Efficacy of the soybean symbiotic system under the treatment of soybean (cultivar Almaz) by fungicide Acanto Plus was studied in pot and field experiments. In pot experiment, it was established that the functional activity of symbiosis with full-formed symbiotic apparatus was quite low when the fungicide was applied. Besides, it was noted the decrease of seed weight in this variant. These results indicated the inhibition of soybean-rhizobia symbiosis performance by Acanto Plus. The results of field experiments showed that the using fungicide Acanto Plus promoted more complete implementation of productive capacity of the soybean-rhizobia symbiosis and the increase of seed weight by 21 % as compared to control. It was suggested that such positive changes were caused by effects of studied fungicide on phytopathogens that facilitated restoration of ability to full function of plant symbiotic apparatus.
