Resumo: | ABSTRACT: In the search for improved yields, seed treatment by microbiolization has been used as an alternative to chemical treatment. The objective was to verify the physiological and sanitary quality of creole bean seeds, var. Chumbinho, after microbiolization with doses of a commercial product (c.p.) with Trichoderma harzianum (strain ESALQ-1306). The treatments were: T1) 100 mL c.p./100 kg seeds; T2) 150 mL c.p.; T3) 200 mL c.p.; T4) 200 mL of chemical treatment (c.p., 250 g L-1 fipronil + 25 g L-1 pyraclostrobin + 225 g L-1 thiophanate-methyl); and T5) control (without coating of seeds). The tests were: sanitary test (blotter test); germination and first count; accelerated aging, cold germination without soil, speed of germination rate (SGR), seedling shoot and root lengths, and emergence of seedlings in a greenhouse. T. harzianum controlled Aspergillus spp., Penicillium spp. and Fusarium oxysporum. With 100 mL c.p. of T. harzianum dose had better results for the germination and vigor, and this dose it is an alternative to chemical treatment in creole bean seeds.
