a certain adjuvant, thus all being efficient in helping in the control of the evaluated diseases. Therefore, the use of a more economical adjuvant such as homeuse soybean oil may be the best alternative for the producer, obtaining satisfactory aid to the fungicide.
