The aim of this work is to highlight an effective treatment scheme for combating bacterial blight of soybean (Pseudomonas savastanoi pv. glycinea) and common red spider mite (Tetranychus urticae) under conditions of natural infection and irrigated cultivation. Observations were carried out in 2023, in the experimental field arranged within I.I. Popescu Iulian, in the city of Ianca, Brăila county. The biological material used was the ES Palador variety. Bacterial blight attack was assessed visually, and mites were captured by shaking the leaves onto a white sheet of paper. The frequency of soybean plants attacked by bacterial blight varied between 4.0 and 82.33% in the experimental variants. The common red spider mite attack reduced soybean production by 16.85%. The highest production, of 4895 kg/ha, was obtained in the variants with two treatments against the two biotic factors. Following the research, it can be concluded that among the limiting biotic factors in soybean culture are both the bacterium Pseudomonas savastanoi pv. glycinea and the mite Tetranychus urticae.
